Friday 15th March
We started our second day of science week with a fascinating talk in the hall from an embryologist. She told us all about her job and how she helps people to have babies. She showed us photographs of her lab and explained that the lab was quite dark because the embryos are very sensitive. She explained the qualities an embryologist needs such as good observation skills and she explained that we can start to develop these skills at school. Finally, she showed us a time lapse video of an embryo splitting up into cells and beginning to grow. It was really interesting!
Each class also had a session in the forest. During this session, we toasted marshmallows and had hot chocolate. Also, we had a treasure hunt where we had to find chocolate coins which were hidden. There was a hammock for people to sit in, there were small blocks of ice to sculpt and we had trowels to dig and then magnifying glasses and identification cards to see what creature we had discovered.
As today is outdoor exploration and discover day we have spent the day carrying out investigations around the school. Some children have been investigating the ages of different trees. We did this by measuring the circumference of the tree. We were then told that for every 2.5cm of the circumference it represented about one year of growth so we divided the circumference by 2.5 to find the rough age of the tree. We were set a challenge to see who could find the oldest and youngest tree in the school.
Other classes carried out an investigation using small canisters of warm water. The aim was to keep the water as warm as possible for the longest length of time. Some of us placed the canisters around school thinking about which places would be the warmest, others wrapped the canisters in different types of material. We then took the temperatures of the water to see which places or materials had kept them warm for the longest. Some of us then plotted line graphs to compare the findings from two different canisters and decide which material kept the water the warmest.
Day Three: The World
We thought about how we use plastics in our lives - at home and at school - then found out about what happens to some plastics once we have finished with them. What we discovered was shocking! A lot of plastic waste ends up in the oceans and can form 'trash islands' and be eaten by or kill wildlife. It is thought that more that five trillion pieces of plastic are in the world's oceans and it can take many years for it to break down. Experts think that by 2050, the amount of plastic in the ocean will weigh more than the amount of fish in the ocean.
We investigated how we can reduce our use of single-use plastics and made plans for how we can each make a difference and help to stop this happening to our world. Easy things to do are: reuse water bottles rather than buying them each time; ask not to have a straw in drinks when you are out; recycle everything that you can.
These websites have lots of interesting information and advice about the effects of single-use plastics and reducing plastic waste.
We also found out about a famous explorer named Ernest Shackleton, who attempted to cross Antarctica in
In the afternoon, we listened to 'Space Oddity' by David Bowie and analysed the lyrics. Lincoln and George like listening to 'old' music so they were really good at it!
We also had a visit to the 'Wonderdome ' which was set up in the hall. It was really dark inside and we watched a film all about space. The film was projected all around the dome. Here are some of the facts we have learnt.
"Mars used to have lakes and oceans. They have disappeared and no one knows why." Abdalla
"There's more water on Europa (one of Jupiter's moons) than there is on Earth." Lincoln
"It would take around 20 years to get to Pluto and back." Stella
"Jupiter has 67 moons." Anjali
Friday and Comic Relief!
After all the fun of Science week, we had even more fun on Red Nose Day. We were allowed to dress in red and bring in a £1 donation. We had a Y6 cake sale at playtime.
Our sale made £66.15. All the proceeds are going to be added together with the other year group collections so that we get a grand school total. Look out for the final total in the school newsletter and on the website.
Thank you to everyone (children, staff, families and visitors) for a fantastic, fun-filled week!
