The Math of Missiles and Rockets
Throwing an object across the classroom is an example of a parabolic trajectory. Students will be able to experiment with a tennis ball, with paper and later on, with a constructed mini-rocket.
Use of Standards Based Grading for an Inquiry Lab on Chemistry of Airbags
