  • Connect students to learning and build interest in topic by asking students to brainstorm everything they know about germs in 2 minutes. Share with class and list facts on board.
  • Tell students they will be learning about germs (microorganisms), forms they come in, and what impact they have on our health.
  • Have students count off from 1-6, or divide into six groups.
  • Assign topics to each group as follows:
  1. What is a Germ?
  2. What Do Germs Do?
  3. Bacteria
  4. Viruses
  5. Fungi
  6. Protozoa
  • Have students meet with their groups and use our lesson Facts About Germs: Lesson for Kids to investigate their topic. Instruct each student to take notes on their topic - each student should be a topic expert.
  • When all groups are finished, divide the group by having one member from each group meet, forming 6 groups of students numbered 1-6. This is also called 'popcorning.'
  • Within their new groups, students should take turns teaching others their topic. Have students write notes on chart paper.
  • Circulate the room as students work to support learning.
  • Share work, ask questions and discuss.
