Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this activity, learners make a photographic image—without a camera!

In this activity, learners use simple materials to create giant bubbles.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity, learners investigate the properties of graphene and graphite.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

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

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

In this activity, learners investigate the effect of heat on a reaction.

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

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
