  Living, once living or never alive?

  Living things carry out all the life processes; a thing that shows only one or two, like fire or a car, is not alive

  Check things for the signs of life (moving, breathing, sensing, growing, reproducing, excreting and needing food) and sort them into living, once living and never alive.

  Lighting a bulb: a simple circuit

  Current flows only around a complete, unbroken circuit; more cells push a bigger current

  Connect cells, a switch and a bulb, close and open the switch, add a second cell and break a wire to see when current flows.

  Magnet poles: attract or repel?

  Like poles repel and unlike poles attract; the force gets weaker as the magnets move apart

  Bring the poles of two bar magnets together in different pairs and at different distances, and find the rule for attraction and repulsion.
