This document describes a STEM activity involving the development and use of models. It outlines 5 stations for a kindergarten through 1st grade blended learning lesson on force and motion. Each station provides hands-on experiments for students to conduct investigations using scientific practices like developing hypotheses, collecting data, and analyzing results. The goal is for students to understand phenomena like how energy transfers through gears or which surfaces allow balls to roll farther down a ramp. The stations allow students to work individually or in groups to explore concepts of force and motion through guided scientific inquiry.
