This is an entire periodic table, with videos about each element. These videos are chemistry adventures in the laboratory, as well as journeys into the world, to learn more about the unique qualities of each element.
This video explains the law of conservation of mass. Everything in our universe has mass, from the smallest atom to the largest star. How has the amount of mass remained constant throughout existence even during the birth and death of stars and planets?
This TED video lesson examines the two forces that drive both endothermic and exothermic chemical reactions: enthalpy and entropy. There is a short quiz in the Think section and further links in Dig Deeper.
Learn about how stress affects the brain and the resilience scale in this scientifically based video (7:42) created by the Alberta Family Wellness Initiative in consultation with the FrameWorks Institute and the Harvard Center on the Developing Child.
Explore this page of resources about the heart. The diagram has hyperlinked dots that provide additional information. In the top right is a link to a video that explores "inside the heart". At the bottom left are links to quizzes about the heart.
This animated simulation demonstrates the human immune system’s response to vaccination. After viewing the simulation, students can show what they learned by sequencing and labeling the steps in the process.
For several centuries, people thought diseases were caused by wandering clouds of poisonous vapor. This video describes how scientists worked to prove "germ theory" and changed how we see and prevent disease.
This animated video explores the different components of the immune system and how, together, they do their vital work. "Most of the time, you may not even notice it's there, but over the course of your life your immune system will guard you against hundreds of potentially fatal threats."
Watch this animated TED video that describes how your "kidneys balance the amount of fluid in your body, detect waste in your blood, and know when to release the vitamins, minerals, and hormones you need to stay alive." (site)
What goes on inside a body that is chronically stressed? Our hard-wired stress response is designed to give us the quick burst of heightened alertness and energy needed to perform our best. However, when activated too long or too often, stress can damage virtually every part of our body.
Can you grow a human bone outside the human body? The answer may soon be yes. This video explains how bones naturally grow inside the body and describes the innovations that scientists are using to replicate that process in a lab.
This video explores a very interesting theory. In the event of nuclear fallout or another worldwide catastrophe, every piece of digital and written information could be lost. Could all of human history be recorded and safely stored inside our human DNA?
This video tells the story of Henrietta Lacks, a woman whose DNA led to countless cures, patents, and discoveries. Trillions of lab-grown cells called HeLa, after the woman they were taken from, have been the keys to understanding cancer, virology, and genetics.
Do you know your integumentary system? Your skin, which makes up 16% of your physical weight, is the largest organ in your body: laid out flat, it would cover close to 1.7 square meters of ground. But besides keeping your organs in, what is its purpose?
Metabolism is a complex process. This video explores some of its key parts, including vital nutrients (water, vitamins, minerals, carbs, fats, and proteins) and describes two different reactions: anabolic and catabolic.
In this Crash Course video, learn about human metabolism including cellular respiration, atp, glycogenesis, and how insulin regulates our blood sugar levels. What does your body do with the food you eat?
