Bite 3 - Food Safety and Science


3a. Green fuzzy stuff
Project skill: Storing fruits
Life skill: Using scientific methods

1. After two weeks, what happened to the fruit in the bread sack that was stored in the refrigerator (control)?
Nothing - it looks the same but possibly a bit drier.

2. What happened to the fruit stored in a warm, dark, place (variable)?
Fruits look like blue-green fuzzy balls. It is actually a colony of millions of microorganisms growing together, called penicillius. This mold is the one from which scientists make penicillin, the medicine that fights infection when the body is sick.

3. How does this experiment suggest the best way to store fruit?
In the refrigerator. Cold temperatures slow down the growth of molds and bacteria. Molds grow fast in warm, moist places.


3b. Make your own yogurt
Project skill: Making yogurt
Life skill: Processing information

3. Besides eating the yogurt you made, how can you use the yogurt as a substitute for other dairy products?
Yogurt can be used instead of milk or cream in gravies and ice creams; instead of sour cream in dips and dressings, such as on gyros sandwiches, or as a topping on cheesecake; instead of ice cream in milk shakes; and instead of mayonnaise or salad dressing in fruit salads and lettuce salad dressings.


3c. Reheating leftovers
Project skill: Reheating leftovers
Life skill: Preventing illness
