As if by magic crocus flowers have sprung up all over Wales!

Many opened during the half term holidays, so we should receive a lot more records - now the pupils are back in school.

Unusually, this year the crocus has been reported in Mid Wales before being reported in West Wales. Good news for Ysgol Glantwymyn who normally have to wait the longest for their flowers.

Read my letter to find out how to win a trip and earn your super scientist certificates.

No reports of daffodils yet - but I'm sure we will have a few sightings soon.

My daffodils have started to tilt their heads in preparation to flower. The trees in my garden have started to flower and grow leaves, soon their will be lots of colour in my garden. I can't wait! Lots of signs of spring at St Fagans too.

Let me know how your flowers are doing?

My 1st crocus has arrived! None reported from any schools yet, but I expect the reports to come flooding in this week.

Soon, lots of flowers will appear on the map - so you can watch exactly where the flowers are opening first.

Remember, crocus flowers open mid morning and close towards the end of the day. Download my investigation ideas to test this theory with your crocus flowers.

Don't miss your flowers! If by the end of this week your crocus hasn't opened - please take your pot home over half term. This way you can enjoy your flowers and show your family what you have been growing.

I've not received any questions this week but I've had reports of shoots from St. Mary's Catholic Primary School and St Joseph's R.C Primary.

Please send me pictures of your class with their flowers!

Professor Plant

Slowly, more and more schools are reporting shoot sightings! Cwm Glas Primary near Swansea have reported a few more shoots but still no sign at St. Mary's Catholic Primary School in Flint.

My daffodils are about 10cms tall now and my crocus have just popped through the soil. Even my mystery bulb is starting to grow and there are buds opening on my garden trees. A true sign that spring is coming!

Take a look at the pictures so you can be sure what bulbs you have growing. Send me some pictures of your shoots or how you collect your weather.

Watch your crocus very carefully now because once they start grow they can flower very quickly. As soon as they flower, send in your record so we can see on the map where the bulbs are opening first.

Competitions. Don't for get we have two fantastic competitions this year. The Daffodil Drawing Competition and the Win a trip competition. I've already recieved some very nice drawings from Bishops Childs Church in Wales School. I look forward to seeing some more from other schools soon...

Weather wise it's been very windy for most of us - so please check that your pots haven't fallen over.

Last week Bishop Childs C.I.W Primary asked: "If you plant your bulb at the same time as your partner will they open their flowers at the same time?"  

This is a very good question and if the bulbs were planted at the same time, were the same size and kept in the same conditions then they could possibly open on the same day. But, all the bulbs are slightly different sizes and some may get more water or sunshine - so they tend to open on different days.

Generally, all of the bulbs in one school will open within a week or two of each other. At first, you get a few then the majority will open within a few days of each other, then a smaller number will take a little longer. It's a bit like a race, there will be a few quick ones, a larger group that arrives about the same time then a few slow ones.

In this experiment, we take the average flowering time. So we record each date from each flower then divide it by the total number of flowers. Look at the results from your school last year http://www.museumwales.ac.uk/en/2135/

Ysgol Glantwymyn asks: Ydy'r tywydd yma yn dda?/ Is this weather good? The recent warm temperatures we are having are good - as it is getting our bulbs growing. But, if we have a another cold snap it could be very damaging to our bulbs and slow them down again.

Good reports from schools:

Cwm Glas Primary:  We have got some shouts.

Maesycwmmer Primary School: A very frosty and cold week. We have noticed a few of our bulbs have started to grow. We have our chart ready and we are going to keep personal records of how much they grow each week. This is a great idea!

St. Mary's Catholic Primary School: It has been quite sunny this week and we haven't had a lot of rain.

Many thanks

After all the snow and freezing temperatures, today seems almost hot in Cardiff at 10 degrees Celsius. My bulbs must have noticed too - because they have already started to grow! It really cheered me up to see some life returning to my garden!

Ysgol Porth Y Felin reported: "Now the snow has cleared we can see that the plants are growing. It is getting warmer!" Excellent news! Let me know if the bulbs in your school have started to grow or if you have seen any other signs of spring locally? Send me photographs if you have any.

At this time of year all schools taking part in this spring bulb investigation should be busy collecting weather records for a chance to win a trip and checking your bulbs daily for signs of growth. Please use the resources below to be sure to know what you are looking for and how to record properly.

My favourite question of the week comes from Bishop Childs C.I.W Primary. They asked: "If you plant your bulb at the same time as your partner will they open their flowers at the same time?"  Let me know what you think the answer is and I will reveal next week....

Lots of rain & floods. Unfortunately, many areas of Wales are now suffering with floods, including our museum at St Fagans. Maesycwmmer Primary School reported that they have had "A very wet week!" with over 100mm of rain in one day. Take a look at our recent weather reports sent in from schools to see how much rain they are getting. 

Across the world, many countries are suffering very badly from flooding. In Brazil, Australia and Sri Lanka floods have affected the lives of many people. Although you can't make a direct link between the recent floods and climate change, they do hold a warning for the future: Scientists predict such extreme weather events will increase both in intensity and frequency as the planet warms.

This is why the work that each spring bulb school is doing is so important - so please keep up the good work!
