In this collection of demonstrations, learners explore Newton's Laws of Motion.

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 lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

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 are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

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.
