Ready, Set, Science!: Putting Research to Work in K-8 Science Classrooms
draws on the teaching and writing of high school physics teacher and science educator Jim Minstrell (for more information, visit http://www.facetinnovations.com).

7 Given the age and experience of his students, Mr. Figueroa made a pedagogical decision to avoid distinguishing “weight” from “mass.” He recognizes that mass is the correct scientific term to refer to the amount of matter something contains and that weight is the measurement of the pull of gravity on an object. Mass is a universal measurement, whereas weight changes with location. His children will learn these distinctions in subsequent years of instruction. However, because his children used the term weight and his goal was to help them understand that weight (or mass) can be measured in more precise ways than sense of feel, he chose to use weight.
8 For some teachers, two volleyballs and a bicycle pump will not be so easy to come by. The activity can be done with balloons as well. In this case, the teacher places two uninflated balloons on a pan balance and adjusts the scale so that they balance. With balloons, the demonstration is a bit more complex because the size of the balloon with air expands so dramatically and creates additional issues relating to air resistance. The inflated balloon will (as the children will likely point out) fall more slowly than the uninflated balloon, even though it is indeed heavier.
