Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.

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.

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

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

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