Fats

Many foods contain fats and unsaturated fats are prone to oxidation. If this happens, they can produce unpleasant and harmful substances which make the food go rancid.

In this paper-based exercise, students look at the structure of fats and the composition of saturated and unsaturated fats in different foods.

The activity also contains charts showing height to weight charts for males and females up to the age of 17.
