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.

Build a house you can fit inside, using cardboard tubes.

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

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.
