4th Grade: The fourth graders this week have been wrapping up our unit on magnetism and electricity. The students took (or will take) an open notebook assessment on circuits, magnetism, and electromagnets. For the fun stuff, we are spending the rest of our science time before break designing wind turbines and testing them for electrical output! As part of a teacher education program at Chabot Space and Science Center, I acquired supplies for building wind turbines. The students will be testing different sizes and shapes of blades, and using a multimeter to measure how much electricity is generated when the blades are tested using a fan. So far, it's been great!
- How does motion generate electricity? (The motion can move a magnet in an electromagnet to generate electricity.)
- What blade shape on your wind turbine worked the best?
- Why is wind energy a renewable energy source? (Unlike fossil fuels, wind energy does not get depleted. It is also beneficial because it doesn't release pollution.)
5th Grade: We continue our work on understanding the solar system. We are creating advertising campaigns for each planet, envisioning that tourists may actually be able to visit other planets. Students are making posters and brochures that explain why each planet is unique.
