Plannu a mesur

Mae dros chwe fil o fylbiau wedi cael eu plannu ar draws y DU gan y Gwyddonwyr Gwych sydd yn cadw cofnodion tywydd i ymchwilio newid yn yr hinsawdd.

Roedd y tywydd yn ystod yr wythnos plannu yn wlyb iawn, ond er hyn, wnaeth y disgyblion mwynhau garddio yn yr awyr iach. Creodd y disgyblion labeli ar gyfer eu planhigion a mabwysiadu'r bylbiau y bydd yn gofalu am dan wanwyn nesaf. Edrychwch ar rai o'r lluniau a anfonwyd i mewn o ysgolion.

Dechreuodd yr ysgolion i gadw cofnodion tywydd. Maent yn dysgu sut i gofnodi tymheredd a mesur glawiad. Yna, maent yn llwytho cofnodion hyn i'n gwefan gan ddefnyddio eu sgiliau TGCh. Hyd yn hyn, derbyniwyd pum deg pedwar o gofnodion - sydd yn anhygoel!

Hoffwn ddweud helo arbennig i Isaac o Lancashire a ymwelodd ag Amgueddfa Caerdydd dros hanner tymor i ddweud helo. Yn anffodus, roeddwn yn gweithio yn plannu ein Gweirglodd Drefol newydd ar y pryd a ddim wedi cael siawns i gwrdd ag Isaac. Mae'n ddrwg gennym i colli chi Isaac - gobeithio eich bod wedi mwynhau eich ymweliad â Chaerdydd.

Athro'r Ardd.

Eich sylwadau:

SS Philip and James CE Primary School: We're not sure our laminated labels will survive the winter so we wrote our names on the lollypop sticks and on the side of the pots in case the pictures fall off. Any other advice welcome! Here are some comments from the children: "I really liked comparing the size of the bulbs." "I enjoyed seeing the pointy part of the daffodil peeping through the compost." "Putting the soil in and getting my hands messy was the best bit". "It was really cool." Prof.P: Glad you enjoyed planting. Keeping the tags on the labels is tricky. I think what you have done is great. Some schools use a permanent white marker pen to write on the pots.

Kilmaron Special School: This year we have planted our bulbs in 4 different places to see if they grow better at the front of the school or at the back. We have planted some in the bulbs in a new bed and some in old beds to see if the soil makes a difference. Prof P: Great investigative skills Kilmaron - please let us know if you see any changes and if they are as you predict?

Glyncollen Primary School: Our bulbs are in good condition. We enjoyed planting them and can't wait to see them grow. Prof.P: Glad the bulbs are doing well and that you are enjoying the project again at Glyncollen.

Greyfriars RC Primary School: I am really enjoying it thank you for last year. I'm loving the bulbs mine are called Earl and Willum. Prof.P: I'm delighted to hear you enjoyed and are continuing to this year at Greyfriars.

Ladywell Primary School: We are really enjoying looking after the bulbs. We will be a few days behind everyone else as unfortunately they were knocked down and we had to replant the bulbs. We are thankful that you gave us more bulbs because they were destroyed. We are also thankful for including us in the project. Prof.P: Glad you got the bulbs and more importantly that you haven't given up!

Bleasdale CE Primary School: We have been scaring away the slugs! Prof.P: Many gardeners will be very interested to know how you are doing this Bleasdale. Let me know.

Raglan VC Primary: We removed lots of fallen leaves from the top of the pots. No watering required this week.

Ysgol Bro Eirwg: Ar ddydd Mercher cafon ni 19cm o law, sef 190mm - mae'r siart dim ond yn mynd i 100mm! Hefyd ar ddydd Gwener cafon ni 11cm o law, sef 110mm, yr un broblem gyda'r siart! Diolch Athro.Ardd: Llawer iawn o glaw! Wnai newid y furflen we - diolch.

Woodplumpton St. Anne's Primary School: It's interesting to see the difference between the highest and the lowest temperatures in one week. We are very excited to be taking part in the project. We want to know what will happen. Prof.P: Hopefully in the spring you will have some beautiful flowers!

Culross Primary School: We are going to send our weather reports on Monday’s. On Friday the rainfall was 10 mm because it was hailstones on Thursday evening. Prof.P: Wow hailstones already! We had some in Cardiff too - I got soaked!

Burscough Bridge Methodist School: There was a high amount of rainfall this week and due to the weather conditions over Wednesday night the gauges tipped and lost the contents. Prof.P: I use a big lump of clay to help keep my rain gauge in place but most days it should be fine in the soil.
