Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Have you ever wondered how cracks form on the sidewalk? Or have you ever thought about what caused the Grand Canyon to be so big and wide? In this video, you and your kids will learn about weathering, the three types of weathering, and how they affect the earth.

Chemical weathering involves chemical reactions within the minerals inside rocks. Water, acids, and some gases contribute to chemical weathering. Mechanical weathering, or physical weathering, is caused by frost or ice, moving water, or the heat of the sun. The most common type of weathering involves water freezing in cracks in rocks. Speaking of the Grand Canyon, scientists believe it was caused by the Colorado River wearing down the rocks over the course of a long period of time. Biological weathering happens when plants and animals, as well as other living things, cause rocks to be broken into smaller pieces. Tree roots or burrowing animals like rabbits are great examples of why rocks might break as these biological influences affect them over time.

The end of this video contains a short review to test your knowledge. See if you can answer all the questions correctly!

We hope you and your student(s) enjoyed learning about how the earth changes in these different ways! If you want to learn even more, head over to our website and download one of our many free lesson plans about weathering, full of activities, worksheets, and more!

Do you know why the heart is so important? In The Human Heart for Kids video, you will learn that the heart, apart from pumping blood, also carries lots of other important things throughout the body. The heart is an organ made up mostly of muscle, and it plays a vital role in keeping you and your body healthy and strong.

The human heart is one the most important organs of the body that is essential for survival. It is part of the circulatory system, which is the body system that carries blood and other substances to and from the heart. The other main parts of the circulatory system are blood vessels, which include veins, arteries, and capillaries. And the heart beats automatically because it's controlled by the autonomic nervous system. In 24 hours, your heart averages about 115,000 beats per day!

So how does the heart work exactly? Well, the heart consists of left and right ventricles at the bottom and left and right atriums at the top. Blood pushes through the atriums into the ventricles on each side of the heart through little "gates" every time the heart beats. These gates basically help ensure the blood flows in the right direction. The blood travels through the different vessels throughout the rest of the body. You can think of blood vessels as little train tracks that carry blood to different parts of the body. The trip for a single drop of blood throughout the body takes only about a minute.

Blood carries oxygen, food, minerals, and vitamins as well, and all these things help your body move, grow, and make repairs. In fact, they even help you think! The stuff in your blood that the body doesn't need gets set out as waste through the lungs, kidneys, and liver. To keep your heart healthy, there are a few things you can do. Exercising will help strengthen the muscles of your heart. Eating fruits and vegetables also helps keep your arteries clear. Drinking plenty of water is also essential because water makes up about 83% of the heart. If you don't have enough water, your heart can become less and less healthy. Finally, remember to move around. Moving around helps both your body and your mind.

We hope you and your student(s) enjoyed learning about how your heart works! If you want to learn even more, head over to our website and download one of our many free lesson plans about the heart, full of activities, worksheets, and more!
