For his science fair experiment, Cole decided to determine how different types, of surface material, affect how fast a matchbox car will go. He chose to use a tile floor, concrete patio and carpet. He used the same car for each of the 20 trails. He measured the distances the car went after riding down a 1 meter-ramp.

What is Cole's test (independent) variable?

What is Cole's outcome (dependent) variable) ?

What must be kept constant (the same) for every trail?

What do you predict will happen and explain why.

Independent variable would be the material used for surface

Dependent variable would be the length of the ramp

The match box must be the same (same weight etc)

Outcome would be
