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...

Examine the science behind rates of diffusion. The video lesson and following interactive activity focus on the molecular components of different smells. Learners monitor the diffusion of each smell as they 'race' through a room.

Learners explore the science of sound by considering the characteristics that make unique sounds. Through an interactive simulation, they adjust tension and string size and view the corresponding wavelength and amplitude changes. 

Who's driving that car? Science is! Through a simulation, learners adjust the magnitude and angle of motion on a driverless car. Two different motions create a resultant motion. Vectors represent the motion and graphs depict the...

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...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

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...

Roller coasters rely on both kinetic and potential energy, but how much total energy does a roller coaster need? Scholars vary the mass of a coaster and the height of the initial hill. Graphs showing the types of energy and total energy...

How can a magnifying glass or reading glasses make things appear larger? Scholars simulate moving a lens closer or farther from an object to observe the resulting image. They also alter the lens focal length. The simulation shows the...

What is the fastest way to get from point A to point B if you are going through two different mediums, such as air then water? Scholars explore the way light travels through air, water, acrylic, glass, and diamond as they answer this...

Touch screens are becoming more common, but how do they work? The simulation shows the electric potential versus system charge as scholars alter three variables. The schematic of the capacitance demonstrates the set up as each variable...

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...

How can we use vectors to determine a person's position when traveling? The simulation offers guided practice at determining the coordinates and the distance between coordinates on a map grid. It reinforces the importance of positive...

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...

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...

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...

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...

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...

How did the stickleback fish, which was once ocean bound, evolve to be able to persist in freshwater lakes? Hear from the scientists who identified the genes and related switches that allowed these survivors to adapt. In addition to the...

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...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

Explore the chemistry behind the airbags that keep you safe in a collision. Using a simulation, your classes find the best gas to use to inflate an airbag. The simulation shows the time it takes to inflate to a maximum volume....
