Today we finished our transfer of energy lesson by having a slider car contest. Students used data from their data tables to achieve random distances. We then explored the concept of newtons as a unit of force. We practiced using spring scales to measure the force it takes to move an object. Next we explored vectors to identify the magnitude and direction of a force. Students used ping pong balls and squeeze bottles to use air pressure to move the ping pong balls through a maze. In the afternoon we learned the difference between speed and acceleration. We used our physic stations with two meter ramps and bubble tubes. We started our investigation of simple machines and mechanical advantage.We focused our explorations using pulleys. Finally, we concluded our day by taking a field trip to the linac accelerator.
