Ingredients in your shampoo are toxic enough to kill plants. The 16th installment of the series of 24 tests the toxicity level of various concentrations of SLS, a chemical found in nearly all shampoo. Learners prepare percent solutions...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Three, two, one, blast off to a better understanding of force and motion with this exciting science lesson! Beginning with a discussion about rockets and gravity, young scientists go on to complete a series of worksheets about net forces...

Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

Students prepare a test solution whose color changes when an acid or a base is added. They determine whether various household substances are acids or bases and look for patterns in the results. Students determine how their test solution...

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...
