After looking at the many aspects of the issues behind genetic testing, students are exposed to the pros and cons and must take a stand by writing a position paper. They will view the "Who Gets to Know?" video and/or reading case studies...

A new form of standardized testing? Learners evaluate arguments for and against the use of computer-based standardized tests in schools. They express their views through discussion and explore the views of others through the creation and...

Students investigate the spectroscopic colors unique to elements, and to use this information to create a specific color. They follow a detailed schematic to produce a spectroscpoe to be used in the testing.

How much is too much nitrate in the water? Young scientists discuss the question after they run their own nitrate tests. They also consider sources of nitrates and offer explanations for the levels.

Young scholars predict how many steps they think it will take them to get from the front of the room to the back. They record predictions on paper and then into database and then actually test by walking foot to foot to their destination...

Test your knowledge of tests of significance. A curriculum model for AP® Statistics describes and defines power in terms of tests of significance. It also provides two classroom activities designed to investigate power and how it relates...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

Time to soak up some learning! A hands-on lesson teaches learners about the absorbency properties of substances. They conduct tests by dipping different materials in water to determine which hold water and then complete a handout to...

Use mathematics and simulations to investigate car crashes. IScholars test hypotheses involving car crashes. They collect, analyze, and display data from computer simulations to support or refute their hypotheses.

First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling....

Teams take their cavern designs and build a model from clay or paper mache that can be buried in sand. Testing involves dropping a bowling ball on the buried cavern. Teams dig out their cavern, inspect it for damage, and consider...

Antibacterial socks are a product of nanotechnology. An inquiry-based lesson plan asks collaborative groups to create their own antibacterial socks and then test them against other products on the market. The sock with the least...

Young geologists utilize Moh's hardness scale to help them correctly sort and classify different types of rocks. This lesson has everything you need, including an excellent example of the Mohs' Hardness Test, to successfully implement...

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...

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

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...

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...

Perform an activity on performance testing with a lesson plan focused on the purpose of wheel bearings on skateboards. Learners conduct performance testing on a skateboard to collect and interpret data.

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

Learners perform flame tests on 12 elements. In this flame tests lesson plan, students experiment with elements to observe their visible light spectra emitted as electrons jump from one energy level to another. Learners record their...

Test probability concepts with an activity that asks pupils to first complete a task investigating false positive in medical testing and then to evaluate sample responses to the same task.

It's the moment of truth. Previous lessons in the 24-part series had scholars design and develop shampoo formulas using chemical concepts. The 18th lesson asks them to test the function of their shampoos. To do this, they calculate the...

Students examine the validity of standarized tests. They explore the emotions felt during a test and ways to prepare for a test. Students interview teachers about testing. Students create a student guide to testing.

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.
