Using our senses and caring for our body
Our body has many parts that work together. We use our hands to hold and write, our legs to walk and run, and our head holds the brain that helps us think. Inside the body, the heart pumps blood, the lungs help us breathe and the stomach helps digest food. Bones give our body shape and muscles help us move.
We have five sense organs that tell us about the world. Our eyes help us see, ears help us hear, nose helps us smell, tongue helps us taste, and skin helps us feel whether things are hot, cold, rough or smooth. We must take care of them: never look straight at the Sun, do not put sharp objects in the ears, and wash our face and hands often. Brushing teeth twice a day, bathing, sleeping well and exercising keep the whole body healthy. Following safety rules, like crossing the road carefully, protects us from injuries.
Why it matters
Knowing how our senses work helps us notice danger, like smelling smoke or hearing a car horn. Good habits such as washing hands and brushing teeth keep away germs and tooth decay. Learning about people who cannot see or hear, and how they use Braille or sign language, teaches kindness. These ideas lead to the study of body systems later.
