Reflection: Intrinsic Motivation Inertia is Latin for "Lazy" - Section 2: Inertia Activities

 

I love this activity because students love this activity.  When I tell them to clean up, there are groans of dismay as students do not want to stop.  The best part is, it connects well to the opening concepts that persist for the entire unit!  Here is a slow motion video of the 2014 record breakers.  My student's current record for the most in one shot is 32 nuts.  

A common student misunderstanding is that inertia is a force, which is why I ask their option on the inertia activity sheet.  About half of the students think that inertia is a force.  On the activity sheet, I am mostly looking to see that students engaged in the activity and filled in their best guesses.  One this student sample, I see that the student did not answer one of the first questions and they lost points for that.  However, this is one of the few students who correctly stated that the hover puck did not need human intervention to maintain motion because the fan removed the force of friction which would normally cause it to stop.

Inertia is Latin for "Lazy"

Unit 1: Forces in One Dimension
Lesson 1 of 11

Objective: Students explore the concept of inertia, specifically that an object in motion does not require a force in order to maintain its motion.

Big Idea: Newton's 1st Law of Motion states that an object in motion maintains its motion and an object at rest remains at rest unless acted on by an unbalanced force.
