In this section you will hear about several lessons on various aspects found in the topics on Energy and Forces. There are lessons on forces, lessons on energy change and lessons on electricity. The teachers also describe how you could use PowerPoint and spreadsheets in this topic. You could also use the dataloggers to collect information about the movement of the toys. There are various ways you could use toys in this topic. For example you could ask the children to investigate the motion of toy cars. How far do penny racers travel? Does their shape make a difference? Or they could investigate the effect of the number of turns needed to propel wind up toys. Does a toy wind up helicopter need more turns than a wind up train? Why? Does a wind up train travel twice as far if it has twice as many wind up turns? Or they could build paper/model aeroplanes and conduct investigations to identify the 'best' plane.
