The challenges are designed to find out what the children know.  For example, circuit challenges:

Can you draw a diagram of the following circuits? Don’t forget to use a ruler clearly.

Ready = Make one bulb light up.

Steady = Make two buzzers work.

Go = Make 2 bulbs very bright.  Then, draw a circuit, which makes 2 bulbs very dim.

GoGo = Add a switch that turns off both bulbs.  Is this a series or parallel circuit?

SuperSonic = Add a switch that turns off only one bulb.  Is this a series or parallel circuit?
