Year 7 are coming to the end of a topic on renewable energy resources, and today we found out how generators actually work. We know that turbines drive generators to make electricity, but how?
Its all about magnets and coils of wire. Did you know that if you move a magnet near a wire you can make the electrons in the wire move – and moving electrons = electricity! So that’s what we did. We moved magnets inside coils. We tried big and small magnets, thick and thick wire, lots of coils, coils round things, bare coils… and we measured how many milliamps of electricity we could generate. The winners were Tom, Rebecca and Izzy, with a massive (OK, modest) 0.47 milliamps of current. Here they are working on their challenge.
Year 7 students dressed up as the planets in our solar system, leaned lots of facts about their planet, and presented it in assembly on Thursday. Here they are in action. Well done year 7!
Spike and Ed are joint Saturn with a hula hoop ring.
Sid, on the right is narrator and doubling up as Mars.
Jazzy is speedy Mercury , Henry is Earth, Hugo is Mars and Tom is Jupiter with his big red spot.
Bea, aptly, is little Pluto, not called a planet any more but a dwarf planet.
Rebecca goes to maths in her outfit!
In science, Year 7 are investigating fossil fuels and learning about oil and natural gas production which have developed from the remains of plants and animals living millions of years ago. We simulated gas production in the lab. Instead of breaking down dead creatures though, we broke down some Alka seltzer tablets with water. Not quite the same, I know, but the gas bubbled up to the surface in the same way, enough to inflate a balloon. Here we are making our gas!
Year 7 find their vital capacity and peak flow as part of their investigation of breathing and respiration. We used graded volume bags and flow meters to find the volume of air we could fit into our lungs and how fast we could shoot it out. We compared our results to how tall we are to see if there is a link between the two.
