These are great for science. What child doesn't want to have a play? They can be used for a variety of tasks depending on the sensors that you have available.
You might find that the school has some form of weather sensing station. Can you analyse the data collected? How does this compare to data found elsewhere?

You might have a data logger that does temperature, sound and light levels. Using this you could look at a variety of processes.
 * How fast does a cup of tea cool down?
 * Which sheet of tissue paper lets the most light through?
 * What is the best material for sound insulation?
