How Do You Measure Radon?

The universe is 90 billion light years in diameter. How do scientists measure something so huge? Space Time explains the process as part of its larger Cosmology playlist. The video addresses the steps to solving the puzzle as well as how...

Young chemists create gold nanoparticles as they learn to measure accurately with the metric system. They create an advertisement for the application of nanotechnology to complete the first lesson in a series of six.

What is a scientist's favorite type of dog? A lab. This lesson includes a lab experiment and a project for young chemists to learn about measurement, including the metric system and nanotechnology. The resource includes grading rubrics...

It seems like a simple process: we breathe in, our nose detects different scents, and our brain interprets the smell. But how does it actually work? How can something smell like vanilla to one person, but like urine to someone else? How...

Injection, taking a pill, or inhaling are the three main ways to administer a drug. But how do these drugs affect the brain? Watch a video that explains how neurons use neurotransmitters to communicate to one another in the brain.

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

Have you heard that humans only use about 10 percent of their brains? Well, don't believe it! After describing the tremendous amount of energy needed to power our 86 billion densely packed neurons, the narrator also explains how our...

Out of all vertebrates, the largest brain when compared to body size belongs to humans. Studying the working brain presents challenges to scientists. Learn about three of the most common tests used to understand how the living brain...

Young scholars investigate the concept of heart rate and how it is effected by environmental stresses like exercise. They conduct research readings and evaluate the data to form a hypothesis to initiate class discussion about the...

What do you get when you mix LiDAR and integrated photonics technology? Why a self-driving car, of course. A fascinating short video describes how light detection and ranging, LiDAR for short, and integrated photonics technologies enable...
