Speaker's notes to explain the slide:

This is the Ramps domain. Children have to construct, a set of contrasting ramps. They can vary each of the dimensions shown here. Then they can choose which of two kinds of balls to roll down the ramp.

This is a TERRIBLE experiment. Everything varies. If you wanted to know if the surface made a difference, you couldn’t tell for sure from this experiment.
