In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
