Humans: growth, food and keeping healthy

Growing and changing

Humans go through the same stages as other mammals: baby, child, teenager, adult, older adult. Growing is not only getting taller — it includes learning to do things the body could not do before.

A balanced plate

Different foods do different jobs. Carbohydrates (rice, bread) give energy; protein (fish, eggs, beans) builds and repairs the body; fruit and vegetables give vitamins that keep the body working; water is needed for everything. “Balanced” means enough of each group, not none of any group.

Exercise, sleep and hygiene

Exercise makes the heart and muscles stronger; sleep is when the body repairs itself; washing hands stops tiny living things getting into food. Each of these has a reason, and the reason is what earns the mark.
