Wedi’r holl rew ac eira, mae hi’n teimlo’n gynnes yma yng Nghaerdydd heddiw er taw dim ond 10 gradd Celsius yw hi. Mae’n rhaid bob y bylbiau wedi sylwi hefyd – maen nhw wedi dechrau tyfu’n barod! Roedd gweld yr ardd yn dod yn fyw eto yn codi nghalon i!

Adroddodd Ysgol Porth Y Felin: "Wedi i’r eira glirio gallwn ni weld bod y planhigion yn tyfu. Mae’n cynhesu!" Newyddion gwych! Cofiwch roi gwybod i mi os yw’r bylbiau yn eich ysgol wedi dechrau tyfu neu os oes unrhyw arwyddion eraill bod y gwanwyn ar ei ffordd. Anfonwch ffotograffau os oes rhai ar gael.

Ar hyn o bryd dylai ysgolion sy’n rhan o ymchwil bylbiau’r gwanwyn fod wrthi’n brysur yn casglu cofnodion tywydd er mwyn cael cyfle i ennill trip, ac yn cadw llygad am unrhyw olwg o’r bylbiau’n tyfu bob dydd. Defnyddiwch yr adnoddau canlynol er mwyn gwneud yn siŵr eich bod chi’n gwybod am beth i chwilio a sut i gofnodi’n gywir.

Daw fy hoff gwestiwn yr wythnos hon gan Ysgol Gynradd yr Eglwys yng Nghymru Bishop Childs. Gofynnon nhw: "Os ydych chi’n plannu’ch bwlb yr un pryd â’ch partner fyddan nhw’n blodeuo yr un pryd?” Rhowch gynnig ar ateb y cwestiwn a bydda i’n rhoi ateb cywir yr wythnos nesaf... 

Llawer o law a llifogydd. Yn anffodus, mae sawl ardal o Gymru wedi dioddef llifogydd, yn cynnwys ein hamgueddfa ni yn Sain Ffagan. Adroddodd Ysgol Gynradd Maesycwmer eu bod nhw wedi profi "Wythnos wlyb iawn!" gyda dros 100mm o law mewn un diwrnod. Edrychwch ar y cofnodion tywydd diweddaraf o’r ysgolion i weld faint o law mae’n nhw’n ei weld.

Mae nifer o wledydd ar draws y byd, yn dioddef llifogydd mawr. Mae llifogydd ym Mrasil, Awstralia a Sri Lanka wedi effeithio ar fywydau nifer o bobl. Er nad ydyn ni’n gallu gwneud cysylltiad uniongyrchol rhwng y llifogydd diweddar a newid hinsawdd, maen nhw’n rybudd at y dyfodol: mae gwyddonwyr yn rhagweld bydd cynnydd mewn dwyster ac achosion o dywydd eithafol wrth i’r blaned gynhesu.

Dyma pam mae gwaith pob ysgol bylbiau’r gwanwyn yn bwysig – felly daliwch ati!

Yn gyntaf oedd yr eira ac nawr y glaw! Torrodd yr Elai drwy'r dorlan ger Sain Ffagan heddiw. Diferion bychain i gymharu 'da beth sy'n digwydd yn Queensland Gallwch helpu'r rheini sydd wedi eu dal lan yn y llifogydd yn Awstralia yma

I've blogged about it before, but we have started a quilting club here in Oriel 1, St Fagans: National History Museum. We meet every two months on a saturday morning between 11 and 12.30, our next meeting is on 5th March. It's a relaxed and informal session with a mixture of complete beginners and people that have been quilting for a while. Samantha Jenkins is there to help out when we make quilting errors and generally to offer hints and tips.

It's been really lovely and I have started making my own quilt too

It looks pretty garish in this photo so I hope it's going to turn out ok! It would be great if the quilters in the group could email me photos of their works in progress too - my email address is sian.lile@museumwales.ac.uk

The snow and ice has meant that St Fagans:National History Museum has been closed to the public for the last few days and we've had to cancel the Christmas art cart sessions (it happened last year too!).

The plan was to make Christmas decorations, tags, cards and wrapping paper, and these are still things that you could make quite easily at home, and it's lovely and cosy to be inside making things when it's snowy outside!

A really lovely eco friendly decoration is to make strings of popcorn and fresh cranberries - you can put them on the Christmas tree like tinsel, and then in the new year but them outside for the birds! They are super easy to make - take some strong thread (i use embroidery thread), make a knot in the bottom and thread through quite a large needle. All you need to do then is to thread cranberries and popcorn through until you have a long garland - it works best with popcorn that is a little bit stale as this makes it easier to thread.

Paperchains are simple to make and look great too - you can make them out of any kinds of paper, newspaper and magazines look pretty festive. If you wanted to make it a bit fancier, why not paint the newspaper first?

You will need to cut out strips of paper about an inch wide but as long as you would like (the longer the paper the bigger the loop), take one strip and bend it to form a circle and tape or glue it together, with the next strip thread it through your original loop to make a second circle and glue that too - then just carry on until you have made your desired length!

If you want to make your own wrappping paper you could get some brown packing paper and using cookie cutters dipped in paint or carved potatoes, you can print festive shapes!

I've been making paper snowflakes to decorate my house, they look fantastic taped to windows or hanging on a string together. Snowflakes are pretty easy to make but hard to explain so have a look if you can find some instructions on the internet. If you've been to any of the art cart sessions recently, you might be familiar with one of my favourite books The Art of Decorative Paper Stencils , which has really great directions in how to make paper snowflakes and other paper shapes, there is also a second volume out too.

That should keep you busy until the New Year!

The next art club is on the 8th of January at 2pm - please book if you would like to attend - we will be starting a very important project!!

Quilting club is also on the same day at 11am - it's only are second meeting so don't be shy! We would love for some more people to come along (again, please book ahead). Details for both are on our website.

So have a happy and creative holiday and see you all in January

Dim ond wythnos arall o ysgol cyn y Nadolig!

Hoffwn i ddiolch i’r holl wyddonwyr gwych sydd wedi bod yn cofnodi’n ofalus ers y 1af o Dachwedd – dyma’r wythnos gofnodi olaf cyn y Nadolig. Mae wedi bod yn aeaf oer iawn i fod allan yn cofnodi, ac rydych chi i gyd wedi gwneud yn arbennig! Diolch byth, mae ychydig yn gynhesach yr wythnos hon, felly ddylai’r cofnodi ddim oeri’r bysedd cymaint!

Mae llawer o ysgolion wedi dweud eu bod nhw’n poeni am effaith posib y rhew ar eu bylbiau:

"Gan fod y tywydd mor oer, rydyn ni’n poeni na fydd ein planhigion yn byw drwy’r gaeaf " Ysgol Gynradd Gatholig y Santes Fair.

"Mae wedi bod yn oer iawn. Fydd y bylbiau’n tyfu?" Ysgol Porth y Felin.

Rydw i wedi cael sgwrs dda gyda’n Prif Arddwr ni, Juliet, sy’n gweithio yn Sain Ffagan ac rydyn ni’n dau’n cytuno y dylai’r bylbiau fod yn iawn. Bydd rhai bylbiau’n dioddef oherwydd y rhew, ond mae bylbiau cennin pedr a chrocysau yn ddigon cryf - felly dylai’r rhan fwyaf fod yn iawn!

Ar yr adeg yma o’r flwyddyn, mae’r bylbiau wedi’u cuddio o dan y ddaear, felly dyw eira ac iâ ddim mor beryglus ac y gall fod yn y gwanwyn pan fydd y blodau a’r blaenau ifanc i’w gweld. Felly, croesi bysedd :-)

Mae rhagor o gwestiynau ac atebion isod.

Nadolig llawen a blwyddyn newydd dda!
