Eich sylwadau:

Ysgol Y Wern: Roedd Dydd Llun yn stormus a wyntog iawn.

YGG Tonyrefail: Roedd e yn wythnos gwlyb iawn.

Beulah School: Roedd llawer o law ar dydd Llun!

Rougemont Junior School: Heavy rain and sleet on Friday, hope our bulbs will enjoy a cold shower.

Rougemont Junior School: Our baby bulbs are safe and sound in their pots and we have them on display.

Trellech Primary School: We had lots of rain at the weekend so the rain fall on Monday was high. We can’t wait for our flowers to start growing.

St Paul's C.I.W. Primary: Hello pr.plant. We are proud of our work. Professor Plant: And so you should be St Paul’s, keep it up Bulb Buddies!

Ysgol Rhys Prichard: Really cold on Monday. A lot of Rain on Monday too. No Rain on Wednesday, Thursday and Friday.

Ysgol Glanyfferi: Variety of temperatures throughout the week.(R, K and A).

Alston Lane Catholic Primary School: Thursday 17th November - the rainfall was 25mm but I could not upload this as only 20 and 30 were options on the databank. Professor Plant: Hi Alston Lane, when entering the reading please round the figure to the nearest 10mm. So you were right to enter 30mm! But a reading of 24mm would be entered as 20mm on the website. Ellel St John's CE Primary School had a similar problem: ‘Lots of heavy rain on Monday 14th November, we actually measured 31mm of rain but it wasn't available on the drop down menu.’ Keep up the good work Bulb Buddies!

Ysgol Y Wern: Roedd hi'n oer iawn ar Ddydd Gwnener i gymharu ar ddechrau'r wythnos

Lawhead School: The plants were atrociously frozen. They were so frozen that when I tipped the pot out, nothing fell out of it. - J K and T L. Professor Plant: Wow, that is frozen! Don’t worry about your bulbs though, the soil will be insulating them against the cold!

Carnbroe Primary School: The weather has been very frosty and icy all week. On Thursday our class went out to check on the plants. The soil in our pots was frozen but have decided that our bulbs will still flower. Professor Plant: Well done for checking on your plants! I’m sure that your plants will still flower too. Lawhead Primary reported the same: Lawhead School: The week got colder towards the end. The soil in our pots is frozen solid!

Auchenlodment Primary School: After a wet and mild weekend it's been a very cold week. The plant pots have been covered with frost. Professor Plant: A few schools have noticed frost in their pots! I’m sure your bulbs are nice and warm buried in the soil. Keep up the good work Bulb Buddies.

Rougemont Junior School: Not sprouting yet but a few popping out. Professor Plant: Oh dear Rougemont, I hope they are sprouting! If it’s not a green shoot that you can see, but the brown top of the bulb, then you’ll need to put a few more handfuls of soil on top of them!

Stanford in the Vale Primary School: Hello, we have noticed that some of the bulbs have started to pop up. Professor Plant: Hi Stanford in the Vale, do you mean that shoots have begun to appear? If so that’s great news!

Arkholme CE Primary School: It has been very wet as you can see in the data. It has been very cold, we have had our first frost of the winter. On three days of the week when we were collecting the weather data it was raining! Thank you. Professor Plant: Hi Arkholme CE Primary. Thank you for collecting the weather data even though it was raining. Be careful if the school yard is frosty! Keep up the good work Bulb Buddies!

Llanharan Primary School: 7th - 11th November and 14th - 18th November results have been mixed up - is there any way they could be swapped please? Sorry! Professor Plant: Hi Llanharan Primary,  thank you for letting me know the data was mixed up. Not to worry, I have swaped these dates for you. Keep up the good work Bulb Buddies|!

Auchenlodment Primary School: It was dry on Monday but there was a lot of rain over the weekend which was the 5mm recorded on Monday. We have felt the temperature drop over the week, it's getting very cold! Professor Plant: Well done for observing the weather over the weekend even though you are not taking readings on these days. Keep up the good work Bulb Buddies!

St Robert's R.C Primary School: We had a busy week this week and we went on a trip to Cardiff Museum on Friday! Professor Plant: Hi St Robert’s Primary. Wow, I hope you enjoyed your trip!

Broad Haven Primary School: What a week we have had gales-rain-sleet-hail-sun-rainbows. The sea has been very rough with huge waves. Professor Plant: Wow Broad Haven Primary, you really have had a mixed week in terms of weather. It’s interesting to see the effect a strong wind can have on the sea!

Stanford in the Vale Primary School: The weather has turned really cold today.
Been training people to do this experiment during the week. From R xxx Professor Plant: Hi R, thank you for training others to take weather readings, even in the cold! Keep up the good work Bulb Buddy!

St Clare's Catholic Primary School: A very chilly and wet week. We even have some snow today! Professor Plant: I hope you enjoy the snow St Clare’s Catholic Primary! Make sure you wrap up warm!

Ysgol Rhostyllen: We're really enjoying it! Professor Plant: Hi Ysgol Rhostyllen, I’m glad to hear you’re enjoying the project. Keep up the good work Bulb Buddies!

Carnbroe Primary School: It was so cold on Wednesday that we decided to check our plants to make sure they were alright, they looked ok. It rained really heavily all day Thursday and the ground was very wet and muddy. Professor Plant: Hi Carnbroe Primary, well done for checking on your bulbs! The soil will be keeping the bulbs insulated against the cold. Keep up the good work Bulb Buddies.   

Ysgol Rhys Prichard: A lot of rain on Wednesday compared to Thursday and Friday.
It was colder on Wednesday compered to Tuesday. Professor Plant: Hi Ysgol Rhys Pritchard, well done for comparing the results throughout the week. You might find it interesting to use the maps on the Spring Bulbs website to compare your results to those from other schools!

Coppull Parish Primary School: Again the children made all the recordings with no supervision. Well done. Professor Plant: Fantastic work Coppull Primary!

Chorley St James Primary School: It was a very wet week in Chorley! The temperature stayed below 13 degrees. Professor Plant: Hi Chorley Primary, fantastic work! Why not use the graphs on the Spring Bulbs website to compare your results to those of other schools? Keep up the good work Bulb Buddies!

 

Helo Cyfeillion y Gwanwyn,

Diolch am rannu eich sylwadau gyda'r data tywydd wythnos dwytha. Rwyf wedi atodi rhai yn isod. Mae llawer ohonoch yn ddweud bod y tywydd wedi oeri a bod 'na mwy o law. Mae rhai ohonoch chi hyd yn oed wedi cael eira! Dyma pam dwi am esbonio sut mae meteorolegwyr (gwyddonwyr tywydd) yn mesur eira. 

Mae mesur faint o law sy’n disgyn yn hawdd o’i gymharu â mesur faint o eira sy’n disgyn. Fydd eira ddim yn bihafio! Bydd yn aml yn cael ei chwythu gan y gwynt ac yn lluwchio, sy’n golygu bod yr eira’n ddwfn mewn mannau ond yn llawer llai dafliad carreg i ffwrdd. Oherwydd bod yr eira’n disgyn yn anghyson, bydd y mesuriadau o’r llefydd yma’n anghywir! Dyna pam mae’n rhaid mesur mewn mannau gwastad, agored ymhell o ble fydd eira’n lluwchio. Bydd eira hefyd yn chwarae gemau gyda’r Meteorolegwyr sy’n ceisio ei fesur – bydd yn toddi’n ddŵr, cyn rhewi fel iâ. Felly dyw’r eira sy’n cael ei fesur ddim bob tro yn cyfateb i faint o eira sydd wedi disgyn. Mae eira newydd yn disgyn ar ben hen eira hefyd, ac mae’n anodd dweud faint o eira sydd wedi disgyn o un diwrnod i’r llall. 

Mae’n rhaid i’r meteorolegwyr gofio holl driciau’r eira a meddwl am ffyrdd i ddarganfod faint o eira sydd wedi disgyn. Byddan nhw’n edrych ar gwymp eira (faint o eira sy’n disgyn mewn diwrnod) a dyfnder eira (cyfanswm dyfnder yr eira, hen a newydd). Un ffordd o fesur cwymp eira yw gyda ffon bren. Bydd y meteorolegwr yn gosod y pren mewn lleoliad agored lle na fydd eira’n lluwchio ac yn mesur yr eira bob chwech awr. Drwy glirio’r eira o’r pren ar ôl ei fesur, dim ond eira’r diwrnod hwnnw fydd yn cael ei fesur, a gall y gwyddonydd ddweud faint o eira sydd wedi cwympo ar y diwrnod hwnnw. 

Gallwn ni hefyd fesur eira wedi toddi ar ffurf dŵr. Gallwch chi felly ddefnyddio’ch mesurydd glaw i fesur cwymp eira. Os taw dim ond ychydig o eira sy’n cwympo, bydd yn toddi yn y mesurydd beth bynnag, ond os yw hi’n bwrw’n drwm, ewch â’r mesurydd i mewn ac aros iddo doddi’n ddŵr. Gallwch chi wedyn fesur y dŵr fel rydych chi wedi’i wneud bob wythnos, a’i gofnodi fel glawiad yn eich cofnodion tywydd. 

Os oes eira ar lawr a bod digon o amser i arbrofi, beth am fynd ati i fesur dyfnder yr eira? Y cyfan sydd ei angen arnoch chi yw pren mesur (neu pren eira os ydych chi am siarad fel gwyddonydd gwych!). Gwthiwch y pren i’r eira tan ei fod yn cyffwrdd y ddaear a chofnodi pa mor ddwfn yw’r ddaear fesul milimedr. Rhaid i chi fesur o arwyneb gwastad (fel mainc) mewn lle agored lle nad yw’r eira’n lluwchio. Rhaid i chi gofnodi o leiaf tri mesuriad i gyfrifo dyfnder cyfartalog yr eira lleol. Cyfrifwch y cyfartaledd drwy adio’r cofnodion gwahanol a’u rhannu gyda’r nifer o gofnodion. Os ydw i’n cofnodi tri dyfnder o 7cm, 9cm a 6cm, rhaid i fi adio pob rhif (7 + 9 + 6 = 22) cyn rhannu gyda 3 (22 / 3 = 7.33). Dyfnder cyfartalog yr eira felly yw 7.33cm. 

Mae gorsafoedd tywydd fel y Swyddfa Dywydd (MET Office) wedi troi at dechnoleg i ddyfeisio dulliau newydd o fesur dyfnder eira. Edrychwch ar y llun o un o orsafoedd eira’r Swyddfa Dywydd. Mae nhw’n defnyddio synwyryddion laser i fesur dyfnder yr eira ar yr arwyneb gwastad. Gall meteorolegwyr gasglu data o bob cwr o’r wlad wrth wasgu botwm – llawer haws a mwy dibynadwy nag anfon pobl allan i’r oerfel gyda phren eira! Mae pob un o orsafoedd eira’r Swyddfa Dywydd i’w gweld ar y map – oes un yn agos atoch chi? 

Os yw hi wedi bwrw eira, cofiwch fesur y cwymp gyda’r mesurydd glaw neu’r dyfnder gyda phren eira a nodi’r canlyniadau fel ‘Sylwadau’ wrth uwchlwytho eich cofnodion wythnosol. Bydd yn ddiddorol cymharu dyfnder yr eira â chwymp yr eira yn y mesurydd glaw! 

Daliwch ati Gyfeillion y Gwanwyn,

Bydd eich gwobrau yn y post erbyn wythnos nesa Cyfeillion y Gwanwyn.

Rwyf isio ddweud diolch mawr i bob ysgol a rhannodd ei lluniau. Oedd o’n hyfryd gweld y gwaith rydych wedi gwneud, fallu plîs cadwch ymlaen yn rhannu gyda ni!

Cafodd llawer o sylwadau diddorol ei rhannu gyda’r cofnodion tywydd wythnos dwytha. Dyma rhai ohonyn nhw:

 

Eich sylwadau

YGG Tonyrefail: Mae wedi bod yn wythnos sych iawn....a very dry week Professor Plant!

Ysgol Tal y Bont: Mae'n oeri yn araf yn nhal y bont wythnos yma yr athro planhigin

St. Charles Primary School: The weather this week was cold and mostly dry.

The Blake CE Primary School: It has been a bit damp this week especially at the end of the week. It is starting to feel a lot colder as winter is coming.

St Robert's R.C Primary School: It's been getting colder!!

Boston West Academy: We think the weather has been warmer than we would have expected for this time of year and there has been hardly any rain.

Darran Park Primary: We have noticed that the temperature has started to drop over the week. It has been mostly dry, however, there was a shower on Thursday night.

Ysgol Iau Hen Golwyn: It was fun. There wasn't much rain.

Broad Haven Primary School: A dry sunny week cold in the mornings but warm by the afternoon. Rain expected this weekend -but only showers

Stanford in the Vale Primary School: Monday we had no school. Enjoying looking at our planted bulbs! We have had some frosty mornings.

Carnbroe Primary School: We have had a sunny, dry but cold week. We have decided to make predictions about our bulbs and we are all excited to find out what will happen.

Henllys CIW Primary: We have had no rain and we have been allowed out to play!!!

Hudson Road Primary School: It has been really nice Autumn weather. We hope our bulbs are warm in the soil.

Ysgol Rhys Prichard: First frost of the Autumn this Wednesday!

Auchenlodment Primary School: We all enjoyed collecting the data and from next week we will work in pairs to collect the data.

 

Trellech Primary School: Thank you for letting us complete the bulb activity we really enjoyed taking our measurements. Diolch yn fawr.

Professor Plant: Thank you for taking part Bulb Buddies, I’m glad that you are enjoying the project!

 

Breckon Hill Primary School: We have measured the temperature and the rainfall in the location of the pots (front of the school) and in the flower beds (at the back of the school). We have noticed that it is slightly warmer at the front of the school as this area gets a little bit more sun.

Professor Plant: It’s fantastic that you are observing these differences and logging them Bulb Buddies! Which bulbs do you think will flower first?

 

Our Lady of Peace Primary School: This was our first week. Mr Kelly showed us what to do.

 

Barmston Village Primary School: We are noticing some liquid in the rain gauge when it has not rained. We think it is like the dew that has been on the grass as there is only a little bit of it.

Professor Plant: Hi Bulb Buddies, well done for noticing the liquid and questioning how it will have come to be in the rain gauge! I suspect that you are right and that the water is the result of dew forming inside the gauge. Air contains water vapour, and the higher the temperature the more water vapour it contains. When the temperature drops (as it often does overnight) the air cools and releases the water vapour it has been carrying. When surfaces or objects cool to the point that the air around them can no longer contain its level of water vapour, the air will condense and form droplets on the surface of the object. Fantastic Work Bulb Buddies!

 

Law Primary School: All pupils in Primary 5 have really enjoyed planting the daffodils and crocus. They are working in pairs to record rainfall and temperature each day.

Helo Cyfeillion y Gwanwyn,

Rwy’n gobeithio bod pawb wedi mwynhau eu gwyliau hanner tymor!

Rwyf isio ddweud diolch mawr i bawb am eich gwaith caled ar y diwrnod plannu. Cafodd 13,829 o fylbiau ei blannu ar draws y wlad! Welais o’r llunia bod pawb wedi cael llawer o hwyl yn helpu!

Mae Cofnodion Tywydd yn cychwyn o 1 Tachwedd. Plîs wnewch yn siŵr bod eich mesurydd glaw ai’ch thermomedr wedi ei chadw mewn lle addas wrth ymyl eich bylbiau, fel medrwch gymryd eich mesurau cyntaf pnawn fory!

Mae’n syniad da i ymarfer cymryd cofnodion tywydd. Fedrwch chi wneud hyn wrth ychwanegu dŵr at y mesurydd glaw a chymryd mewn tro i gofnodi’r mesur. Wedyn, fedrwch gymharu i weld os mae pawb wedi cymryd yr un mesur.

Mae 'na adnoddau dysgu ar y wefan i helpu paratoi am gymryd cofnodion tywydd. Rwyf wedi atodi hyn rhag ofn bod rhai heb ei gweld eto. Mae’r adnodd hyn yn helpu ymateb cwestiynau pwysig fel ‘pam mae mesur tywydd yn bwysig i’n harbrawf o’r effaith mae’r hinsawdd yn cael ar ddyddiad blodeuo bylbiau gwanwyn’!

Defnyddiwch eich siart tywydd i gofnodi'r glaw a’r tymheredd pob ddiwrnod ysgol. Ar ddiwedd yr wythnos, cofnodwch mewn i’r wefan i rannu eich canfyddiadau. Fedrwch hefyd gadael sylwadau a chwestiynau i fi ymateb yn fy blog nesaf!

Dylai ysgolion sef yn cymryd rhan yn brosiectau ychwanegol yr Edina Trust rhannu ei chanlyniadau wythnosol ar wefan Moodle yr Edina Trust hefyd.

Plîs gadewch i mi wybod sut ydych yn wneud. A rhannwch luniau trwy Twitter ac e-bost.

Cadwch ymlaen a'r gwaith called Gyfeillion y Gwanwyn,

Athro’r Ardd

Helo Cyfeillion y Gwanwyn,

Mae'n bron diwrnod plannu! Ydych chi'n barod? Dyma rai adnoddau defnyddiol i'ch paratoi ar gyfer plannu eich bylbiau a gofalu amdanynt dros y misoedd nesaf! Mae'r rhain hefyd ar wefan Bylbiau'r Gwanwyn i Ysgolion: https://amgueddfa.cymru/bylbiau-gwanwyn/

Dylech ddarllen y dogfennau hyn:

• Llythyr oddi wrth Athro'r Ardd (cyflwyniad i'r prosiect)

• Mabwysiadu eich Bwlb (trosolwg o’r gofal fydd angen ar eich Bylbiau)

• Plannu eich bylbiau (canllawiau ar gyfer sicrhau arbrawf teg)

A chwblhewch y gweithgareddau hyn:

• Tystysgrif Mabwysiadu Bylbiau

• Creu Labelai Bylbiau

Mae'n bwysig eich bod yn darllen y rhain oherwydd maent yn cynnwys gwybodaeth bwysig! Er enghraifft, ydych chi'n gwybod pa mor ddwfn mae angen i chi blannu eich bylbiau? Neu sut i labelu fel mae’n glir lle mae'r Cennin Pedr a Chrocws wedi eu plannu?

Cofiwch dynnu lluniau o'ch diwrnod plannu i gystadlu yn y Gystadleuaeth Ffotograffydd Diwrnod Plannu!

Cadwch lygad ar dudalen Twitter Athro'r Ardd i weld lluniau o ysgolion eraill: https://twitter.com/professor_plant

Pob lwc! Gadewch i ni wybod sut mae'n mynd!
