This introductory activity gives students the challenge of building a LEGO boat (with limited pieces) that floats and holds the most weight afloat. The students will begin to see how buoyancy works and gain familiarity with putting LEGO bricks in water.

In my physics class, the students modified their "Going the Distance" robots to push on a ball. This was an opening activity for my "Force and Motion" unit. We used some fabric taped to the floor as a hole.

In my physics class, my students create physical pendulums to study oscillations. They use the NXT and a light sensor to test their predictions regarding the period of the pendulum's oscillation
