Teacher’s/Leader’s Guide for ® We fight germs! The activities below can help reinforce the material in this Know What? ® workbook when used in the classroom. Many are experiential, helping students work together to better understand issues related to germs and preventing illness and to improve skills needed for success in school and life. You can also use these activities to help students meet select Common Core State Standards for English Language Arts (CCSS.ELA) and for Mathematics (CCSS.Mathematics). Correlations to specific standards are listed below each activity. Visit www.corestandards.org/ELA-Literacy and www.corestandards.org/Math to learn more. Page 2—Germs can make people sick. Your students may be interested to learn more about the size of a “germ.” They may be disappointed to learn that viruses—the germs that cause people to get colds or the flu—are too small to be seen, even under a regular microscope. You can illustrate this in the following way: • Have students look at small objects with a microscope—for example, the period at the end of a sentence. • Tell your students that the germs that can make them sick are called viruses or bacteria, and they come in all shapes and sizes. Some are thousands of times larger than others. But all of them are so small that it would take thousands, or even billions, of them to fit inside the little circle created by a period at the end of a sentence.

There is an effective—and somewhat messy— demonstration you can do with your students to show how germs are spread. Choose one student to be the “germ carrier.” Help him or her to roll a peeled banana between the palms and fingers, and then sprinkle glitter onto his or her hands. Encourage him or her to go about his or her usual activities, touching things and interacting with others as he or she normally would (if the students are with you for just one period, have this student distribute papers or objects among all students). After a while, have students search the classroom, and other places the “germ carrier” has been, looking for germs (glitter). Have them check themselves, too!
