Have these students shake hands with students, who in turn shake hands with others, until all members of the class have some glitter on their hands. Have students try to wipe away all of the germs. Remember, in real life, germs are too small to see using just our eyes. Development Go to the Georgia-Pacific Health Smart website for a health unit entitled Teaching About Germs . A spray bottle is used to demonstrate how germs can be spread through sneezing.
Students wet their hands and touch a variety of surfaces throughout the classroom.
The resulting wet handprints illustrate how readily germs can be spread through touching. Have students rub their fingers on a cooled slice of potato after they've been outside or in the cafeteria. Then, have students wash hands thoroughly and rub their hands on another potato slice. After several days, have students draw and label a picture the two potato slices in their science journals. Discuss the importance of correct hand washing.
