Inclined Plane - Simple Machine
Investigate how an inclined plane redirects and reduces the force pulling a brick downward, with or without friction. A toy car can apply … a variable upward force on the brick, and the mechanical advantage and efficiency of the plane can be determined. A graph of force versus distance illustrates the concept of work.

Levers
Use a lever to lift a pig, turkey, or sheep. A strongman provides up to 1000 newtons of effort. The fulcrum, strongman, and animals can … be moved to any position to create first-, second-, or third-class levers.
-
Ocean Tides
Develop an understanding of ocean tides by comparing the depth of water near a dock to the positions of the Moon, Sun, and Earth. … Determine the influence of the Moon and Sun on tides, and compare spring tides to neap tides.
-
Tides
Gain an understanding of high, low, spring, and neap tides on Earth by observing the tidal heights and the positions of the Earth, Moon, … and Sun. Tidal bulges can be observed from space, and water depths can be recorded from a dock by the ocean.

Torque and Moment of Inertia
One of the simplest machines is a see-saw lever. Place up to eight objects on the lever at different locations and try to balance … it. Calculate net torque and moment of inertia based on the positions of the objects and the mass of the bar. The mass of each object can be changed, and the fulcrum position can be shifted as well.
-
Weight and Mass
Use a balance to measure mass and a spring scale to measure the weight of objects. Compare the masses and weights of objects on Earth, … Mars, Jupiter, and the Moon.

Period of a Pendulum - Large Angle
Perform experiments with a pendulum to gain an understanding of the period and the dependence on the angular range of the swing. The … gravity, the length and mass of the pendulum, along with the initial angle (which can be very large) can be adjusted, and data can be collected by measuring the time between pendulum swings.
-
Period of Mass on a Spring
Perform experiments with a mass on the end of a spring to gain an understanding of the period during simple harmonic motion. The … gravity, spring constant, and mass hanging from the spring can be adjusted, and data can be collected by measuring the time between oscillations of the mass.
-
Free Fall Tower
Recreate Galileo's famous experiment by dropping objects off the Tower of Pisa. You can drop ping pong balls, golf balls, soccer balls … or watermelons. Objects can be dropped in air or no air, with or without a parachute. The speed of each object is shown on a speedometer and a graph.
