This lesson for students aged 7–11 is about how batteries store energy.
Step 1: Create curiosity by identifying a knowledge gap for pupils
A big think about an everyday object – the battery. Finding out what it is that we do and don’t know.
Step 2: Innovate by designing and promoting a new battery
Pupils consider characteristics that are desirable and how these can be measured and compared to other batteries.
Step 3: Interpret and make meaning of graphical representation of data
Pupils review and explain a given graph. Pupils return to their own posters to include a graph that would tell the success story of their battery compared to a different one. (Link to the video clip of racing an electric car against a conventional car.)
Step 4: A plenary compare and contrast
Pupils review two sets of images. How do we currently get a battery to be more powerful? And how do we currently create a battery to last longer? Recognition that battery research is current and essential to the future. (Link to the video clip of the attempt to break the world record for a lemon battery.)
