Nurse Dogood has seen an increasing number of children become ill in her school. She has noticed that children rarely wash their hands. She thinks if students would wash their hands they would become ill less often. She wants to test her hypothesis on the first grade class. Are you ready to see if she is right?
During the Clean Hands Quest you will find out as much as you can about proper hand washing and how it keeps a person from becoming ill.
To understand how to prevent illness and spreading germs you will need to find out the answers to the following questions:
What do you use to wash your hands?
How do you wash your hands?
When do you wash your hands?
In order to learn about how to prevent illness by hand washing you will need to study the following websites to gather information:
Lay Your Hands on a
Million (Micorbes)
When you have found the answers to the questions demonstrate to the class proper hand washing technique and what you have learned by answering the following questions:
What do you use to wash your hands?
How do you wash your hands?
When do you wash your hands?
Now that you have demonstrated proper hand washing technique to the class. Check back with Nurse Dogood in two weeks and see if the number of ill students have decreased.
Next compare how long germs can live on hands.
What other ways can you kill germs on your hands, such as hand sanitizers?
How do hand sanitizers compare to soap and water?
Research the current information about hand sanitizers and their use in the classroom
State simple hypothesis about cause and effect relationships between germs and hand washing
