4th Grade Physical Science

Masses and SpringsHang masses from springs and adjust the spring constant and damping. Transport the lab to different planets, or slow down time. Observe the forces and energy in the system in real-time, and measure the period using the stopwatch.

Forces and Motion: BasicsExplore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Energy Skate ParkLearn about the conservation of energy at the skate park! Build tracks, ramps, and jumps for the skater. View the skater's kinetic energy, potential energy, and thermal energy as they move along the track. Measure the speed and adjust the friction, gravity, and mass.

Pendulum LabPlay with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, the strength of gravity, and the amplitude of the swing. Observe the energy in the system in real-time, and vary the amount of friction. Measure the period using the stopwatch or period timer. Use the pendulum to find the value of g on Planet X. Notice the anharmonic behavior at large amplitude.

Balloons and Static ElectricityGrab a balloon to explore concepts of static electricity such as charge transfer, attraction, repulsion, and induced charge.
