In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this activity, learners explore clouds and how they form.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

In this activity, learners electrically plate zinc onto brass objects.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
