This activity book, designed for grades 7 to 12 as part of the TASK CARD series, presents sixteen task card activities in which students investigate how simple machines make work easier. Each module begins with an introduction which provides teachers with a model for effective science teaching, a checklist for lesson preparation, and a list of materials, as well as the logic tree showing how all the task cards in each module tie together. The second part of each module presents teaching notes that contains sections on task objectives, answers, and materials. The last part provides reproducible student task cards, in which the procedures are illustrated with black and white illustrations. In this module on machine, students construct levers from a meter stick and a rubber stopper, pulleys from paper clips and thread, and inclined planes from pieces of cardboard.
Students use spring scales to weigh loads, measure effort, and thereby calculate efficiency.
A reproducible protractor and graph paper are also provided in the supplementary section. ENC does NOT distribute this resource. TOPS Learning Systems 10970 S. Mulino Rd.
