Fatty foods

Fatty foods on PhotoPeach

MATERIALS:

Brown grocery paper, cut into small squares. Different foods to test: crisps, peanuts, apple, banana, butter, mayonnaise, oil, chocolate, cheese, nuts, popcorn, ham... INSTRUCTIONS:

- Rub each piece of food onto separate paper squares. Count to 20 while you rub, so that you test each food for the same amount of time.

- Label the squares so you remember which food you rubbed on each one.

- Put the papers in order from the most stained to the less.

- Leave them a week (an overnight is enough).

- After a week, put the papers in order again. You'll see that the order is different now.

WHY:

Fat stains the paper while other liquid substances (mostly water) evaporate.
