Keeping Healthy

Exercise, good hygiene and a balanced diet are all essential if we want to stay well. This KS2 Science quiz takes a closer look at these three requirements of keeping healthy.

Keeping healthy is about taking care of the body. This includes regular exercise (to strengthen our muscles, keep our weight down and improve our circulation), good hygiene (to prevent the spread of germs which cause disease) and a balanced diet (to make sure that we get just the right amount of all the necessary nutrients). Everyone wants to be as healthy as possible, but do we always make healthy choices?
