Explore how bacteria and viruses spread through a population.

• NGSS-aligned with MS-LS2
• Use clear solutions and a color-changing indicator to model a classroom infection
• Record potential infection events and practice contract tracing
• Discuss different types of infections and different detection techniques
• Contains everything you need to complete the activity in 30 min!

Infectious agents such as bacteria and viruses can spread rapidly through a population and cause widespread disease and death. In this experiment, your students will use colored solutions to simulate the spreading of a disease in the classroom.
