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.
Indicators change colour in acids and bases
Use red cabbage indicator to sort everyday liquids into acids, bases and neutral substances.
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.
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.
The Sun drives the water cycle of evaporation, condensation and precipitation
Shine a lamp on water in a covered tank with ice on the lid. Watch evaporation, condensation and rain happen in a small model of the water cycle.
