Toy Cars

Big or small, self-powered or not, let's hear any ways you can think of to use a toy car to teach a science concept.

Speed/Velocity
Have your students practice calculating speed and/or velocity using a variety of wind-up/self-propelled vehicles (or other toys).

Set up a 1 meter (or any other distance) race course and time how long it takes each vehicle to cover that distance. Results can be graphed at the end.

Newton's 3rd Law of Motion
You need a self-propelled car for this activity.

Place a whole bunch of marbles in a shallow pan. Place a piece of cardboard on top of the marbles. Wind up the car, using your fingers to hold the wheels in position until you're reading for it to go, and place it on the cardboard. Release the car... the car will move forward and the cardboard will move backward - equal and opposite reactions. Then talk about why we don't actually see this happening in "real life".

To add to Karen's comment about comparing speed and velocity with a variety of cars: once the children determine the various speeds they could measure the mass of the cars and compare those results with the different speeds and determine if mass and speed are related. Perhaps they could take it a step further and compare the size and shape of the various cars compared to their speeds and see if they are related in anyway. Of course all of this can be put into a chart and then graphed for practice in those areas.
