For this week's lab, we tried to make a timeline of Geological Time. The above video is my first attempt before we talked about it as a class and I realized I was way off. The attached image of Geological Time shows Earth as a clock which really helped me understand. I had no idea that humans have been around for such a short period of time!
1. What are some Real-Life applications of magnetism? Refrigerators, Computers, Compasses, Northern Lights, Medical Equipment Magnet Lab 1. Ted began with a formative assessment to see what we knew about magnets before we started. The question was what would a magnet interact with? Many of us knew that metals were the answer, but we didn't know what metals specifically. 2. Our lab was set up with a mysterious hovering paperclip. There was a ruler with a large magnet taped to it. Then there was a paperclip that was somehow hovering just beside the magnet, but not actually touching it. The paperclip was attached to a piece of string that was also taped to the table. 3. Our investigation was putting different objects between the paperclip and the magnet to see if they would disrupt the magnetic field. Here are our results: Cardboard: No, does not interact with magnetic field Copper: No, does not interact with magnetic field Lead: N...
Energy in a Pendulum - In a simple pendulum with no friction, mechanical energy is conserved. - Total mechanical energy is a combination of kinetic energy and gravitational potential energy. - As the pendulum swings back and forth, it is a constant exchange from kinetic energy and potential energy. It has the most kinetic energy when it is hanging straight up and down. When it starts to swing, it has the most potential energy when it is at its highest points. Lab For this lab, we experimented with pendulums to see what would affect the pendulum's swing. We tested the length of the string, weight at the end of the pendulum, angle of release, and pendulum design. Surprisingly, the only thing that affected the pendulum's swing was the length of the string. Phet Simulator This is a tool we used to show our findings with technology.
