This term we have a new topic for writing. We are learning about Chemical reactions. Even though we have just started I already know a lot about chemical reactions. I think this topic is really exciting. This week I learnt that there are chemicals in everything. Putting two things or more together can create a chemical reaction. Such as putting mentos into a diet coke bottle (with coke inside it) can cause the liquid inside the coke to burst out of the bottle and create a little explosion. If you're interested to see what I am talking about, here is a link to the YouTube video of the soda and mentos explosion.
