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.

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

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

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

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

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.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
