Heat Transfer
Heat Transfer
In this experiment, students will discover the different rates at which materials can conduct heat.
Acceleration and Gravity
Acceleration and Gravity
Students will predict the acceleration of a car on a ramp at different angles.
Popper Energy
Popper Energy
Students will calculate the potential and kinetic energy of a popper toy using simple formulas. 
Pulleys, Work, and Energy
Pulleys, Work, and Energy
In this lab, students will construct a complex system of six pulleys and determine its ideal mechanical advantage.
Force and Inclined Plane
Force and Inclined Plane
Students will elevate the car in two ways: lifting directly and pulling up the ramp.
Similar and Dissimilar Charges
Similar and Dissimilar Charges
Students use a hand-crank Van de Graaff Generator to charge different objects to determine whether they attract or repel each other.
Levers and Balance
Levers and Balance
Students will use the lever system to investigate the correlation force, distance, and torque.
Lab #37.4 Magnetism: Generator Activator
Lab #37.4 Magnetism: Generator Activator
In this activity, students will investigate electromagnetic induction, the principle behind electric generators.
Balloon Helicopter
Balloon Helicopter
Students will observe the motion of the helicopter and study its construction before applying Newton's 3rd Law twice to explain how it moves.
Forces in Equilibrium
Forces in Equilibrium
Students will place three different forces on a washer, and then arrange the forces so that the washer is in stable equilibrium in the center of the table.
Life-Size Collisions
Life-Size Collisions
In this lab, students will observe "explosions," in which one student on a human dynamics cart pushes another.
Circular Motion and the Flying Pig
Circular Motion and the Flying Pig
The pig and its string trace a conical pendulum and allow a perfect opportunity for calculations and measurements of circular motion.
