In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

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

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