Help students understand the importance of skin to protect the Human Body from germs. This experiment uses apples and your own students' dirty hands!
Students will help puncture holes into some apples and rub their hands over them. They will observe the amount of rotting, and will also see how rubbing alcohol can be a cleaning agent and protect the apples.
Students will write a report using the Scientific Method. This is a great introduction to younger students to this scientific report writing, which is now a Common Core standard.
