On Friday March 6 our class had some special Science demonstrations put on by our very own principal, Mr. Kristof. Before he was our principal, he was a chemistry teacher so he knows a lot about chemicals and showed us some cool things.
We found out that everything is made up of atoms and he was able to change some of the atoms in the chemical he brought to make something else. We learned that you can see a chemical change by its colour, by a sound, by fizzing (the creation of gas) and by the creation of heat. You might want to check out these two websites for more information.
