Simulations of common biotechnology techniques performed in a laboratory setting. Learn how to complete these techniques and what task they are used for in the lab.

A collection of simulations on nano materials, nano applications, and machinery at the nano level. Students can learn about carbon nanotubes, material strength, a conveyor belt made on the nanoscale, and sputttering.

Explore molecule shapes by building molecules in 3D. How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare...

A collection of simulations representing concepts discussed in a mechanics unit of physics.

View a simulation of the movement of water after a dam is destroyed.

Adjust the rotation in this simulation to see how particles of fluids move.

Adjust the peeling force in this simulation to see how the van der Waals bonds break while peeling a piece of duct tape off of a surface.

View this simulation to observe how water molecules move through carbon nanotubes.

Adjust the mass of one of the balls to see how the other objects are affected in the animated Newton's Cradle.

Experiment to see how air resistance affects the periodic motion of a mass on a spring.

Observe how friction affects a mass connected to two springs that are on opposite sides of the mass. Create a graph while the friction is on or off.

See how motion is converted and the energy associated with the motion is used to do work.

View the conversion of linear motion to rotational motion.

Adjust the elasticity and mass of a rope suspended between two points to see how it will be affected by gravity.

Watch how the placement of two weights attached to a chain on different sides of a pulley affect the movement of the system. You can adjust the heaviness of the weights.

Watch as two particles move through a confined area. The emphasis is on their motion in a straight line until they encounter a barrier and are reflected off in a different direction.

View several examples demonstrating that rotational motion may be transformed into straight-line motion.

View a simulation that shows the reaction to a cart on wheels carrying a swinging pendulum.

Explore how friction between a surface and tires affects the movement of a bicycle.

View a simulation that converts rotational motion into waves.

View a simulation of water moving over the top of a water wheel and causing it to move demonstrating the conversion of energy.

View a simulation of water flowing under a wheel that causes the wheel to rotate. Energy from the water is transferred to the wheel.

View the example that shows how a cycloid is created.

View a hypocycloid being created in this simulation.
