Mrs Heelan’s class constructed spaghetti bridges as part of Science Week. They had to be 30cm long and be able to support a weight of 200g.
They created some excellent bridges!
Third/Fourth class looked at the use of arches in construction through studying the strength of eggshells. The class used maths books to test the strength of 4 egg shell halves. An amazing 14 books were stacked on the shells before they broke!
In third/fourth class the pupils investigated how sound travels through different materials. The experiment involved using a clothes hanger and string to tap off objects and observe the sound made. The pupils then repeated this while holding the string in their ears. The experiment produced some interesting results!
This week we did some experiments. We did an experiment with Coke and Mentos. We found out that by putting Mentos into Coke, you can make an explosion!
It exploded because when you put in more sugar, it makes more bubbles and the more bubbles you get, the bigger the explosion you get. The bubbles push the liquid out of the bottle.
We also did another experiment. We showed that air pushes an object in the opposite direction. Check out our photos of the air balloon race.
We thought that it was very exciting. Maybe you could try this at home. If you are trying it at home, you will need; two chairs, a balloon, string, a straw and tape. Race your friends to see whose balloon is fastest!

Third/Fourth class experimented with water and how changes to temperature and density can affect it.
Buoyancy in fresh water/ salt water.
Analysing the difference between the amount of sugar which can be dissolved in cold water vs warm water.
