In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

This is a classic exercise for visualizing the scale of the Solar System.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio
