Circuit boards

Today the science people made a circuit board with Jenni. There were three groups doing it but only two groups worked, mine was one of them. My groups one lit and then went pop! We needed 8 batteries, some wire, a jar, pie tins, 3cm of paper roll and leads. The people in my group were Finn Alex and myself. Every teacher looked at ours and the teacher took photos.      

Enviroment

Today Anastazia from Southland Environment  came and taught us about the environment. But after we realized that most things we have done in the past affected the future, so next week we are going to do a project to help stop the people realize their mistakes. Because we want more people respecting Invercargill not just some but everyone.  She told us about how we can help protect nature and get rid of the pests that try and harm nature.        

Chemistry

Today I did chemistry, it was pretty cool because we made some Elephant Toothpaste.  When we put yeast in and it rose up up up.  It looked like it was toothpaste because some of it had stripes in it.  Mine didn't.  I did yellow and green food colouring but I over did my yellow so I only got yellow.  We saw this video of some chemistry it was outside so they put all the stuff that we did except food colouring and it exploded in to the air because they used more hydrogen peroxide than us.
