While we often talk about puberty's effect on the body, what gets overlooked are the fascinating changes that happen in the brain. Puberty, in fact, begins in the brain, and lasts as long as five years. And during this extended process,...

Your personality is often treated as an immutable part of who you are, but while changing it is difficult, it’s certainly not impossible.

In this video Paul Andersen explains how a sine or cosine wave can describe the position of the wave based on wavelength or wave period. A wave function can the position of a wave as a function or the amplitude and wavelength or the...

We still don't know a lot about the deep sea, but thanks to the help of three dead alligators, we know more about the diets of some of the creatures that live there.

Today Hank talks about the deliciousness of alkenes & alkynes, their structures, and how to remember which is which by simply knowing the alphabet. Also, he breaks down hydrogenation, halogenation, polymerization, and...

In this video Paul Andersen explains how beats are created through interference of waves with similar frequencies. The changes in amplitude are caused by destructive and constructive interference. The frequency of beats is equal to the...

The basic physics behind how rockets work!

In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics.

In this video Paul Andersen defines the rate of a reaction as the number of reactants that are consumed during a given period of time. The rate of the reaction can be affected by the type of reaction as well as the concentration,...

Have you ever heard the phrase, 'You look like a Million Bucks?' Well, you do... but you also look like a million particles. In this episode, Sabrina talks to us about matter and particles and that all matter is made up of particles....

In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is...

Conservationist and TED Fellow Moreangels Mbizah studied the famous Cecil the lion until he was shot by a trophy hunter in 2015. She wonders how things could've gone differently, asking: "What if the community that lived next to Cecil...

Hank & his clone Circus Hank explain the power of epigenetics, which studies the factors that determine how much or whether some genes are expressed in your body.

Paul Andersen shows you how to graph data by hand. He explains the required elements of a scatter plot with a best fit line. He shows you how to properly scale and label the axes.

Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes...

You may have heard that using baby talk is bad for children’s language development, but research seems to show the exact opposite.

Mount Everest is unquestionably the highest point on earth, but it doesn't always feel that way.

In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Today we’ll dive further into fluid flow and how we can use equipment to apply our skills. We explain Bernoulli’s Principle and the relationship between speed and pressure in certain flowing fluids. We’ll also discuss how to apply the...

If you live in the Northern Hemisphere, it's almost time for the summer solstice, the longest day of the year! But if all days have 24 hours, what does the 'longest day of the year' really mean? Join Jessi and Squeaks to find out!

The perfect balance of radioactive elements inside planets like ours might make it habitable, and researchers are challenging some ideas about how Mars is losing its water.

Today, glasses help millions of people with poor vision be able to see clearly. But how? Andrew Bastawrous and Clare Gilbert help unravel the answer by explaining refraction - the ability of a transparent medium, like glass, water, or...

In this video Paul Andersen explains how light that is perfectly reflected creates specular reflection. The angle of the incident ray is equal to the angle of the reflected ray. Specular reflection is also known as mirror-like...
