In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

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

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

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.
