In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

This activity teaches combustion as the interaction of a fuel source and oxygen.
