Red Nose Day 2021
Volcanic Eruptions!
Dropping a mentos into your cocoa cola or pepsi releases the gas dissolved in it. Gas is much less dense than liquid so all the gas bubbles rise to the top of the bottle and escape, taking some of the liquid with them. This is exactly the same as what happens in a volcano. When the gas comes out of the magma, it tries to escape upwards taking some of the magma with it, forming a volcanic eruption! We tried it with both diet pepsi and normal sugar cocoa cola - our experiments showed the same result.
Circuits Buzzers and Quizzes! In teams we created a circuit that had a buzzer, light and switch to use to answer questions in quiz on Electricity. The Danger Team won!
Children in Need Day - lots of fun and activities

Soap Experiment
Soap Experiment
This week Purple Class have done an experiment to see why it is important to use soap to clean our hands and not just water. We dipped a finger into a bowl of pepper floating in water, when we did this nothing happened except that the pepper stuck to our finger. We then added a drop of liquid soap to our finger and again dipped it again into the pepper and water. Immediately the pepper was repelled to the sides of the bowl by the action of the soap. This demonstrated how important it is to use soap when cleaning our hands!
Purple Class Topic Day off to a Flying Start!
On Wednesday we all designed our own paper aeroplanes. We had a competition with Orange Class to see whose plane went the furthest. Well done to Andre for his plane, which reached a distance of 7.5 metres! Later in the week we also designed tissue paper gliders and tried to see if we could make them go further.
