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.

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.

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.
