Looking after our bodies

Parts with jobs
Your heart pumps blood. Your lungs take in air. Your brain thinks, and it controls everything. Your bones hold you up. They protect the soft parts too. Your skull is a helmet for your brain. Point to each one as you name it. Knowing where they are makes the jobs stick.
Sleep, food, water, moving
Sleep is when your brain files what you learned that day. That is why tired people forget things. Food is fuel, and it is building material too. Water keeps everything working, and you are mostly water. Moving keeps your heart strong. Four simple things. And every one of them changes how well you think tomorrow.
Germs and the twenty seconds
Germs are living things. They are too small to see. They spread on hands. That is why hand-washing works. Wash for twenty seconds, with soap. Soap breaks germs apart, and the time lets it work. Sneeze into your elbow, not your hand. Your elbow does not open door handles.
Rub a little glitter or flour on your hands. Now shake a friend's hand. Look at their palm. Some of it has moved across. Now touch a door handle. Let someone else touch it after you. Some has moved again. That is exactly how germs travel. You just cannot see them. Now wash with soap for twenty seconds and look again. Rinsing with water alone leaves plenty behind. Soap and scrubbing is what shifts it.
