Rutgers has Evaluation Skill w.s. on Forces and other mechanics topics. Review the presented situation, and determine alternate solutions, the possibility of the presented solutions bein correct / in-correct.

ppt slides of multiple representations of force problems. students analyze a graph to produce #'s, analyze #'s to produce an equation, analyze an equation to produce a graph... Good stuff. They have these materials in multiple topic areas.

Surprising Data. The Rutgers folks provide a situation, ask for a prediction, then let you view the experiement. Student then resolve the issue (if the results conflict with obserations).

ASU's Modeling materials in Mechanics are available for free to anyone interested. Their materials below are for:

1- Author, Paul Lulai plulai@stanthony.k12.mn.us
2- Lab Type: Structured, Engineering
3- Students use a force sensor and motion detector. The measure force of tension on a material (for me, printer ribbon or very lightweight fishing line) and the elongation of the material. A graph of the materials properties is produced. It plots Stress (force / area of material) vs Strain (elongation / original length). A materials Young's Modulus and maximum tensile strength can be measured. My students then use this data to determine how many loops of the material they need to hold up a lab-mate. Force Investigation:

1. Author: Brittany Reed brittany_reed@bullis.org
2. Lab type: Inquiry/investigation
3. I use this lab on one of the first days that I begin talking about forces and different types of forces. Students investigate how Normal, Friction, and tension forces change in different situations.

Students determine the minimum tensile strength required for a leash to be used on flying pigs. Students also find net radial F (aka centripetal), net radial acceleration, tangential velocity, angular speed and so on.

Students are led through splitting the tension into x- and y-components and compare a theoretical velocity to a measured velocity. Honors level or AP B level.

A toy flying pig is a canonical pendulum. By measuring the mass of the pig and the radius of the pendulum, one can determine the (theoretical) equilibrium speed of the pig. This can be compared to the actual speed. I use this Lab in AP-C, but it could also be used in an Honors course.

First Law Day -- activities to illustrate the First Law.

This is a pretty straight-forward lab that uses the rotational apparatus from Pasco, but could be easily modified, and the goal is to determine the rotational inertia for a variety of objects.

Equilibrium & Torques If you are a risk taker, give the following web site with no instructions other than to turn in a drawing or printout of the end. Tell them they will know when the end happens. I've done this two years in a row. http://www.vectorpark.com /levers.html Suggested by dcarr; posted by Bill Taylor

Equilibrium & Torques I give my students a meter stick, a loop of light string with which to suspend it from a pole stand, a standard mass (200 grams works well) and another loop of string to use in suspending that from the meter stick. The task: determine the mass of the meter stick. I let the kids check their result with a balance scale after they have finished their calculations. Usually, they find the task hard and do much more complicated calculations than are needed! Suggested by Helen Young; Posted by Bill Taylor

The Force Diagram - Instructions to students on how to do Force Diagrams and begin force / motion problems

- Four different lab stations that investigate accelerated motion in an elevator, atwood's machine, and inclined plane. This lab may take more than one day, depending on the length of the class period. This is an open-ended lab, with no specific procedure listed.

The West Point site has a bunch of nice activities

: Lab in which students calculate the coefficient of friction (static and kinetic) for the rubber stoppers on the TI calculators (incomplete, needs finishing). Modified from unknown source.

Lab in which students use a java simulation to investigate the difference between static and kinetic friction and to calculate frictional coefficients between objects. Submitted by Brittany Reed, brittany_reed@bullis.org

Friction using Phet Force and Motion:V. Risk
Students work with friction calculations and concepts before doing the hands-on friction lab.

. Here's a recently created coefficient of friction lab. I've never tried it but it principle I think it will work. We'll see shortly. Submitted by: Mark W. Hossler, mhossler@landmark-cs.org
