Can you think and act like a scientist? Year Five have proven they are real scientists by discovering some of the characteristics of solids, liquids and gases. Through various experiments, they have started to learn how matter can change physically and chemically.
One of our experiments involved finding the boiling point of liquids. Although most students knew the boiling point of water was 100 oC, they did not realize that other liquids have different boiling points. They were surprised to learn that alcohol‘s boiling point was 78 oC, 22 oC less than water. Both substances reached their boiling point within 2 minutes and once they started to boil their temperatures did not increase, no matter how long we boiled them.
Our second experiment involved a chemical change using vinegar and baking soda. We discovered that when matter changes form in a chemical reaction, it looks, smells and feels different. However, it will still have the same mass.
We will be scientists all term long, look for our next blog on how to create secret writing.
