CHEMICAL REACTIONS
October 18, 2018 - Our class learned about what Physical Change and Chemical Change are about through a series of experiments. We learned that a physical change is reversible and no chemical reaction occurs. With a chemical reaction, new substances are formed and the change cannot be undone. We saw demonstrations of experiments with vinegar, sodium bicarbonate, hydrogen peroxide, and citric acid. We also mix water and alka seltzer together to create "popping" reactions. We had so much fun learning about chemical changes.
