More than half of the human body is made of water. We simply cannot live without it! Water carries oxygen and nutrients throughout our bodies, helping us stay healthy and energetic. Water keeps our bodies at the right temperature, not too cold and not too hot. That's why we need to drink lots of water every day to survive. However, only a small amount of Earth's water is safe for drinking. In this episode of N*Gen, we explore different types of water, from dirty puddles to saltwater, and learn how to test if it's safe to drink. Get ready for some fun experiments you can do at home that show you how to remove dirt, salt, and bacteria from water, making it pure and safe enough to drink. Water is essential for life, so make sure you know what you're drinking!
