Title:
Observing the Invisible
Description:
Matter is made of particles too small to be seen. But if we can’t see these particles, how do we know they exist? In this lesson, students will plan and carry out investigations with air and simple solutions to provide evidence that all types of matter are made of tiny particles that are invisible to the human eye. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
