Vitamins and Minerals for Kids | Learn the difference and why they're important Teacherflix 10 Views • 2 years ago

What exactly are vitamins and minerals? Many people think these two substances are the same, but they are not. But they are both important to keep our bodies strong and healthy. Vitamins are organic substances, meaning that plants and animals produce them. Minerals are inorganic and come from the soil and water. Then they are absorbed by plants or eaten by animals.

Vitamins are divided into two categories—fat soluble or water soluble. Which category a vitamin falls into depends on whether it dissolves best in fats or in water. The fat-soluble vitamins can be stored in the body, but the water-soluble vitamins need to dissolve in water before the body can absorb them. In addition, the body can’t store water-soluble vitamins. For this reason, we need a fresh supply of water-soluble vitamins each day.

When it comes to minerals, our bodies cannot break down or change them. Minerals can, however, form part of the structure of bones, teeth, nails, muscles, and red blood cells. There are several minerals the body needs. Calcium is one of the most common minerals. Our bodies need calcium to build and protect bones and teeth, support our muscles, and help with blood clots and nerves.

We hope you and your student(s) enjoyed learning about these essential nutrients! If you want to learn even more, head over to our website and download one of our many lesson plans about health, full of activities, worksheets, and more!

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.

For free. For everyone. Forever. #YouCanLearnAnything
