This term we are looking at renewable energy so we invited Emma Chittick into our class to work on a few STEM projects linked to our learning. In week 1, the children were challenged to build a wind turbine using Lego. When their structures were ready, everyone had a trial run and were given time to make any necessary alterations to their design. It was very exciting waiting to see if it would turn with the wind from the fan! We measured how much electricity was produced from each design.
In week 2 the class were asked to build a structure with solar panels that would capture natural light and artificial light. This meant that they had to design a structure that could change the angle of the solar panel. Again, they were given a trial run, then a fair test with the same conditions for each group. During our testing, we quickly realised one disadvantage when relying on solar energy. The position of the sun moved as we were testing at our classroom windowsill, resulting in less direct natural sunlight for some of the tests.
Keep a look out for the final challenge next week!
