On Monday 20th of July The Fonterra Science Roadshow came to Pukekohe Intermediate to show their skill in science. Their first presentation was about Carbon Dioxide and how it affected the Earth.
The Science Roadshow team filled up a balloon with Carbon Dioxide, we all had to block our ears as Andrew lit the balloon and it exploded straight away. It was very loud. The second presentation was about sound. We learnt about pitch, frequency and amplitude. They showed us how we can see sound using a fire and a speaker. As the speaker got higher the fire got lower. There were over 20 exhibits to look at after the show.
The Science Roadshow was very cool.
