Wave Interference
Why did the waves get into a fight? They were tired of each other's interference. Scholars observe the wave patterns from dripping water, sound waves, and light waves. They vary the spacing, build barriers, and increase the number of...
PHET
Molecules and Light
Does light affect molecules or does it go right through them? The simulation explores four different types of light: microwave, infrared, visible, and ultraviolet. Scholars alter the energy level of each as it is aimed at seven different...

Gravity Force Lab
Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

Geometric Optics
What would happen if your entire world was flipped upside down? In addition to changing the distance and size of an object, lenses flip the image upside down. The simulation allows scholars to vary the object, move the object, move the...

Gas Properties
We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and gravity in a...

Features of the Sun
An engaging tutorial teaches all about the sun. Learners see its different layers, explore the sun using different filters, and read about its different features. They then choose one feature to research and explore further.

Under Pressure
Do you work better under pressure? Pupils explore pressure when altering fluid density, gravity, container shape, and volume. Units can be converted to kPa, atm, and psi. To finish, scholars describe pressure as a function of depth,...

”Build a Bacterium” Scavenger Hunt
An exciting activity has scholars use cell parts to build bacteria through cooperation with other groups. Each group has some of the cell parts needed, but they must trade with other groups to be able to fulfill their function as a...

Pendulum Lab
How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....
