Stem fair project ideas how does mold grow?

STEM questions Which food will grow the most mold? The least? Why? Which environment has the greatest mold growth


 * 1) Select some different foods to test.
 * 2) Have an adult help you cut your samples. You will need 9 samples for each type of food.
 * 3) Take 3 samples of each type of food and cook them. //How might this condition affect how mold grows on the food?//
 * 4) Place each sample into a plastic zip-top bag and seal it. Label each bag appropriately with type of food, the conditions, and environment.
 * 5) Take 3 samples of each type of food and spray lightly with water. //Do you think the wet samples will grow mold more quickly or slowly? Why?//
 * 6) Place each sample into a plastic zip-top bag and seal it. Label each bag appropriately with type of food, the conditions, and environment.
 * 7) Take the last 3 samples and place each sample into a plastic zip-top bag and seal it. Label each bag appropriately with type of food and environment.
 * 8) Place one cooked, one wet, and one dry set of samples for each type of food in the refrigerator.
 * 9) Place one cooked, one wet, and one dry set of samples for each type of food in a dark place like a cupboard.
 * 10) Place one cooked, one wet, and one dry set of samples for each type of food outside in a sunny, warm spot.
 * 11) Monitor your samples daily and make notes on observations. Taking pictures is a great way to track changes in your samples over time.

 hypothesis

Wet samples will grow the most mold, while cooked samples will grow the least mold. Samples left in the sun will grow the most mold, while refrigerated samples will grow the least mold.
