Electric Circuits and Block Schedule

We built electric circuits today using batteries, bulbs, and wires. We compared parallel and series circuits and how they affect the brightness of the bulbs. We read and took notes on current electricity compared to static electricity and used a water model to understand a simple DC circuit.

Kilowatt Ours

Students started watching the documentary "Kilowatt Ours" on Friday. Check out their website: www.kilowattours.org/. I am out of town and Megan Clinton is the substitute teacher while I am gone. The film is about energy use in the Southeast. It looks into how coal is mined and used to generate electricity. It investigates greener forms of energy production and ways to reduce energy use. We will finish the movie on Monday. Tuesday will be a day for students to finish up their science posters. The posters will be due on Wednesday, March 9th.

Energy and Speed

Yesterday and today we looked at potential and kinetic energy. We examined how an inclined plane can affect the relationship between force and distance in work being done. We practiced speed equations and did some math calculations. Here is the Speed Practice sheet. People are still working on their science experiments and posters.
