Here is a game you can first try on the computer and then set up an experiment in your home. http://www.bbc.co.uk/schools/scienceclips/ages/5_6/pushes_pulls.shtml

Here the student can see how things react to different things or how different things react to the same type of force. Have them conduct a hypothesis (or guess) as to what is going to happen after what they observed in the game. They can plan, conduct, and record their findings for each object and the situation.
