Science Lecture - St. Bede's
Back in January, Year 6 and Year 4 witnessed many science experiments at the St. Bede's Science Lecture. The subject of the lecture was air, giving us a chance to discover more about the different elements that go together to make up the air all around us. This included: nitrogen, helium, hydrogen, carbon dioxide and oxygen.
The lecture involved lots of fun elements, including explosive balloons, dissolving polystyrene and a foam mountain made of hydrogen peroxide!
One fun experiment involved bursting balloons containing either helium or hydrogen. By using a flame to burst the balloon, we got to see whether or not the gas reacted to the flame. Helium had no reaction but the hydrogen made a fireball! It looked incredible in the dark.
We also looked at some elements that had been frozen to very cold temperatures. Did you know that solid carbon dioxide can inflate a glove because of the gas it produces whilst melting? As well as this, we observed liquid nitrogen being used to make gloves, bananas and flowers breakable!
Overall, it was an amazing experience that not only entertained us but taught us as well.
