Bar Code: 1200, 2268





Description: Balancing and Weighing introduces students totherelationship between balance and weight. Experiences with a beambalanceintroduce students to the concept that amount of weight,position of weight,and position of the fulcrum affect balance. Workwith an equal-arm balancechallenges students to place objects inserial order on the basis of weightand to appreciate that weighingis the process of balancing an object againsta certain number ofstandard objects. In the final lessons, students turnto a series ofproblem-solving investigations with the equal-arm balanceand cupfulsof four different foods. These activities provide an opportunitytoexplore the relationship between weight, density, and volume.
