Helo Gyfeillion y Gwanwyn,

Diolch i bawb wnaeth yrru data tywydd ata i'r wythnos ddiwethaf. Roedd rhai o sylwadau’r wythnos yma yn dweud bod y tymheredd yn disgyn, sy’n esgus perffaith i mi siarad rhywfaint am y tymhorau!

Mae yna bedwar tymor mewn blwyddyn: gaeaf, gwanwyn, haf a hydref. Mae hi’n dal yn aeaf ar hyn o bryd, y tymor oeraf.

Mae’r gwanwyn yn dechrau o gwmpas Mawrth yr 20fed (Cyhydnos y Gwanwyn) a dyma’r tymor lle bydd y rhan fwyaf o blanhigion yn blodeuo ac anifeiliaid bach yn cael eu geni wrth i’r tywydd gynhesu. Mae ŵyn bach yn y caeau yn arwydd da bod y gwanwyn wedi cyrraedd!

O fis Mehefin tan fis Medi bydd hi’n haf – y dyddiau’n hir a’r tywydd yn gynnes. Yn lwcus i chi, byddwch yn cael gwyliau hir o’r ysgol!

Bydd yr hydref yn gafael o ddiwedd Medi ymlaen – y dyddiau yn byrhau, y tywydd yn oeri, a’r dail yn troi’n oren, coch a brown cyn syrthio o’r coed. Daw’r gaeaf unwaith eto ym mis Rhagfyr a bydd yn aros efo ni tan ganol Mawrth.

Ydych chi’n gwybod pam ein bod yn cael tymhorau? Beth sy’n achosi i’r tywydd newid mor ddramatig yn ystod y flwyddyn? Mae’n digwydd achos bod y Ddaear yn troi o amgylch yr Haul ar ongl. Mae’r llun isod yn dangos y Ddaear a’r Haul. Mae’r Ddaear yn cylchdroi ar echel (dychmygwch linell yn cysylltu Pegwn y Gogledd â Phegwn y De) wrth symud o amgylch yr Haul.

Mae’n cymryd 365 diwrnod i’r Ddaear deithio unwaith o amgylch yr Haul. Hyd blwyddyn ar blaned yw’r amser mae’n gymryd i deithio o amgylch ei seren unwaith. Felly mae blwyddyn ar y Ddaear yn para 365 diwrnod.

Mae’r llun uchod yn dangos llwybr y Ddaear o amgylch yr Haul. Yr echel yw’r llinell wen trwy’r ddau begwn. Mae’r echel ar ongl wahanol i lwybr y Ddaear o amgylch yr Haul (y llinell wen doredig). Mae hyn yn golygu ein bod ar ongl fymryn yn wahanol i’r Haul bob dydd. Dyma sy’n achosi’r newid yn hyd y dydd. Mae dyddiau byrrach (gaeaf) yn golygu llai o olau a llai o wres, sy’n gwneud y gaeaf yn oerach. Mae dyddiau hirach (haf) yn golygu mwy o olau a gwres, sy’n ei gwneud yn gynhesach!

Mae’r DU yn ‘Hemisffer y Gogledd’ sy’n golygu ein bod yn nes at Begwn y Gogledd nag at Begwn y De. Yn y llun, mae Pegwn y Gogledd (y llinell wen sy’n pwyntio am i fyny) yn gwyro i gyfeiriad yr Haul ym mis Mehefin ac oddi wrth yr Haul ym mis Rhagfyr. Yr ongl hon sy’n achosi’r newid yn hyd y dyddiau wrth i’r Ddaear droi o amgylch yr Haul.

Mae gwledydd eraill yn profi’r newidiadau hyn ar wahanol adegau. Yn Awstralia mae’n haf ym mis Rhagfyr! Ac yng Ngwlad yr Iâ mae’n olau dydd am ddyddiau ar y tro yn yr haf, ac yn dywyll am ddyddiau yn y gaeaf... dychmygwch yr haul yn tywynnu am hanner nos!

Daliwch ati Gyfeillion y Gwanwyn,

Athro’r Ardd

Stane Primary School: It's getting colder and colder every day! Get your hat, scarf and gloves on. Professor Plant: Great advice Stane Primary, make sure you stay warm!

Arkholme CE Primary School: We have had some frosty nights and most of the leaves have fallen off the trees. No change what so ever with the bulbs. Have a good day.

Broad Haven Primary School: Everything was frozen every morning this week. Frost and ice. The birds are hungry they are eating the sunflower seeds of the sunflowers we grew in the summer.

Hudson Road Primary School: Friday was a lovely warm afternoon and we did lots of garden maintenance getting ready for the winter and filled our bird feeders so they will have food in the cold winter days. Professor Plant: That’s lovely Hudson Road Primary. Well done for looking after wildlife in your garden.

Darran Park Primary: Despite the sunny weather, the temperature has been quite cold but not freezing Also the temperature has been quite consistent but it dropped a little bit on Friday. As well, to start the week off is has been raining, nevertheless, the rest of the week has been dry.

Carnbroe Primary School: The weather was dry but cold and damp this week. Although it didn't rain the soil in our plant pots was damp. Professor Plant: Hi Carnbroe Primary, well done for checking whether your plants needed watering. It’s likely that dew or frost has been forming on top of the soil this will be why the soil is damp even though it hasn’t rained.  

Bacup Thorn Primary School: We had a lot of snow Thursday night into Friday. Heavy snow throughout Friday making a wet but enjoyable time at break. We had some very large snow flakes falling.

Yes, you have guessed it, it's time to roll out our annual #MuseumAdvent Calendar at National Museum Cardiff.

Each year throughout December we like to highlight our fantastic collections and spread some Christmassy cheer.

So why not find out what is behind each door of our advent calendar by following the @CardiffCurator Twitter account and see what wonderful suprises we have in store for you behind each one. We have delved deep into our collections to find some great Christmas objects. This year the theme of our advent calendar is lines from Christmas songs and poems. See if you can work out which song or poem each line comes from.

We have started off the calendar with:

Diwrnod 1 #AdfentAmgueddfa: ‘Aur, thus a myrr a gafodd ef, gan ddoethion ddaeth o bell’. Aur Cymru o gasgliadau @Museum_Cardiff

Day 1 of #MuseumAdvent - ‘Five gold rings!’, 5 nuggets of Welsh Gold from @Museum_Cardiff collections

Enjoy!

Our conservation volunteers are helping to get Christmas underway at St Fagans. The first historic building to get the festive treatment was Cilewent Farmhouse originally from Rhaeadr Powys. The display reflects life as it was in the 18th century with most of the furniture dating to 1750. Preparations for Christmas would involve decorating the home with evergreen foliage gathered from the surrounding countryside, such as laurel, ivy, holly and yew. A tradition that has its origins firmly rooted back in our pagan past and continues to this day with the Christmas tree.

The evergreens stand out among the dormant trees in the museum grounds so it didn't take long to gather up enough to prepare the garlands for Cilewent.  We also created a bracket out of 4 sticks of even length (80cm) and to this attached more evergreen foliage and red ribbons. Red berries were very popular, but these dry out and fall off quickly. A recommended technique to help preserve their colour was to store the berries in salt water after picking, we haven't tried this yet, but we'll probably give it a go next year as a flash of red would definitely enhance the overall effect.

The garlands were much bigger than we anticipated and they soon turned into rather unwieldy evergreen snakes, but between us we managed to walk them across the site and secure them to the beams of Cilewent.

If you would like to try this out at home be careful with the holly, it can scratch, not just yourself but furniture and wallpaper as well, so remember to place a barrier of card or fabric between holly and any vulnerable surfaces.

Well, one house done, 11 more to do and only 20 days to Christmas!

As usual in this monthly blog post I’d like to show you some of the objects that have recently been added to the industry and transport collections.

 

The first object this month is a passport issued to Cardiff shipowner Robert McNeil for travel on the continent. It is dated 16 September 1896. Robert McNeil was the founder of the Cardiff shipping company McNeil, Hind & Company.

 

One collection accessioned this month consists of three certificates and two photographs. The certificates were all issued to William Challenger of Hafodyrynys, who was a colliery manager. The certificates comprise a Second Class Certificate of Competency, and a First Class Certificate of Competency both issued under the Coal Mines Act, 1911. This Act had set up a Mining Qualifications Board to make sure that colliery managers, firemen, deputies and other staff responsible for mine safety were suitably qualified and to issue these certificates of competency. The third certificate was issued to William Challenger electing him a Member of The South Wales Institute of Engineers in 1944. Also in this collection, are two photographs (both illustrated here).

The first is a group photograph showing the Llanhilleth Colliery Rescue Brigade, 1923-24, with some wearing rescue apparatus. The photograph is mounted onto card with a handwritten title and list of names. William Challenger appears in the photograph (seated front left) and was the captain.

The second photographs is a group photograph showing "Monmouthshire Education Committee Mining Students' Tour in Lancashire, 1922'. Photograph includes William Challenger (seated second from right) who later became a colliery manager. The photograph is mounted on card with title and names of students printed on it.

As mentioned in previous blog posts, Amgueddfa Cymru holds by far the largest and most wide-ranging Welsh-interest share certificate collection held by any public museum. This month we have added to this collection a share certificate for the Anglo-Belgique Shipping Co. Ltd. This company was based in Mount Stuart Square, Cardiff, and was established in 1916 by Evan Owen of Llangrannog and E.L. Williams of Penarth to take advantage of high war time shipping rates. They acquired the steamer Kyleness which was renamed Cymric Prince. When Williams left the partnership, Evan was joined by his sons Alwyn and Aneurin. Boosted by the post First World War shipping boom, by 1922 they were operating three steamships prefixed Cymric- The difficult years of the late 1920s caused the company to mortgage its two remaining ships to Barclay’s Bank which foreclosed on the mortgages in 1933, whereupon the company was wound-up. The distinctive name suggests an intention to trade with Belgian ports.

 

Finally this month, we have acquired a Tata Steel Port Talbot fortnightly works newspaper. It is Issue 221, and dated 28 April 2016. It would have been given away free to employees at Port Talbot works, and visitors to the plant.

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!
