Need a fun way to teach how germs are spread? Candy Germ Transmission is a fun experiment that can work well with any age group. I use it for high school, but I have friends who have used it in elementary school as well.
The experiment uses two similar candies that are transferred between student pairs. Only a few students are "infected". By the end of the experiment your class can see how germs are spread both directly and indirectly.
Includes instructions, data collection sheet, and teacher notes.
