In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

This lesson focuses on how materials behave differently as their surface area increases.

Learners develop an understanding of air pressure in two different activities.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

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