Wythnos i fynd...
Dim ond wythnos o gofnodi sydd ar ôl tan ddiwedd Project Bylbiau’r Gwanwyn! Wythnos yn unig tan ddyddiad cau anfon eich cofnodion ata i!
Ble wnaeth y planhigion flodeuo’r wythnos hon?
Yn Lloegr, Ysgol Gynradd RAF Benson oedd y cyntaf i anfon cofnodion am flodau! Yn yr Alban, mae blodau gan Ysgol Gynradd Newburgh ac yng Nghymru, mae blodau i'w gweld yn Ysgol Iau Hen Golwyn, Ysgol Gynradd yr Eglwys yng Nghymru Magwyr, Ysgol Bodafon, Ysgol Gynradd Rogiet ac Ysgol Gynradd Oakfield. Da iawn chi a diolch am anfon eich canlyniadau.
Yw’ch planhigion chi’n blodeuo? O’u cymharu â’r llynedd, mae’n blodau ni’n hwyr iawn yn agor!
Erbyn yr amser hyn y llynedd, roedd crocysau wedi blodeuo mewn 27 ysgol, ond dim ond deg ysgol sydd wedi cofnodi bod eu crocysau wedi agor hyd yn hyn eleni.
Erbyn yr amser hyn y llynedd, roedd 26 ysgol wedi anfon eu cofnodion Cennin Pedr, ond dim ond pedair ysgol sydd wedi gweld cennin Pedr yn blodeuo hyd yn hyn eleni.
Beth yw’r rheswm dros hyn? Dyma nifer ohonoch chi’n sôn am y tywydd oer a’r eira ym mis Chwefror, ac mae eich cofnodion tywydd yn dangos nad näed oes llawer o law wedi disgyn yn ddiweddar. Pan fyddwch chi i gyd wedi anfon eich cofnodion tywydd, bydda i’n edrych am gliwiau i esbonio pam fod y blodau mor hwyr...
Mae Gwyddonwyr Tywydd yn y Swyddfa Dywydd yn dweud bod tymheredd cyfartalog yn y DU dros y gaeaf wedi bod yn ‘fwyn’ eleni – doedd y gaeaf eleni ddim mor oer a gaeafau eraill. Maen nhw hefyd yn dweud bod y DU wedi gweld llai o law nag arfer yn Ionawr a Chwefror. Ys gwn i os yw eich cofnodion tywydd chi yn dangos yr un peth?
Ffeithiau Diddorol:
- Yr enw am astudio’r tywydd yn wyddonol yw Meteoroleg a’r enw am wyddonwyr tywydd yw Meteorolegwyr!
- Pryd mae’r gwanwyn yn dechrau? Pan fydd Meteorolegwyr yn cofnodi’r tywydd byddan nhw’n dweud bod y gwanwyn yn dechrau ar 1 Mawrth ac yn gorffen ar 31 Mai. Ond mae llawer o bobl yn dweud bod y gwanwyn yn dechrau ar gyhydnos y gwanwyn ar 20 Mawrth – yr wythnos hon!
Hoffech chi wneud Ymchwiliad Gwyddonol Gwych gyda’ch planhigion? Rydw i wedi meddwl am arbrofion arbenig y gallwch chi roi cynnig arnyn nhw yn yr ysgol! Allwch chi dwyllo eich crocws? All eich cennin Pedr symud? Cliciwch y ddolen i weld mwy: Syniadau ymchwil Athro’r Ardd.
Eich cwestiynau, fy atebion:
Ysgol Nant Y Coed: Some pupils have 6 crocuses in one bulb. Prof P: Gosh that is unusual!
St Mary's Catholic Primary School: Our flowers are being very shy and staying out of sight! Prof P: That’s very sweet! Hopefully they will feel a bit braver soon and show their faces!
Greyfriars RC Primary School: We are having fun are you? Prof P: I am so glad! Yes I am having fun with my bulbs too, thanks for asking!
Newport Primary School: Weather just got colder this week. Crocus bulbs are through but there are none flowering just now. Prof P: Good work Newport Primary, flowering is very late indeed this year.
St Joseph's Primary School (Penarth): We are disappointed that our bulbs have not flowered yet but we can see that some of them are growing well and are nearly ready to flower. Hopefully we will have some interesting pictures to send you next week. Prof P: I hope so too St Joseph’s! I would love to see your pictures.
Gladestry C.I.W. School: went to Cardiff on a school trip on thurs Prof P: I hope you had fun in Cardiff.
Glyncollen Primary School: Our daffodils and crocuses have opened. We will send you photos this week. Prof P: Hooray! I look forward to seeing your photos.
Coppull Parish Primary School: Sorry for not doing the weather on Monday. Prof P: That’s okay Coppull Parish, thanks for letting me know and keep up the good work.
Bwlchgwyn C P School: we have 30 shoots. Prof P: That’s great news!
Thorneyholme RC Primary School: Hi p.p on Friday we got 220mm of rain. Prof P: That really is a lot of rain!
Ysgol Porth Y Felin: To p.p we didn't have a record on thursday because of a school trip, and we’ve started measuring the tallest plant which is now 21.5cm tall. Prof P: Did you have fun on your school trip? Good measuring Ysgol Porth Y Felin.
Diolch yn fawr
Athro’r Ardd
Bron ar Ben!
Helo blantos y bylbiau,
Cofiwch bod angen i chi anfon pob adroddiad tywydd a chofnod blodau ata i erbyn ddydd Gwener 29 Mawrth. Dim ond tair wythnos sydd ar ôl i chi anfon eich data!
Peidiwch poeni os nad yw’r planhigion wedi blodeuo eto, mae tair wythnos yn amser hir. Mae canlyniadau’r blynyddoedd diwethaf yn awgrymu bydd y rhan fwyaf o’r blodau wedi agor erbyn diwedd Mawrth.
Bydd pob disgybl yn yr ysgolion fydd yn anfon eu cofnodion yn derbyn Tystysgrif Gwyddonydd Gwych fel yr un yn y llun! Ond bydd pawb yn derbyn gwobr arbennig arall eleni – pensel Gwyddonydd Gwych i gofnodi canlyniadau eich arbrofion, felly cofiwch anfon eich cofnodion!
Ble wnaeth y planhigion flodeuo’r wythnos hon?
Dangosodd blog yr wythnos diwethaf taw Ysgol Nant Y Coed oedd y cyntaf yng Nghymru i gofnodi bod eu blodau wedi agor, a’r wythnos hon mae mwy o blant yr ysgol wedi anfon cofnodion blodeuo! Mae blodau Ysgol Nant Y Coed yn tyfu’n dda iawn. Ys gwn i os welodd Llandudno lawer mwy o haul na gweddill Cymru?
Mae Greyfriars RC Primary School yn St Andrews, yr Alban wedi cofnodi hefyd bod y crocysau yn blodeuo ac mae Ysgol Iau Aberdaugleddau yn Sir Benfro wedi cofnodi bod crocysau a chennin Pedr wedi blodeuo! Da iawn i’r ddwyn ysgol.
Pan fydd y cennin Pedr yn blodeuo, cofiwch fynd ati i dynnu llun! Gallwch chi anfon eich lluniau ata i a chymryd rhan yn yGystadleuaeth Darlunio Cennin Pedr. Bydda i’n chwilio am ddarluniau prydferth, ond mae’n rhaid labelu darnau’r blodyn yn glir hefyd. Gallwch chi weld esiamplau gwych o enillwyr y blynyddoedd diwethaf yma.
Eich cwestiynau, fy atebion:
Rhydypenau Primary School: We had rain over the weekend, that is why our gauge was full. Prof P: Thank you for the explanation Rhydypenau, that's really helpful!
Ysgol Nant Y Coed: Some of the crocus bulbs have flowered so we're sending that information now too. Prof P: Fantastic news! Thanks for your flowering records.
SS Philip and James Primary School: We really enjoyed doing it and remembered to do it every day, we hope that we can do it again soon. Phil+Jim bulb team aka Isaac and William. Prof P: I am so pleased that you are enjoying it so much – I love recording the weather too!
Henllys CIW Primary: still no flowers. Prof P: It's exciting to see your flowers open, but your report that they have not opened is very valuable scientific information too! It could tell us a lot about how cold it has been this winter or how much sunshine we have had.
St Joseph's Primary School (Penarth): We have noticed that our plants continue to grow but we are keeping a very close eye on them to see which one will flower first - we can't wait! Prof P: I feel the same every morning when I look at my plants too.
Greyfriars RC Primary School: 11 daffodils are in bud. A's crocus is the only one growing but all the other daffodils but A's, why is A's daffodil not growing? Prof P: This is a very good question! I’m sorry that your daffodil is not growing A, you haven’t done anything wrong! I am glad your crocus is growing instead. Sadly we do have a small number of bulbs every year that do not grow, it happened to some of mine last year. The reason it happens is unclear. When a daffodil doesn't make a flower gardeners say that the plant has gone 'blind' - as it has no flower head.
Ysgol Porth Y Felin: we had our holidays on the 11 - 15 week so we'll skip a week. everythings ok there hasn't been much rain and the temperature has been a little high!
from porth y felin. Prof P: Many thanks!
Kilmaron Special School: The school was on holiday on Thursday and Friday. On Wednesday we had very heavy snow and although the rain gauge only had 3mm in it there was almost 6cm of snow by 2pm. The gauge is in quite a sheltered place as we had problems with a pupil seeking it out and emptying it. Prof P: Good idea to move your rain gauge to keep it safe.
Glyncollen Primary School: We hope our flowers open this week as well. Prof P: Fingers crossed!
Kilmaron Special School: Still no signs of our crocus bulbs although the ones planted years ago in our other raised beds are blooming and the ones in the grass next to our raised bed are almost out. Prof P: Keep watching them Kilmaron!
Diolch yn fawr

Cofnodion blodau 1af yr Alban a Chymru!
Llongyfarchiadau i Tulliallan Primary School am anfon cofnodion blodau Bylbiau’r Gwanwyn cyntaf y flwyddyn! Dim ond un diwrnod oedd rhwng dyddiadau blodeuo’r crocysau a’r cennin Pedr, gyda’r crocysau yn blodeuo ar 17 Ionawr a’r cennin Pedr cyntaf yn blodeuo ar 18 Ionawr.
Gan fod yr Alban ymhellach i’r Gogledd na Chymru a Lloegr byddan nhw fel arfer yn cael gaeafau oerach a mwy o eira. Mae hyn yn golygu y bydd planhigion fel arfer yn blodeuo’n hwyrach. Llynedd agorodd y blodau yn gynt yng Nghymru a Lloegr, felly mae’n dipyn o syndod bod y blodau cyntaf eleni wedi ymddangos yn yr Alban! Dyma un o’r pethau gwych am fod yn wyddonydd – gall canlyniadau arbrofion yn aml ein synnu ni!
Yr ail ysgol i anfon eu cofnodion blodau ata i oedd Ysgol Nant Y Coed yn Llandudno. Agorodd crocysau tri o’r plant ar yr un diwrnod, 1 Mawrth. Dyma’r cofnodion cyntaf yng Nghymru, a hynny ar Ddydd G?yl Dewi! Da iawn Ysgol Nant Y Coed!
Ys gwn i ble fydd y blodau nesaf yn agor?
Pan fydd eich blodau chi’n agor, cofiwch anfon eich data ata i. Gallwch chi weld ar y map ble mae’r blodau wedi agor yn barod.
CYNGOR CRAFF
- Gall pob disgybl yn y dosbarth anfon eu cofnodion blodau. Mae’r holl ddata fyddwn ni’n ei dderbyn yn cael ei ddefnyddio i ganfod dyddiad blodeuo cyfartalog pob ysgol. Gwyliwch y siart crocysau a’r siart cennin Pedr i weld y tablau yn newid wrth i fwy o ddata gyrraedd. Mae’n bwysig ofnadwy bod pob disgybl yn anfon eu cofnodion, fel bod y wefan yn gallu cyfrifo dyddiad blodeuo cyfartalog yr ysgol.
- Bydd y cennin Pedr yn troi ei ben i lawr ychydig cyn blodeuo. Fydd y blodyn ddim wedyn yn llenwi â d?r ar ôl agor.
Byddwn i wrth fy modd yn gweld lluniau o’ch blodau chi hefyd. Gofynnwch i’ch athro e-bostio unrhyw ffotograffau ata i!
Dyw fy mhlanhigion i yma yng Nghaerdydd heb flodeuo eto. Mae’r blagur ar un o’r crocysau yn dechrau troi’n borffor, felly efallai eu bod nhw ar y ffordd. Mae blagur ar y cennin Pedr hefyd ond mae nhw dal yn wyrdd.
Eich cwestiynau, fy atebion:
St Nicholas Primary School rain gauge stolen. Prof P: Sorry to hear that St Nicholas Primary. I have put a new one into the post for you, I hope it arrives soon.
Ysgol Y Ffridd Glawiad Dydd Llun yn llawn ers y gwyliau. Athro'r Ardd: Mae'n rhaid ei bod hi wedi bwrw hen wragedd a ffyn yn yr ysgol dros y gwyliau! Diolch am roi gwybod i fi.
Milford Haven Junior School Temp in playground was much colder because of the wind chill factor. Prof P: Brrrr! I hope you were all wrapped up warm when you went outside to play.
Ysgol Porth Y Felin to pp we have a problem with one of the plants. It has creamy browny little things in the pot that look like mini shell pastas. We don't know what they are. ysgol porth y felin. Prof P: Gosh, they sound curious. I wonder if they could be the brownish leaves that protect the plant just before the shoots start to grow? Maybe you could take a photo and ask your teacher to send it to me? I might know what they are if I saw them!
Ysgol Nant Y Coed We have buds on the crocus and daffodils now but none of them have opened yet. The mystery bulb has grown the biggest! Prof P: That’s great news! Keep an eye on them and let me know as soon as they open.
Darran Park Primary Mystery plant has grown quite well the rest of the bulbs are slowly growing. Prof P: Thanks for your plant update Darran Park Primary.
Glyncollen Primary School Many thanks for our new rain gauge. You also sent us a new thermometer but on a slip of paper in the box it said St. Mary's. We were wondering if it was meant for us or should we send it back to you? Can you please let us know. The leaves on our flowers are growing well. Bye for now - Yr.4 Prof P: Oops! I sent out two rain gauges on the same day and things must have got mixed up. Sorry Glyncollen. I have emailed your teacher about the thermometer – thanks for letting me know about the mix up.
Greyfriars RC Primary School Dear Professor Plant, we are a bit confused because only one crocus is flowering and only one daffodil is flowering. Prof P: Congratulations Greyfriars School! You are now the second Scottish School to have flowers! You now need to enter you flower data on to the website to make it OFFICIAL! Remember: You can enter flower data as soon the very first flower opens. You record the date it opened and the height of the tallest part of your plant. Then as each new flower opens you can enter its data on the website too – you don’t have to wait until they are all open. Plants grow at different rates – some grow quickly, some take longer to grow - just like children! I am sure your other flowers will 'catch up' soon.
Diolch yn fawr

Wythnos Hinsawdd 4-10 Mawrth 2013
Helo blantos y bylbiau!
Mae hi’n Wythnos Genedlaethol Hinsawdd wythnos nesaf – amser da i feddwl am newid hinsawdd, sut mae’n effeithio arnon ni a sut allwn ni ofalu am y blaned.
Ers 150 mlynedd mae gwyddonwyr ym mhob rhan o’r byd wedi bod yn mesur tymheredd a glawiad, yn union fel y byddwch chi’n ei wneud wrth ymchwilio i fylbiau’r gwanwyn! Mae’r gwyddonwyr wedi gweld bod tymereddau ar draws y byd yn codi, a bod patrwm glawiad yn newid hefyd.
Gallai tywydd cynhesach a rhagor o law helpu’r crocysau a’r cennin Pedr i dyfu, ond mae cynhesu byd-eang hefyd yn golygu bydd mwy o dywydd eithafol – eira trwm, stormydd, llifogydd a sychder!
Rydyn ni wedi gweld llawer o lifogydd a mwy o eira yn y DU dros y blynyddoedd diwethaf. Llynedd, cyhoeddodd y Swyddfa Dywydd taw 2012 oedd yr ail flwyddyn fwyaf gwlyb yn y DU ers dechrau cofnodi, a’r flwyddyn wlypaf erioed yn Lloegr.
Mae nifer o’r gwyddonwyr gorau yn cytuno bod lefelau llygredd yn cyfrannu at gynhesu byd-eang, felly beth allwn ni ei wneud i helpu?
Defnyddio ynni’n effeithiol! Os ydyn ni’n defnyddio llai o ynni, rydyn ni’n creu llai o lygredd. Sut? Gallwn ni wneud pethau bach syml bob dydd i arbed llawer o ynni gartref neu yn yr ysgol. Er enghraifft, mae diffodd y teledu neu’r cyfrifiadur pan fydd neb yn ei ddefnyddio yn arbed llawer o ynni!
Beth arall allwch chi ei wneud i arbed ynni? Beth am drafod yn y dosbarth? Gallech chi hefyd edrych ar y cyflwyniad yma ar gynhesu byd eang – mae rhai syniadau eraill yma am arbed ynni.
Os oes diddordeb gyda chi mewn dysgu beth arall allwch chi ei wneud ar gyfer Wythnos Hinsawdd, ewch i’r wefan.
Eich cwestiynau, fy atebion:
Thorneyholme RC Primary School PP, We were off on Wednesday afternoon, and our mystery blubs are growing. Prof P: Can you guess what they are yet Thorneyholme or are they still a mystery?
Lakeside Primary Sorry about all the non recorded dates. Prof P: That’s okay! Sometimes I have to miss a day recording too. Keep up the good work.
Ysgol Capelulo We have not got any flowers yet :( Prof P: Don’t be sad Ysgol Capelulo, my plants haven’t got flowers yet either… I am sure they will come soon.
RAF Benson Primary School Some our daffodils and crocuses have started growing. Prof P: That’s great news!
Newport Primary School It has been quite good weather here this week with no rain and some sunshine but the last couple of days have been really cold and quite dull. On Sunday 17th we had an almost spring day and we were all able to get out and have a good time as it was really sunny and felt quite warm. Prof P: Excellent weather reporting NewportPrimary School! Really detailed, thank you! It has been very cold here in Cardiff too.
Balcurvie Primary School Our big rainfall on Monday was after the half term holiday when it snowed heavily! Great fun for us but not for our poor wee bulbs! Prof P: Sounds like you have been having some extreme weather in Scotland! I am glad you have been enjoying it Balcurvie.
Diolch yn fawr

Hanner Tymor Hapus
Gobeithio i chi fwynhau y gwyliau hanner tymor!
Wnaethoch chi gael hwyl y tu allan dros hanner tymor? Pan fydda i yn mynd am dro bydda i’n cadw llygad bob tro am flodau yn tyfu fel sydd gyda fi yn yr ardd... ydych chi wedi gweld blodau cyfarwydd? Gallwch chi fod yn Wyddonydd Gwych unrhyw bryd, wrth chwarae yn yr ardd neu wrth gerdded i’r parc neu i’r ysgol. Dyma rai cwestiynau i’ch helpu chi. Mwynhewch ymchwilio!
Allwch chi weld unrhyw flodau arall yn tyfu? Allwch chi weld cennin Pedr neu grocysau yn tyfu? Ydyn nhw’n dalach neu’n fyrrach na’ch planhigion chi? Ydyn nhw wedi dechrau blodeuo eto?
Anfonodd Kilmaron Special School neges i ddweud eu bod nhw wedi sylwi ar rywbeth diddorol ar iard yr ysgol...
Kilmaron Special School Mae’r cennin Pedr mewn potiau wedi dechrau blaguro ac mae’r plant hefyd yn gweld rhai cennin Pedr yn ymwthio o’r ddaear am y tro cyntaf. Does dim golwg o’r bylbiau crocws eto. Rydyn ni wedi plannu cennin Pedr ar hyd y llwybr at yr ysgol ac yn yr iard chwarae synhwyraidd ac maen nhw’n dalach na phlanhigion Ymddiriedolaeth Edina. Roedden ni’n meddwl efallai eu bod nhw’n fath gwahanol, ond fyddwn ni ddim yn gwybod tan eu bod nhw’n blodeuo.
Ymchwilio gwych gan Kilmaron Special School! Mae cennin Pedr yn y ddaear yn aml yn ymddangos yn gynt na chennin Pedr mewn potiau ac rydw i wedi bod yn pendroni am hyn hefyd! Rydych chi’n gywir hefyd i ddweud bod rhai mathau o gennin Pedr yn tyfu’n gynt. Rheswm posibl arall yw bod y planhigion yn y ddaear yn cael eu gwarchod yn well rhag tywydd oer na’r planhigion mewn potiau. Os yw ein bylbiau yn oeri efallai byddan nhw’n tyfu ychydig yn arafach! Mae hefyd yn bosibl bod y cennin Pedr yn yr iard chwarae wedi cael eu plannu rai blynyddoedd yn ôl. Mae bylbiau bach fel ein rhai ni yn tyfu’n arafach yn eu blwyddyn gyntaf, ond byddan nhw’n blodeuo eto bob gwanwyn ac efallai y byddan nhw’n tyfu’n gynt flwyddyn nesaf.
Eich cwestiynau, fy atebion:
Coppull Parish Primary School I'm worried that we've done something wrong with our bulbs. You see crocuses and daffodils are sending up shoots in our neighbourhood; but none of ours are peeping through at all. Prof P: Don't worry Coppull Parish School! As I've explained above bulbs in pots often grow slower. I hope you will have some growth very soon, keep sending me updates and let me know how your bulbs get on.
St Joseph's Primary School (Penarth) We are very excited because we have started to notice that some of our bulbs have started to sprout - we can't wait for them to flower. It is half term for us next week so we will be interested to see how our bulbs have grown when we return to school on 18th February! Prof P: I hope you all had a nice break, your bulbs might have grown a lot when you get back!
Darran Park Primary We have growth in all of our pots. Some pots contain more than 1 shoot. They seem to be growing quickly now. The mystery pot is showing lots of growth. We are on half term next week so won't be able to send in any records. Prof P: The mystery bulbs are very exciting aren’t they?
Henllys CIW Primary Some crocus shoots are coming up. Prof P: Thanks for your report Henllys CIW Primary, it won’t be too long now until they flower.
Ysgol Porth Y Felin To pp the plants are again all ok they’ve grown a lot since last Friday you can see the temperature has been quite high and there hasn’t been much water. From Ysgol Porth Y Felin. Prof P: I’m glad your plants are okay, excellent weather reporting too.
Milford Haven Junior School They started to sprout and it’s getting warmer. Prof P: Great news Milford Haven! My bulbs are sprouting too, I can see their leaves but I can’t see any flowers yet.
Rogiet Primary SchoolDear Professor Plant and Baby Bulb, Some of our bulbs have started to appear we hope to see some more after half term. We are looking forward to finding out what our mystery bulb might be. From Year 4. Prof P: HelloRogiet Primary School, I can’t wait to see what my mystery bulbs will look like too.
Ysgol Nant Y Coed The spring bulbs haven't flowered yet but they’re growing. The mystery bulbs are growing the highest. Prof P: I love a good mystery! Do You?
Ysgol Bodafon The weather is getting warmer. Prof P: You are quite right Ysgol Bodafon, hopefully this will help our plants to flower soon.

Am dywydd mawr!
Rydych chi wedi bod yn anfon adroddiadau tywydd cymysg iawn i fi dros yr wythnosau diwethaf! Cwympodd llawer o eira mewn rhai ysgolion, ond dim mewn ysgolion eraill. Da iawn chi i gyd am anfon eich adroddiadau drwy gydol y tywydd rhewllyd.
Eira mân eira mawr …
Dyma nifer o ysgolion yn cofnodi eira…St. Mary's Catholic Primary School, Ysgol Bwlchgwyn, Ysgol Gynradd Glyncollen, Stanford in the Vale Primary School, Thorneyholme RC Primary School, Coppull Parish Primary School, Freuchie Primary School, Balcurvie Primary School, Ysgol yr Eglwys yng Nghymru Gladestry ac RAF Benson Primary School.
Dyma rhai ysgolion yn dweud wrtha i eu bod nhw ar gau oherwydd yr eira... Manor Primary School, St Joseph's Primary School, Ysgol Gynradd yr Eglwys yng Nghymru Henllys, Ysgol Nant Y Coed, Ysgol Gynradd Rhydypennau ac Ysgol Gynradd Rogiet!
Dyma rhai ysgolion yn gweld ychydig bach o eira, neu ddim eira o gwbl... Diolch i Stepping Stones Short Stay School ac Ysgol Iau Aberdaugleddau am eich adroddiadau.
Ers yr eira, mae nifer o ysgolion wedi cofnodi gwyntoedd uchel, stormydd a llawer o law, ond wrth edrych drwy’r ffenest galla i weld yr haul yn tywynnu – dyna dywydd amrywiol mewn ychydig wythnosau! Mae’r egin cennin Pedr a crocws talaf yn yr ardd yn 7cm o daldra erbyn hyn. Pa mor dal yw eich egin chi?
Cyngor Craff mewn tywydd rhewllyd: Os oes eira neu rew yn eich mesurydd glaw, dewch ag e i’r ystafell ddosbarth i doddi cyn cofnodi. Cofiwch arllwys y d?r allan ar ôl iddo doddi a’i roi yn ôl y tu allan!
Eich cwestiynau, fy atebion:
St Joseph's Primary School (Penarth) Our school was closed last Friday because of snow so we couldn't get in to check on our freezing bulbs. We have noticed, however, that one of our bulbs has started growing whilst the others are snug underneath the compost in their pots. We tried to think about why this might have happened and wondered whether it is because that particular bulb was planted by you, Prof. Plant and maybe you have encouraged it to grow!? We are pleased to see that the weather has got a bit warmer and are hoping that this means that our bulbs will start to grow. We are very keen to see them flowering! Prof P: Thanks St Joseph’s! Well, I am very green fingered! It’s very exciting waiting for your flowers to arrive isn’t it?
Rogiet Primary School The bulb pots were full of snow this week, we were worried they would die but Mrs Carter said they would be all right! Prof P: Don’t worry, Mrs Carter is right, they are very hardy little plants so I’m sure they will be okay.
Ysgol Nant Y Coed We are sorry for sending the records late because school was closed because of the snow last Friday. Prof P: No problem! Thank you for sending them in when you could.
Stanford in the Vale Primary School Wow... what a bitter cold week, and all the snow we have had! All our bulbs are completely covered in snow... and more snow is expected tonight! Monday's snow/rainfall was frozen, so we brought the recordings inside and allowed to melt! (We hope this was the correct thing to do!) :-) Prof P: Well done Stanford in the Vale that was exactly the right thing to do!
Gladestry C.I.W. School We have started measuring the few bulbs that have come out. The daffodils and mystery bulbs have come out; we think the mystery bulbs are snowdrops, as they have grown very fast. Prof P: That’s a very good guess!Keep watching them and let me know if your guess is right.
Balcurvie Primary School One of the extra bulbs that we planted in a pot and left it in the classroom has began to sprout! We were all very excited. We have also had a very wet week! Prof P: That is exciting Balcurvie! I hope you enjoy watching it grow. I wonder when your outdoor bulbs will catch up?
SS Philip and James Primary School We thought it went well except we forgot to pour out the water once so we counted the amount of water added on the next day. We enjoy doing it, Phil and Jim Team. Prof P: That’s okay, thanks for letting me know and keep up the good work. I’m glad you’re enjoying it.
Ysgol Y Ffridd Dim Record Dydd Iau oherwydd ysgol wedi cau (Dim Dwr yn yr ysgol). Prof P: Athro’r Ardd: Diolch am y wybodaeth gan Ysgol Y Ffridd. Gobeithio bod y d?r wedi trwsio erbyn hyn.
Darran Park Primary 42 of the bulbs have sprouted. Prof P: Gosh that’s a lot! Well done Darran Park Primary.
Ysgol Porth Y Felin To pp, plants are all ok the temperature rised alot on Tuesday! there was a storm on Saturday night so there was loads of rain on Monday. Happy planting!!! Prof P: Great reporting Ysgol Porth Y Felin, hopefully all that rain will help your plants to grow.
Rhydypenau Primary School A very interesting week of weather! Prof P: I agree!
Diolch yn fawr

Mae’r crocws yn dechrau blodeuo ddiwedd mis Ionawr, felly bydd eich planhigion chi’n blodeuo unrhyw ddiwrnod! Am gyffrous! Cofiwch edrych ar eich planhigion crocws bob dydd i weld os yw’r blodau wedi agor a chofnodi’r dyddiad a thaldra’r planhigyn.
Bydd blodyn y crocws yn borffor gydag anther a stigma oren (y rhannau yng nghanol y petalau). Gallan nhw dyfu i daldra o 10cm.
Peidiwch â phoeni os nad yw’r blodau wedi ymddangos eto! Bydd y tywydd oer a’r eira dros yr wythnosau diwethaf wedi arafu’r broses. Wrth i’r tymheredd gynhesu gall y blodau ymddangos yn sydyn, felly cadwch lygad arnyn nhw!
Diolch yn fawr

Egin ac eira!
Hiâ Cyfeillion Bylbiau!
Rwy'n amau y bydd llawer o'n potiau o dan eira ar gyfer y dyddiau nesaf! Bydd hyn yn golygu y bydd llawer o ysgolion ar gau. Os ydych yn cael eira rhowch nodyn yn yr adran sylwadau pan fyddwch yn anfon eich cofnodion tywydd.
Dilynwch y ddolen hon i weld yr holl gofnodion tywydd sydd wedi cael eu hanfon i'r graddau. Dewiswch ysgol, yna 'tywydd'.
Dyma rai lluniau o fy egin. Byddwch yn gweld bod y rhai wnes i blannu yn hydref 2011 wedi tyfu llawer mwy na'r rhai wnes i blannu hydref 2012.
Os oes gennych egin yn barod, cymerwch olwg ar fy lluniau i helpu gweithio allan beth yw beth.
Dyma fideo sy'n dangos sut y bydd eich egin yn tyfu.
Eich cwestiynau:
St Mary's Catholic Primary School: We have no records for Monday because it was an inset day. Some of our daffodil bulbs have come through the soil. We have taken photographs and will send them by e-mail. Prof.P: I look forward to seeing them St.Mary’s.
Ladybank Primary School: Thank you for our new thermometer! Prof.P: No worries, thanks for letting me know it arrived safely.
Glyncollen Primary School: Our bulbs have started to grow over the holidays. We hope the frost doesn't get to them. Yr.4. Prof.P: Don’t worry year 4, they are quite tough.
SS Philip and James Primary School:
Happy New Year! A few daffodil shoots are peeping out of the ground and in one or two pots. Quite a few shoots are emerging in the 'Mystery Bulbs' pot and they are a red/green colour compared to the daffodils shoots which are green. Prof.P: How exciting, not seen my mystery bulb shoots yet.
Greyfriars RC Primary School:
Some are sprouting already! All is good. I am really enjoying this project! Prof.P: glad to hear the bulbs are starting to grow and that you are enjoying.
St Joseph's Primary School (Penarth)
Happy New Year Prof.Plant. We have started to notice a few green shoots in some of our pots and are very excited about the plants beginning to grow. We have talked about the weather forecast for next week and think that we may be sending you photos of snow covered pots! (St. Joseph's Primary School, Penarth.) Prof.P: Yes you were right. Some snow in Cardiff but not enough!
Rhydypenau Primary School:
when we got back to school after the Christmas holidays, our rainfall gauge was full, so we must have had a lot of rain in a fortnight. Prof.P: Yes, we had lots of rain over the holidays – a bit too much! Many people had flooding which must have been awful at Christmas.
Henllys CIW Primary:
Some shoots but no flowers. Prof.P: The flowers will come soon.
Auchtertool Primary School:
When we came back from our Christmas break some of our bulbs were showing growth - not only the ones in pots but also some of those we had planted in the ground! Prof.P: Excellent news!
Ysgol Porth Y Felin:
hello p.p the plants are growing quite quickly but we didn't write down Monday because of teacher training. Prof.P: Thanks for letting me know.
Ysgol Nant Y Coed:
This week the bulbs have started to grow, mostly the mystery bulb. The weather was warm at the beginning and at the end it was cold. Prof.P: Great update, Nant Y Coed.
Tynewater Primary School:
We had 50mm of rainfall on Tuesday because we had been on holiday for two weeks and nobody had emptied the rain gauge. Prof.P: Yes, mine was the same. Thanks for noting the reason.
Dechrau newydd!
Blwyddyn Newydd Dda - Gwyddonwyr Gwych! Gobeithio chi wedi cael siawns i ymlacio a nawr yn barod i ymchwilio!
Ar yr adeg hon o'r flwyddyn pethau'n dechrau mynd yn gyffrous iawn. Nawr yw'r amser i wylio eich potiau i weld os oes unrhyw beth yn dechrau tyfu. Mae fy egin cennin Pedr eisoes wedi ymddangos! Danfon llun i mi os mae eginech chi wedi dechrau ymddangos.
Gallai gymryd mis arall neu hyd yn oed chwe wythnos tan fy mlodau yn ymddangos. Mae'r cyfan yn dibynnu ar ein tywydd - os yw'n troi'n wirioneddol oer, yna bydd y twf yn arafu. Os bydd yn aros yn gynnes byddant yn tyfu yn gyflymach.
Y cam nesaf... Defnyddiwch y cyflwyniad PowerPoint i ddarganfod sut i gadw cofnodion blodau. Cofiwch fod yn rhaid i bob un ohonoch roi gwybod i mi pan fydd eich blodau ar agor er mwyn derbyn eich Tystysgrif Gwyddonwyr Gwych.
2012 oedd yr ail flwyddyn wlypaf ar gofnod yn y DU a'r gwlypaf erioed yn Lloegr, y Swyddfa Dywydd gyhoeddi.
Mae'r glaw a oedd yn achosi mwy na 8,000 o gartrefi a busnesau i ddioddef llifogydd arwain at gyfanswm o 1,330.7 mm o law ar gyfer y flwyddyn, dim ond 6.6mm byr o'r flwyddyn y DU gwlypaf a gofnodwyd yn 2000 (1337.3mm).
Dadansoddiad gan y Swyddfa Dywydd yn awgrymu y gall y DU yn mynd yn fwy gwlypach fel newid yn yr hinsawdd yn achosi aer cynhesach i gario mwy o dd?r. Dyddiau o law eithafol - glaw disgwyliedig unwaith bob 100 diwrnod - wedi digwydd bob 70 diwrnod yn 2012. Am ragor o wybodaeth am hyn gweler adroddiad hwn gan y Guardian.
Diolch yn fawr

Ddeuddeg cwsg
Ni allaf gredu ei fod ond ddeuddeg cwsg tan Nadolig! Rwyf wedi anfon cerdyn Nadolig atoch chi gyd yn y post. Ddiolch i chi gyd am y gwaith caled rydych wedi ei wneud hyd yn hyn.
Dyma'r chweched wythnos a'r olaf o gofnodi tan Ionawr felli Nadolig Llawen oddi wrth Bwlb bychan a fi.
Rwyf wedi mwynhau'r holl sylwadau a chwestiynau dwi wedi cael yn ystod y flwyddyn hon ac yn edrych ymlaen at ateb mwy yn y Flwyddyn Newydd.
Wyf yn gobeithio bod chi gyd yn cael gwyliau gwych ac yn dychwelyd ym mis Ionawr yn awyddus i weld sut mae eich bylbiau yn ei wneud. Os ydych yn pryderu efallai na fydd eich bylbiau yn ddiogel dros y Nadolig, mynd â nhw adref gyda chi - ond cofiwch fod yn rhaid iddynt gael eu cadw y tu allan!
Mae'r tywydd wedi bod yn oer iawn mewn mannau yn ystod yr wythnos neu ddwy ddiwethaf, ond rhagwelir y bydd yn cael cynhesach. Adroddodd Ysgol Harwell -10 ° c ddydd Iau diwethaf. Oer iawn yn wir! A allwch chi gadarnhau hyn yn gywir?
Fy hoff garol Nadolig yw'r 'Holly and the Ivy' oherwydd ei fod yn cynnwys dau o'n planhigion bytholwyrdd brodorol. Roedd y Celtiaid yn defnyddio planhigion hyn i ddathlu Byrddydd y Gaeaf ac wrth gwrs y maent yn cael eu defnyddio gan Gristnogion i ddathlu'r Nadolig.
Os nad ydych yn gwybod ei fod yma yn y geiriau: http://www.carols.org.uk/the_holly_and_the_ivy.htm
Eich cwestiynau, fy atebion:
Greyfriars RC Primary School: We are really enjoying this! Prof.P: So glad to hear it!
DarranPark Primary: There aren't any signs of growth yet. Prof.P: Give it time; you should see something in January.
GlyncollenPrimary School: We have seen a pattern in our temperatures this week. We have also found out a way to stop our rain gauge from falling over. We hope we don't have any snow next week. From Glyncollen year 4 Prof.P: Great to hear you are seeing patterns in your weather data and that you have found a way to stop your rain gauge from falling over. Please let me know how you do it?
BalcurviePrimary School: We have had a lot of ice this week and freezing temperatures. We also had snow over last weekend and on Thursday. Prof.P: I hope it gets warmer for you at the weekend!
St Joseph's Primary School (Penarth): We have noticed how much colder is has got this week. There has been some ice on our plant pots and we feel really sorry for the poor bulbs! Prof.P: Don’t worry too much I’m sure they will be fine.
KilmaronSpecialSchool: Records for rainfall on days with negative temperatures may not be correct as the water had frozen and expanded so reading may be higher than actual water collected Prof.P: Thanks for letting me know Kilmaron; I will make a note of it. If it happens again melt it before you measure. Thanks
Ysgol Pencae: It rained cats and dogs on Friday and was milder. Did it rain more in Cardiff? Prof.P: We only had 10mms of rain in Cardiff a quarter of what you recorded!
