This activity is a field investigation where students design an experiment to determine the coefficient of friction for two contacting surfaces.
Mike Rettberg demonstrates Newton's Laws to his 8th grade science class by rolling a cart containing an egg into a barrier and crashing it. In the process, students learn difficult terms that are reinforced by their discussion of which Laws they are seeing in action.
--In this activity student will create an amusement park ride out of KNEX that displays a certain type of motion. They will describe their ride. They will then place it in the correct spot on the map by writing the name of it on the worksheet. After all groups have their rides labeled on the map- students should fill in the lines section of the worksheet- identifying parallel, perpendicular and intersecting lines.
