For Science day we did plenty of investigations. We started off by being professional scientists and made our own predictions for a big experiement we were going to do in the hall. We wanted to race some paper fish, propelling them using wind power. We would make 3 fish of different sizes out of paper and then flap our books to see which would travel the fastest.
Here are some of our predictions:
"I think the small fish will go first."
"I predict the biggest fish will win."
We put on our special lab coats and set off for the hall to test our predictions, who would be right? Who would learn something new?
Next we investigated biscuits! Miss Morris asked the question, How do you eat your biscuit?
Well, we had all sorts of ways. Then Marius said he likes to dip his in his milk. Jemima said she lets hers go soggy in her hot chocolate.
Then Miss Morris asked - How long can you dunk a biscuit for? We did not know! 5 dunks, 100 dunks, 10 seconds.
Next she asked - Does it matter if it's cold milk, or hot chocolate? We did not know! You can hold it in longer with milk, No I think you can hold it in longer in hot chocolate. Oh it was Chaos.
So Miss Morris asked - What happens if you dunk it for too long, or the drink isn't the right temperature? We knew this one.
How will we know when to take the biscuit out? Or what temperature to make our biscuits stay intact. The only way to solve this problem is to investigate it.
So we had a rich tea biscuit (other types of biscuit are availiable.), a cup of warm water, a cup of cold water and some paper to record our findings on. So we started dunking and counted how many dunks we could do before the biscuit fell into your drink.
Science Homework
I was super pleased with the standard of science homework that came into school. You lot have been busy at home researching about scientists and trying out some experiments of your own.
We learnt about Jemima's bouncy egg after sitting in vinegar for 24 hours. Fred had made some detail diagrams of the experiements he performed. Amy shared her findings of dunking a paper towel into water and it not getting wet. How? you ask, well by putting the paper towel in a cup, it "stayed dry in a cup under water, the air in the cup splashes the water away". Max M shared his research into Marie Curie, A nobel prize winner from Poland. Florence told us about Sir Tim Berners-Lee, the man who invented the internet. Alex told us about Silvia Earle, who is a real life octonaut, Who has fought to keep the oceans safe from overfishing and polution. He also told us how Jane Goodall "discovered how chimpanzees use tools like twigs". Olivia shared her experiment caled "walking colours", she made purple, by mixing red and blue water, then the colours were absorbed by paper towels to mix in the middle.
Skittles making a rainbow, such a simple experiement which produced so much excitement and wonder. We lined the skittle up around the outside of the plate. Then added some warm water.
Soon the colours started to "melt off the skittles" - says Dan.
We tried the experiment again, breaking the rules we changed 2 variables, we changed the liquid poured on the skittles and the arrangement of the skittles.
We noticed a massive change straight away, "it isn't working! The cold milk won't suck the colours out!" - exclaimed Elizabeth
Or was it? When we looked closer the colour was much paler, the milk was having a different effect than the water did. Then we drew some pictures of our observations.
