Everyone knows that you should always wash your hands. But why? And how often? Washing your hands is the best way to prevent the spread of germs. Through this science experiment, students explores which parts of the hand are the most difficult to wash germs off of. Student learned different hand washing techniques and concluded which one is the most effective. Using a special lotion, students can see their germs under an UV flashlight. Students could see the areas that were cleaned thoroughly, and areas that need to be cleaned. Our students had a lot of fun learning about bacteria/germs and learned the importance of washing their hands thoroughly to eliminate bacteria!
