Each table had a few jars full of substances, for example, baking soda or flour. We would put this in cabbage water, add vitamin C and BOOM! There was an explosion of bubbles. We all learned that this was a chemical reaction, and if we mix different substances together there would be a different reaction, some are unique, some are common! One time when I mixed the mystery substance with cabbage water it suddenly turned freezing cold! My whole class was fascinated. Not only did we get to see the reactions, we all got to make a reaction! I think this was a very important activity because right now we are learning about matter.

Scientist Helen showed us so many experiments like how to mix chemicals and powders and observe the outcomes. She would then ask us what had happened, and why we thought that happened. She later would explain everything. One example of this was when she first put different materials on our desks and told us how to mix them in such a way that there were so many outcomes. Several changed temperatures from warm to cold or fizzed up. Some even changed colour! It was an amazing experience.

We were very excited and curious to learn about science. We began by learning about chemicals and matter, more importantly what they were. After that, we began some real experiments. Firstly, we mixed chemical powders like baking soda, flour and epsom salts with water. The end results were mixtures that were either transparent, translucent or opaque water. We learned about how different combinations of matter molecules make different results in water, as shown. Not bad for a water test, huh?
