Describing the Motion of a Battery Powered Car
Abstract: The motion of battery powered cars is investigated as the cars move along a level surface. Time and distance data is collected and graphed for cars moving with one battery and cars moving with two batteries. The pattern of data from both cars produces straight lines with positive slopes on the graphs. Analysis of the lines on the graphs indicate that the cars were moving at a constant speed (velocity) and that the car with two batteries moved with a greater overall speed than the car with one battery. Distance and time data is also used to calculate the average speed of the cars. The average speeds are then compared to the slopes of the lines on the respective distance vs time graphs.
Abstract: This module allows the participant to use inquiry to investigate the science involved in the design and manufacture of an "everyday" product - the athletic shoe.

Abstract: Motion of a car traveling along an inclined plane is investigated. Participants will observe the pattern of water drops left by the moving car. The changing distances between the successive drops indicate that the car was not traveling at a constant speed. The pattern of drops can be used for data collection and graphs representing the motion of the car drawn. Analysis of the graphs leads participants to the conclusion that the car was increasing in velocity, or accelerating, down the ramp.

The Radiometer: Using Inquiry to Teach Energy Conversions
Abstract: A radiometer is made from a glass bulb from which much of the air has been removed. Inside the bulb is a low friction spindle and a rotor with several lightweight metal vanes spaced equally around the axis. When the bulb is exposed to certain energy sources, the rotor turns.
This module allows participants to investigate the motion of the rotor by designing their own experiments and drawing their own conclusions based upon their observations and data. They will then be asked to identify the energy conversions taking place that allow potential energy to be converted into the kinetic energy of the turning rotor.

Based on their findings, participants will create their own liquid density column. Participants will design a lesson they can implement in their own classroom.
Sports Helmets and Impact Testing of Polymers
Abstract: In sports, participants may be subjected to collisions with balls or other people or even crashes on bikes and skate boards. How is it possible for athletes to tolerate such blows and still "remain in the game"? This module allows participants to use inquiry to investigate the materials used to make sports helmets, a modern form of body armor. The participants will perform impact tests on plastic (polymer) samples by dropping a plumb bob from differing heights onto to the samples. The test, modeled after actual industrial testing methods, will measure the brittleness of a material that has been subjected to an intense blow. Both "hard" plastics that may be used in the outer shell of a helmet and foamed plastics that can be used for the inner lining of the helmet will be tested. The participants will use data gained from their tests to determine which plastics they feel are most suitable for usage in a helmet.

Abstract: As a result of the presenter-conducted discrepant event demonstration, teachers will pose a problem. They will formulate their hypotheses, conduct experiments, and report their findings. Since it is unlikely that the teachers will be able to reproduce the outcome of the demonstration, it will be pointed out to them that very often scientific investigations do not lead to "answers". We suggest that this experience follow the lesson: "Miracle Fish: Designing a Scientific Investigation" found at... This lesson gives teachers an opportunity to experience and discuss how a demonstration can be a vehicle for investigative science activities.

You are What You Eat!
Abstract: As a result of the presenter-conducted module, participants will construct a simple calorimeter. Through experimentation and simple calculation, participants will determine the number of calories in a sample of food. Through the use of the Internet, participants will plan a meal and calculate the number of calories the meal contains. From that calorie count, they will devise an exercise program to "burn off" the calories consumed. Participants will design a lesson they can implement in their own classroom.
Abstract: This module provides participants with an activity that can be used to teach their students both physical and chemical changes as well as demonstrate exothermic and endothermic processes. This simple experiment yields many interesting results. As baking soda and calcium chloride dissolve in a water-based indicator, temperature changes occur. As the dissolved chemicals mix in solution, carbon dioxide gas is created and the Ziplock bag swells. The gas mixes with water to produce a weak acid that changes the indicator color from red to yellow.
