We all breathe the same air. Literally.
Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub

Take a deep breath. Smell that? It could be a little eau de Einstein. Or maybe a whiff of Cleopatra. Here's an amazing thought: every time you breathe, you could be sharing air with everyone who's ever lived. A few million of the same air molecules that enter your lungs in a lifetime also entered Albert Einstein or Marie Curie's lungs! That's some smart air.

Earth's atmosphere is big, but not as big as many people think. All the air that keeps us alive is just a thin candy shell around our planet. In this episode, echoing the words of John F. Kennedy, I'll show you the science of how we all share the same air. So let's be careful about what we're putting in it!

Students learn how engineers design and construct buildings to withstand earthquake damage by building their own model structures using toothpicks and marshmallows. They experiment to see how earthquake-proof their buildings are by testing them in an earthquake simulated in a pan of Jell-O®.

Hello, friends! Today we are going to learn about fascinating reptiles, those vertebrate animals that move by dragging their bodies or staying very close to the ground. We will discover their main characteristics: their skin covered in scales, breathing through lungs, and reproduction by eggs. We will also learn curiosities about animals like snakes, chameleons, and turtles. Did you know that chameleons can change color to blend in with their surroundings? It's amazing!

What does Newton's last law of motion state? In this Newton's Third Law of Motion video for kids, you will learn the answer to that question and much more. The third law states that for every action, there is an equal and opposite reaction. What does this actually mean?

Think of a rocket. The exhaust from an erupting rocket moves downward while the actual rocket moves upward. Another example is found when a cannonball shoots out of a cannon. The cannonball shoots forward as the cannon moves backward. Because the cannon is so much heavier than the cannonball, it doesn't look like it moves very far, but the reaction is still equal in the amount of force.

One last thing. Have you ever tried to move heavy furniture? You may have noticed that it starts out kind of hard to move. However, as you start to move the heavy object, it gets a little easier. The friction that happens is sliding friction, which is the same sensation you get when you rub your hands together really quickly! Notice how your hands get warm? That's why!

We hope you and your student(s) enjoyed learning about Newton's final law of motion! If you want to learn even more, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

In this video we use GeoGebra 3D from geogebra.org to graph a cone with equation x^2 + y^2 + z^2 = 9 in rectangular and rho = 3 in spherical. Video of finding the equation here: https://youtu.be/BYCdO2vHp00
We use the surface command with parameters for theta and phi (I use t and v). After getting the graph to work we then create sliders for the upper bounds of the parameters and play around with it a bit. Playing around with this kind of thing on GeoGebra is the best way I've found to really learn what's going on.

This physics video tutorial explains the concept of centripetal force and acceleration in uniform circular motion. This video also covers the law of universal gravitation, weightlessness, banked curves with friction, kepler's third law of planetary motion and other stuff. This video contains plenty of examples and practice problems.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This week we explore some of the most powerful artworks ever made, making the case for political art one work at a time. Pablo Picasso's Guernica, Kathe Kollwitz's prints, Kazimir Malevich's Black Square, Iri and Toshi Maruki's Hiroshima Panels, and Martha Rosler's House Beautiful: Bringing the War Home photomontages. What do you think of as political art?
