There are great resources at www.learner.org on the force and motion concepts and how to teach them. The series at http://www.learner.org/resources/series136.html?pop=yes&pid=1490 includes 8 workshops. They're all good, but 2 and 3 may be the best fit for you. Both include a 5th grade class using plastic cars. Workshop 1 includes a 7th grade class simulating the force of asteroid impacts by dropping balls of different mass from different heights into different materials. Sample all of the workshops if you can to get a feel (or refresher) on the different types and various aspects of force. Workshops 2 and 3 deal primarily with gravitational attraction and mechanical energy. The observable effect is motion. Later workshops deal with magnetic attraction. At least one also shows compression as the result of the application of force. Other observable results of the application of force are heat and noise.
