Machines.
Ron Marson. Task Card Series 22. Canby, Oreg.: TOPS Learning Systems, 1989.
Recommended grade level:
7-8.
During the 16 activities in Machines--which is one of many units in the Task Card Series--students explore simple machines and find that machines save effort but never reduce work. For example, they build a simple lever (a meterstick that pivots on a rubber stopper) to discover how this lever either reduces effort or reduces the distance through which the effort is applied. They evaluate the efficiency of a movable wheel pulley, and they graph how the effort required to pull a cart up an inclined plane changes with its angle of inclination. Students also classify common machines (stairs, scissors, door knob, hatchet) as levers or inclined planes, and build a working model of a wheel and axle.
The activities in Machines require commonly available materials (such as paper clips, thread, cans, and baby food jars). Certain activities can be omitted or sequences changed to meet specific class needs. The unit contains reproducible "task cards" with directions for each activity, a reproducible protractor, teaching notes with answers, and review questions.
