Interactive Primary Bulletin 44     Summer Science Special
An activity to explore portion size          Nutrition
food mass (g) energy (Calories) energy (kilocalories) energy (kilojoules)
apples 385 200 200 840
fried bacon 34 200 200 840
kiwi fruit 328 200 200 840
butter 28 200 200 840

            

  • What do you notice about the mass of the foods?

  • What do you notice about the Calories/kilojoules in each of the foods?

  • What is the difference between serving size and portion size?

  • Look at the nutrition information, particularly the serving size, on foods at home and bring back your findings to class. Would one serving size of cereal be enough for you in the morning? How many do you think you actually use? How many Calories does that much contain?
