How much sugar?

Do you know how much sugar is in the drinks you drink or give to your children? We set up an investigation to find out how the amount of sugar differs between common drinks.

We decided to calculate the amount of sugar in the full bottle or container rather than for the same amount of the drink as most people would drink a whole bottle, but as an alternative you could calculate the amount of sugar per 100ml or 200ml of each drink.

  • Use the information on the side of the bottle to calculate how much sugar the drink contains.
  • Weigh that amount of sugar.
  • Compare the sugar found in different drinks.

Extension Tasks

Calculate how many cups of sugar you would need to drink to consume the same amount of sugar as one bottle of Ribena. We used this great balance from Learning Resources.
