Instructions 

Keep one plank bare. Cover other planks with different materials. Create a ramp  by propping up one end of the plank. Let children roll toy cars down the ramps to explore differences in speed and distance traveled. Ask children to make predictions about how different materials affect speed and distance.

The children were using planks for building. Knowing the children were also interested in vehicles, the educator connected the two interests and built a ramp. Children then explored different ramps, indoors and outdoors, in all kinds of weather.
