=> Apple Changes
= This experiment is a quick and easy way for kids to appreciate the chemical changes that happen all around them. All you'll need for this experiment are some apples and a knife.
Cut the apple into sections and have your students discuss what it looks like. Let the apple sit for ten minutes and then examine it again. There's been an observable chemical change while you were waiting, changing the color of the apple! Watch this oxidation video lesson with your students to help them understand the processes that caused the apple to turn brown and provide them with additional examples of this type of chemical change.
