Helo Gyfeillion y Gwanwyn,
Wel, rydych chi wedi bod yn brysur! Rwyf wedi derbyn 75 o gofnodion blodeuo dros yr wythnos ddiwethaf, sy'n creu cyfanswm o 175 planhigyn wedi blodeuo!
I'r rhai ohonoch sy’n dal i aros am eich blodau dyma rai awgrymiadau:
- Bydd eich planhigyn wedi blodeuo pan fyddwch yn gallu gweld yr holl betalau, heb y casyn allanol sy'n eu diogelu tra eu bod yn datblygu (gweler y llun ar y dde).
- Cofiwch fesur mewn mm!
- Mesurwch o bwynt uchaf y pot i bwynt uchaf y blodyn.
- Cofiwch gofnodi'r dyddiad wrth rannu gwybodaeth flodeuo ar wefan Amgueddfa Cymru!
- Gadewch sylwadau wrth wneud cofnodion, dyma eich cyfle i ddweud wrthyf beth ydych chi wedi’i fwynhau neu beidio am y project!
- Rhannwch eich lluniau! Rwyf wedi rhannu lluniau ysgolion ar Twitter. Os nad yw eich ysgol yn defnyddio Twitter gall eich athro neu athrawes e-bostio lluniau i mi.
Does dim llawer i fynd nawr! Dim ond dwy wythnos o gasglu a chofnodi data tywydd sydd ar ôl!
Cofiwch, y 27ain o Fawrth yw'r diwrnod olaf i gofnodi eich data tywydd. Mae'n rhaid i chi wneud hyn er mwyn ennill eich tystysgrifau Gwyddonydd Gwych a chael cyfle i ennill taith natur yn yr amgueddfa!

The Blessed Sacrament Catholic Primary School: We were very excited this week as there were lots of buds on our crocuses. The weather has been getting warmer and today the first crocus flowers opened in the sunshine and we had to measure them carefully, H and J. Prof P: Well done H and J! I hope you have enjoyed studying the development of your plants. There are other experiments you can do that demonstrate how your flowers respond to light and heat. I will send these to your teacher but you can also find them on the website under ‘Professor Plant’s investigation ideas’. Keep up the good work!
Rivington Foundation Primary School: On Monday we had snow! And on Thursday we were on a school trip. Prof P: Well Rivington Foundation Primary School, you’ve had quite an exciting week! And you still managed to document your weather records, thank you very much!
Stanford in the Vale Primary School: Still no sign of bulbs in pots flowering yet, we think the ones in the ground are doing better, as the roots have more space to grow, unlike the pots which have restricted space! It’s lovely and sunny here today, with a good sunny forecast for the weekend. When we return to school on Monday we should hopefully start to see our bulbs flowering. Prof P: Hi Stanford in the Vale Primary, I’m pleased to hear that you are observing other plants and discussing the effects of environment on growth and development. I hope the sun over the weekend spurs on your plants, it shouldn’t be long now so watch them closely!
Our Lady of Peace Primary School: The bulb's still have not came out yet but one of them is almost out. Prof P: It shouldn’t be long now Our Lady of the Peace Primary! Watch the flower buds carefully to see how they open. The spathe will begin to split lengthways as the bud grows! If your teacher has a camera you might be able to take pictures that show the different stages of the bud flowering!
Thorn Primary School: We are very sorry but we were unable to submit plants data this week as there was building work taking place at school and we could not safely get to the thermometer and rain collector. We will be fine to collect our data this week. Prof P: Thank you for letting me know Thorn Primary School, and not to worry! I look forward to seeing your data next week.
Our Lady of Peace Primary School: My name is T and my flower was first to open. It was outside when it opened but when we brought it inside it opened even more. We were amazed. Even our teacher was amazed. Prof P: Hi T. I’m glad that you have been studying your plants so closely, they are fascinating things! Did you discuss why the flower reacted to being moved inside? I suspect your classroom was a lot warmer than the playground!!
Swiss Valley School: Hello how do we record the mystery bulbs please? Prof P: Hi Swiss Valley School. You can record the mystery bulbs flowering dates for your own records in the class room, but there is no need to record them on the NMW website. Schools that are taking part in the Edina Trust extension projects were given an extra 20 daffodil bulbs to plant in the ground, and those schools are asked to document the flowering dates for these on the Edina Trust website. This is so that they can compare the flowering dates of those in the ground to those in pots and think of reasons why these might be different. Have you noticed differences in the development of your mystery bulbs to your bulbs in pots? Can you think of reasons for this?
Ysgol Iau Hen Golwyn: We enjoyed measuring them. Prof P: I’m glad to hear that you are enjoying the project Ysgol Iau Hen Golwyn! Keep up the good work.
Stanford in the Vale Primary School: All our crocus have flowered and they are looking so pretty. What a lovely week of warmer weather, and finally the rain came today, we are so in need of more rain.....we looked at the weather data as a group and noticed Oxfordshire have had little rain this year! Prof P: Hi Stanford in the Vale Primary. What a lovely post, and it’s nice to see a positive spin on rain! I’m glad that you are using the resources on the map to study readings from other schools! You can also use the Met Office WOW website to look at readings in other areas.

Helo Gyfeillion y Gwanwyn,
Rwy'n gobeithio cawsoch Ddydd GÅµyl Dewi gwych ddoe!
Mae Dydd GÅµyl Dewi yn Åµyl genedlaethol yng Nghymru sy'n dathlu Dewi Sant, nawddsant Cymru. Mae hwn yn gyfnod pryd mae'r hanes a thraddodiadau Cymru yn cael eu dathlu. Mae bwydydd traddodiadol fel cawl / lobscaws a gacennau cri yn cael eu paratoi, a gwisg draddodiadol ac arwyddluniau Cymreig yn cael eu gwisgo. Mae arwyddluniau Cymreig haddurno ar ddiwrnod GÅµyl Dewi yn cynnwys y genhinen (sy'n symbol o Dewi Sant) a'r Cennin Pedr. Mae'n ddiddorol bod y gair Cymraeg am ddwy yn mor debyg!
Roeddwn i'n meddwl y byddai'n ddiddorol i'r ysgolion yn Lloegr a'r Alban i weld pa mor bwysig yw'r Cennin Pedr yng Nghymru. Oeddech chi'n dathlu Dydd GÅµyl Dewi? Os nad, a oes ddyddiau eraill yr ydych yn ei dathlu? Gallech roi gwybod i mi am y rhain yn yr adran 'sylwadau' pan fyddwch yn cofnodi data tywydd yr wythnos hon!
Edrychwch ar y lluniau isod!

Helo Gyfeillion y Gwanwyn,
Mae gen i newyddion cyffrous! Mae'r dyddiadau blodeuo cyntaf wedi eu cofnodi ar y wefan!
Llongyfarchiadau i Ysgol Deganwy – blodeuodd eu Crocws cyntaf nhw ar y 21ain o Chwefror, yn 90mm o uchder. Blodeuodd Crocws cyntaf Ysgol Tal Y Bont a Ysgol Bancyfelin ar y 23ain o Chwefror yn 65mm o uchder. A blodeuodd Crocws cyntaf Ysgol Gynradd Ynysddu ar y 25ain o Chwefror yn 50mm o uchder. Maent yn disgwyl i ddau arall flodeuo unrhyw ddiwrnod nawr!
Blodeuodd planhigion Swiss Valley CP School yn gynharach fyth, dros y gwyliau hanner tymor.
Mae Silverdale St John's CE School wedi adrodd bod rhai o'r crocws gafodd eu plannu mewn teiars wedi blodeuo. Mae un yn 110mm o daldra!
A heddiw, cefais dystiolaeth ffotograffig drwy Twitter i dangos bod Ysgol Gynradd Llanharan o leiaf dau blanhigyn Crocws sef wedi tyfu'n llawn! Gwelodd y dosbarth un ohonyn nhw ar agor heddiw!
Cofiwch gofnodi'r diwrnod blodeuo ac uchder eich planhigyn ar wefan Amgueddfa Cymru. Ond, peidiwch â gwneud hyn tan mae'r petalau yn gwbl weladwy a chofiwch fesur taldra mewn milimedrau!
Byddwn wrth fy modd yn cael lluniau o'ch blodau i’w rhoi ar wefan yr Amgueddfa a fy nhudalen Twitter. Gofynnwch i'ch athrawon i anfon y rhain ataf os yn bosib!
Hoffwn hefyd weld pa mor artistig ydych chi! Felly, mae gennyf weithgaredd i chi ei gwneud unwaith y bydd eich blodau wedi agor! Hoffwn i chi i dynnu darlun manwl o'ch planhigyn a labelu ei wahanol rannau. Mae hon yn ffordd wych o ddod i adnabod eich blodau yn well ac i weld pa mor gymhleth y gall pethau bach o'r fath fod. Mae hefyd yn ddiddorol iawn i gymharu Cennin Pedr a'r Crocws – allwch chi weld y tebygrwydd a'r gwahaniaethau? Mewn sawl ffordd mae pob blodyn yn debyg iawn, er eu bod yn edrych yn hollol wahanol ar yr olwg gyntaf!
Dyma gêm hwyliog yn ymwneud â labelu planhigion o wefan Bitesize y BBC.
Edrychaf ymlaen at weld eich lluniau.

Stanford in the Vale Primary School: We had snow on Tuesday! Bitter cold all week. Prof P: Wow Stanford in the Vale Primary, you have had cold weather! -2 on Tuesday – burrr!
Rivington Foundation Primary School: Our daffodils in pots started sprouting last week, now between 1 and 4 cms. Daffodils in pots no sign yet. Probably too cold in the ground. Professor Plant: Hi Rivington Foundation Primary, I’m glad to hear your bulbs are sprouting! It is exciting to see how fast they grow once they start to show above the soil. Usually, the plants in the ground would grow first because they are slightly warmer than your plants in pots. But this depends on a number of things, such as how much frost you have had! I’m sure they will show themselves soon, maybe they are waiting for it to get a little warmer!
Chryston Primary School: Sorry but we were off for 3 days and sadly a bulb got squished because it is near the playground and a ball landed of top of it. The good news is the bulbs are starting to grow. Next week we will start recording the height of the bulbs. Prof P: Oh I am sorry to hear that you lost one of your bulbs! I hope you are all sharing so that no one is too upset – these things do happen! I’m glad to hear that your bulbs have started growing though! It’s interesting to document how quickly they grow, and to see that each one grows at its own pace!
Saint Anthony's Primary School: We are enjoying taking the measurements and are delighted at how well our bulbs are progressing. Prof P: Hi Saint Anthony’s Primary, I’m glad to hear you are enjoying the project. I very much enjoy studying all the weather records that are sent in. And I especially like receiving lovely comments that show me others enjoy this project as much as I do! Keep up the good work Bulb Buddies.
Glyncollen Primary School: We have had good fun so far doing spring bulbs investigation! Prof P: I’m glad you are enjoying the project Bulb Buddies! There are lots more experiments and investigations you can do if you are enjoying this one, why not have a look at the MET Office website for idea!
Saint Anthony's Primary School: We have noticed that the temperatures have recently been rising and falling. Prof P: Hi Saint Anthony’s Primary, I’m glad to hear that you are studying and comparing your weather records. You have had a bit of a jump, from -2 on Wednesday to 11 on Thursday! Differences like this can result from taking readings at different times of day, as the temperature will be consistently lower in the morning than in the afternoon! This is why it’s important to always try to take the readings at around the same time. However, this can also result from changes in the weather. I’m guessing it was a lot sunnier and less cloudy on Thursday compared to the rest of the week!
Our Lady of Peace Primary School: We hope our bulbs flower soon. We enjoyed planting them. Prof P: I’m sure it won’t be long now Our Lady of Peace Primary! One of my Crocus plants is nearly big enough, but it will be a while yet before my other plants flower! Isn’t it interesting to see that all of our plants are developing differently even though we planted them on the same day!
Keir Hardie Memorial Primary School: We have started to see that our bulbs are starting to grow. Some of our bulbs during the extremely windy weather blew over and were nearly out of the plant box and plant pot. However, we have seen some growth in a number of our plant pots and are hoping they will grow further. For the other ones that had blew over, we replanted them just in case there is any hope. This was a few weeks ago so hopefully we will see some change. Prof P: Hi Keir Hardie Memorial Primary, you did the right thing by re-planting your bulbs. I have my fingers crossed that they will still grow for you! I’m glad to hear that some of your plants have started to grow and that you are monitoring them so closely. Keep up the good work!
Glyncollen Primary School: We have had a broken thermometer on Monday and Tuesday. Professor Plant: Hi Glyncollen Primary. I’m sorry that your thermometer wasn’t working. But I’m glad to see that you fixed it or got a new one, and that you still took your rain fall readings. Good work!
The Blessed Sacrament Catholic Primary School: Nearly all our bulbs have shoots now the weather is a bit warmer and the mystery bulbs have buds so it looks like we may have some flowers soon. E and O. Prof P: Ooo this is exciting! Once your mystery bulbs have flowered let me know what type of plant you think they might be! Keep up the god work!
Stanford in the Vale Primary School: Another strange week with the weather....high winds, cold and heavy rain, then beautiful sunshine! Our plants in the ground look as if they could be showing signs of opening.....but the one in pots seem rather behind....so we are on constant watch! Kind Regards, Gardening Club. Prof P: Hi Stanford in the Vale Primary Gardening Club! I’m glad to hear that your plants are doing well, and that you are comparing the growth of the plants in the ground to the plants in pots. It’s very interesting that these are developing differently, can you think of reasons why this might be?
Glyncollen Primary School: Some of our spring bulbs are starting to grow and our crocus! Prof P: That’s good news Glyncollen Primary, keep a close eye on them now because they’ll grow quickly!

Helo Gyfeillion y Gwanwyn,
Hoffwn ddymuno hanner tymor gwych i chi! Peidiwch â phoeni am eich planhigion yn ystod y gwyliau, bydd nhw'n iawn! Ond plîs gwiliwch arnynt beth gyntaf wrth gychwyn nol yn ysgol. Gall y planhigion crocws blodeuo mo gynnar a mis Ionawr, felly dylem ni disgwyl nhw yn fuan iawn!
Rwyf wedi cael jôc wych arall gan L o Thorn Primary School:
Q. Why do you call beetroot beetroot?
A. Because you have to beat the root to get them out!!
Mae mwy o ysgolion wedi anfon diweddariadau cyffrous ar eu planhigion:
Silverdale St. John's CE School: The daffodils are about 5cm tall and one of them is around about 8cm tall! Prof P: Fantastic news Silverdale St. John's CE School you must be looking after them very well!
The Blessed Sacrament Catholic Primary School: This week is cold again with very frosty mornings, but we can now see some crocus shoots as well as the daffodils. The mystery bulbs have the tallest shoots. K M. Prof P: I’m excited that your Crocus plants have shown through. Isn’t it interesting how different the shoots look! Keep up the good work Bulb Buddies!
Ysgol Nant Y Coed: It was a very dry week last week. Also, our daffodils are about 12-14cm tall now. Prof P: Wow Ysgol Nant Y Coed, make sure you keep a close eye on your plants! It doesn’t sound like it will be long now before you see your first flowers.
Ysgol Iau Hen Golwyn: I like this job. Prof P: I’m glad to hear it! There are lots of other experiments you can try if you are enjoying this one. Try the MET Office website for some great ideas for half term: http://www.metoffice.gov.uk/education/kids/things-to-do/experiments
Rivington Foundation Primary School: We think that the temperature on Tuesday,Thursday and Friday was because the sun was hitting straight on to the thermometer. Prof P: Wow Rivington Foundation Primary! What high readings for week 6! That shows summer weather in February! Well done for spotting that this is unusual and questioning why your readings are so high. I think you are right and it must be because your thermometer was in the sun and you took the readings at the warmest time of day! I suggest that you turn the thermometer slightly so it is not in direct sunlight. This will give you more accurate readings. You are well on your way to becoming Super Scientists!!
Carstairs Primary School: Unfortunately we are unable to take the temperature because our temperature monitor has went missing with all of the snow. Prof P: Wow, that must be a lot of snow you are having Carstairs Primary School! Thank you for taking the rain fall readings despite the wintery weather! I see these were high all week, did you have to take the rain gauge inside to melt the snow before taking your readings?
Hi Kirkton Primary School. Just to let you know that you’ve had the coldest weather reported so far for week 6 at -6ÌŠ!! Brrrrr!! And Thorn Primary School had the second warmest reading of week 6 at 13ÌŠ. I wonder how this will affect your plants! I’ll be watching both of your weather records and flowering dates with interest to compare!
Mwynhewch eich gwyliau Gyfeillion y Gwanwyn!!

Helo Gyfeillion y Gwanwyn,
Rwy am rannu ambell lun gyda chi. Cofiwch, os gofynnwch i’ch athro neu athrawes yrru lluniau o’ch planhigion i mi, gallaf eu rhannu gydag ysgolion eraill sy’n rhan o’r project! Mae gen i ddiddordeb mawr mewn lluniau sy’n dangos y newid mewn tymhorau – fel blodau’r gwanwyn yng nghanol eira’r gaeaf!
Cennin Pedr yn Sain Ffagan. Allwch chi weld pa blanhigion sydd â blagur, a pha rai sydd wedi blodeuo?
Mae rhywfaint o ddryswch wedi bod ynghylch pryd i gofnodi dyddiad blodeuo ar-lein. Gallwch fonitro taldra eich planhigion bob wythnos a gadael i mi wybod yn yr adran ‘sylwadau’ wrth i chi gofnodi’r tywydd. Ond dim ond wedi i’r planhigyn flodeuo y dylech gofnodi ‘dyddiad blodeuo’ a thaldra’r planhigyn ar ddiwrnod blodeuo.
Edrychwch ar y llun uchod o Gennin Pedr yn Sain Ffagan. Cafodd y llun ei dynnu ar ddiwrnod oer, felly nid oedd y blodau wedi agor yn llawn. Ond, gallwch weld pa rai sydd wedi blodeuo trwy edrych yn ofalus. Os yw’r holl betalau i’w gweld yn glir yna mae’r planhigyn wedi blodeuo. Cyn blodeuo mae’r petalau yn cael eu gwarchod gan gasyn tynn fel hwn:
Blagur yw hyn. Pan fydd y blodyn wedi aeddfedu, a’r tywydd yn ddigon cynnes, bydd y casyn yn dechrau agor. Gall hyn gymryd ychydig oriau neu rai dyddiau! Efallai y gallwch weld hyn yn digwydd, os wnewch chi wylio’r planhigion yn ofalus iawn! Pan fyddwch yn gallu gweld yr holl betalau a’r casyn wedi disgyn gallwch fesur taldra’r blodau a chofnodi hyn ar y wefan. Wedi i chi wneud hynny bydd blodyn yn ymddangos ar fap yn dangos lle mae eich ysgol.
Gallwch fesur uchder eich planhigion i weld pa mor sydyn mae nhw’n tyfu. Os yw’r planhigion yn dal yn fach gallwch eu mesur o dop y pridd. Ond, pan fyddwch yn mesur er mwyn cofnodi ar y wefan, dylech fesur o dop y pot blodau i bwynt uchaf y blodyn.
Ydych chi wedi cymharu uchder y blodau yn eich dosbarth? Oes yna wahaniaeth mawr yn uchder y planhigion a pha mor aeddfed ydyn nhw, neu ydyn nhw i gyd yn debyg? Beth am y planhigion sydd wedi’u plannu yn y ddaear? Yw’r rhain yn fwy na’r rhai mewn potiau? Pam hynny tybed? Gallwch ddweud beth ydych chi’n feddwl yn yr adran ‘sylwadau’ wrth i chi gofnodi’r tywydd yr wythnos hon!
Gyrrwch eich straeon a lluniau i’r blog blodau a dilynwch Athro’r Ardd ar Twitter!
Daliwch ati Gyfeillion y Gwanwyn!
O.N. Peidiwch â phoeni os nad yw eich planhigion wedi dangos eto. Mae’n dal yn gynnar ac rwy’n sicur bydd yn gwneud cyn bo hir! Rhwy'n dal yn aros am rai o'n planhigion i dangos uwchben y pridd...
