How Does Your Body Process Medicine?
Watch a video that explains the loopy process medicine goes through as it is swallowed and how it reaches the bloodstream.
TED-Ed
How Does Asthma Work?
What triggers asthma? What are the symptoms of an asthma attack? Watch a video that explains how asthma affects the respiratory system and the extra work the lungs have to do when a person is undergoing an asthma attack.

Why Are Sloths So Slow?
With leaves as their main source of diet, sloths don't particularly gain a lot of energy when they eat. But how do they maintain such slow lives? Watch a video that explains why sloths are so slow.
TED-Ed
Why Do Animals Have Such Different Lifespans?
Is it true that larger animals have longer lifespans than smaller animals? Does an animal's habitat help shape the length of its life? And does the ability to adapt and evolve allow living things to expand their lifespans? Watch a...

Evolutionary Development: Chicken Teeth
The development of regulatory genes and the evolution of genes is the focus of a video that shows viewers how closely related we are to not only chimps but to other organisms as well.
Crash Course
Population Genetics: When Darwin Met Mendel
Learners explore population genetics, or how populations of species change over time, leading to evolution with a video that brings together the principles of Mendel and Darwin and explains and models the Hardy-Weinberg equation.
