It’s simple to teach kids about things that matter if you find the subjects that naturally fascinate them, and solar power is an exciting topic for kids. They enjoy hearing about how our biggest and most powerful star makes more energy is a single second that human civilisations have needed since the beginning of time.
Energy is a subject that children are naturally drawn to. Just try asking a small child how he thinks his body creates the power to breath and walk and talk and run. That will get him thinking, and asking all manner of questions. It’s a good springboard too, onto the subject of how we use energy to power our houses and our lives. You could try talking about ‘clean’ energy and ‘dirty’ energy, or about the type of energy that is running out (fossil fuel, natural gas), and the type of energy that never runs out (solar, wind, wave power etc).
