New ReviewSometimes in science mysteries remain mysteries for a long time! The discovery of diffuse interstellar bands happened nearly 100 years ago, yet it took until 2015 for scientists to understand a single band. Pupils learn about the...

New ReviewSpecial relativity relates how things appear when the observer moves. The fourth video in the series on Special Relativity uses multiple examples to demonstrate the principle. It describes the differences when the reference frames move...

New ReviewDo you believe Earth-like planets support life? A video investigation in the SciShow Space series presents information about exoplanets and their characteristics. Scholars learn why these exoplanets may be the best chance for finding...

New ReviewCould there be a planet in our solar system we have yet to uncover? Researchers believe several discoveries in the outer solar system suggest just that! Part of the SciShow playlist, a video presentation discusses these discoveries and...

New ReviewIt's no secret that most of the galaxy is a mystery. Data suggests that the known exoplanets may be most similar to our own neighborhood planet Uranus. Unfortunately, scientists know little about Uranus. The video lesson presenter in the...

New ReviewIs it possible scientists located the first exomoon, a moon outside our solar system? Watch a video lesson to learn why researchers believe they discovered an exomoon and the implications of this discovery on further research....

New ReviewIt turns out there is an interplanetary superhighway, complete with off ramps! A video from the SciShow Space series discusses how using gravity cuts space travel fuel needs to a minimum. Following the superhighway allows spacecraft to...

New ReviewSometimes the best discoveries happen by chance. Scientists did not plan to find gamma-ray bursts, but that doesn't make the revelation less important! A video lesson in the SciShow Space series discusses the discovery of gamma-ray...

New ReviewIs there life on Mars? Is it likely? A video lesson analyzes the possibility of life on Mars. The discovery of water on Mars changes how scientists think about the likelihood of life on the red planet. Part of the SciShow Space series,...

New ReviewThe final video in a series on Special Relativity offers a new hands-on approach to solving the twins paradox developed by Paul Langevin over 100 years ago.

New ReviewSpecial relativity proves that both length and time are relative—but, that's not the complete story. Scholars learn how both length and time have absolute values that don't vary with perspective. The seventh lesson in the eight-part...

New ReviewScientists know things can't travel faster than light speed, so how do scholars add together numbers close to light speed? The sixth video in the eight-part series on Special Relativity answers these questions and more. the narrator not...

New ReviewSpecial relativity provides rules for making time both shorter and longer simultaneously—and does the same for distances. This concept seems confusing, but with help from a spacetime globe and mathematical explanation, the concepts...

New ReviewGenerally, Lorentz transformations require high level math skills, but conceptual understanding can slip just beyond the grasp of many. Using a story and graph about the time and motion of people and cats, viewers of a short video can...

New ReviewThe second video in the series on Special Relativity introduces the concept of perspective, relative distance, and graphing spacetime. Simple illustrations create clarity while describing each concept in depth.

New ReviewOne of the most famous ideas in physics, special relativity, explains the speed of light, the space time continuum, and E=mc^2. Many scholars struggle with the hows and whys of this confusing concept. The first video in a series on...

Carbon is in the air; should we care? Teach the class why it is important to pay attention to carbon levels and how the world population and various countries across the globe affect the carbon levels in the atmosphere. High schoolers...

Did you know that the population is expected to grow to 11 billion by 2100? The resource serves final installment in a six-part series on the global population and its effects. Scholars interpret data from the United Nations about the...

How many people live on the planet, anyway? The first resource in a six-part series covers the topic of the world population. Scholars work in groups to conduct research and make population posters after learning about the global...

Prepare scholars for micro and nanoscale investigations. A lab activity allows individuals to practice their experimental techniques while becoming to accustomed to the smaller scale of the materials. They also make decisions about the...

Explore the meaning of differentiation and integration. A video lesson describes in detail what differentiating and integrating an equation means using the momentum and kinetic energy formulas. Progressing from a linear to a quadratic...

Class members build a machine to demonstrate Lenz's law and help this scientific principle come to life. After building a ring fling machine, instructions for properly operating the machine and a few thought-provoking questions lead to...

Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental lesson. Scholars use spectroscopy with samples of silver solution to...

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...
