Discover the secrets used by scientists to measure mechanical waves. Young physicists learn about measurable wave qualities—amplitude, wavelength, and frequency—by watching and listening to a video discussing longitudinal and transverse...

Scientists know wind is a renewable resource, but is it an efficient one? Scholars adjust the propeller diameter on a wind turbine, the wind speed, and the conversion efficiency within range to learn about the efficiency of these...

How can a pan flute sound one note while we hear a chord? The simulation explores sound waves, vibrations, and harmonics at the molecular level. Scholars control the pipe into which air is being blown, the length of the pipe, and which...

Can you time the speed of your car perfectly so you only hit green lights? The challenge in the simulation is to alter the timing of the lights or the speed of the car in order to do just that. Scholars learn about angular speed as they...

Zap! Ouch! That hurts! But why? And how come people don't experience or respond to pain in the same way? Take a journey on the sensing pathway, from your nociceptors, along your nerves, up your spinal cord, to neurons and glial, through...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

How do we know how long ago a dinosaur lived or an ancient fire pit was used? Scholars learn about the application of carbon dating and half lives to discover things about the past. They adjust the amount of radioactive carbon in the...

How does an airplane control its take off and descent? Scholars explore the forces acting on an airplane and control the angle of attack, wing profile, thrust, and airplane size. They learn about lift, drag, thrust, gravity, and the...

Archery is believed to be one of the oldest sports in the world at more than 25,000 years old—meaning it can teach your classes a lot! Scholars learn about the forces interacting in the archery simulation. They control the archer's...

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.

Find out the science behind ancestry testing! Investigators watch a video exploring how ancestry works before participating in a hands-on group activity. Scholars role play scientists while learning about testing protocols and test...

Don't let your lesson plans go up in smoke—unless they include Boo Bubbles, of course! An engaging laboratory mixes liquid soap and dry ice to create smoky bubbles that burst on impact, making it the perfect way to celebrate Halloween in...

Quiz time! Part eight in a 14-part series about solids, liquids, and gases provides an opportunity to assess individual's learning. The interactive quiz covers the topics of solubility, solubility curves, and diffusion.

The threat posed by super volcanoes is explored in a short video that reviews the destruction caused by Mount Tambora in 1815 and by Peru's Huaynaputina in 1600. Think it can't happen again? The narrator contends that the explosive...

Who says scientists are boring geeks? Certainly not the narrator of a short video who dishes up the scandals associated with Tycho Brahe, a Danish scientist and alchemist (now that's two labels you don't often see together) who used...

If you weren't already blown away by first two installments, check out this clip on how gravity and space-time interact! Our physicist friends, Pontzen and Whyntie, continue their discussion of these motion concepts for your high...

Tamarin monkey language can be categorized by stem upsweep, duration, peak frequency, and frequency change. Although other complex terminology is used to describe the 38 calls of this species, the video is easy to follow and a...

Did you know that some languages have no word for art? The English language does and the narrator of this short video discusses the aesthetic dimension of religious art as it "visually communicates meaning beyond language."
