What should students know as a result of this lesson?
Students will know that speed or velocity is determined by the amount of distance covered by an object in a given amount of time.
Students will know that a reference point is need in order to measure distances and direction covered by a moving object.
Student will know that a battery driven car moves at a constant velocity, however, the overall average velocity of the car will depend on the number of batteries used to power the car.
Students will be able to relate the slope of a line on a distance/time graph to the average velocity of their car.
What should the students be able to do as a result of this lesson?
Student will collect distance and time data for a battery driven car.
Students will construct graphs from their data.
Student will draw the "best fit" straight line to fit the points plotted on their graphs.
Students will be able to describe the motion of their battery driven car.
Materials
For Getting Ready:
One battery powered car per group - inexpensive cars are available at toy stores. Cars are also available through science supply catalogs.
2 batteries - the correct size needed to fit the car
Wire
Wire cutters and strippers (for teacher use only)
Optional - a metal bar cut to the length of the battery size needed
