As part of our topic work we have been investigating solar power. We have some small photovoltaic cells that converts light to electrical energy to power a small motor. Before the October holiday we wired up the photovoltaic cells to the motor and got it working. We had a go at wiring it up the opposite way and found that the motor whizzed around in the opposite direction.
Today we worked in our groups to make a working model using solar power. We had some very grand ideas and found with the materials we were using our ideas didn’t always work and we had to make some adaptations – some minor and some major. In the end each group managed to make a model they could be proud of. All the models had a moving part powered by solar power and everyone was very pleased with their afternoon’s work.
Look at our photos. What do you think?
