What happens to fruits and vegetables that have gone bad, besides becoming too yucky to eat? You're about to find out on purpose!

Think about a time when food in your home went bad.

What did it look like? What did it smell like? Share your story with your parent or teacher.

bad smell

In this lesson, you will conduct a mold experiment. The first thing a scientist always does is to ask a question about what might happen during the experiment. Read this lesson's scientific question:

"How do vegetables change when they go bad?"

During this experiment, you will study how a vegetable changes as it goes bad. Before you begin the experiment, read the experiment description below:

  • You will keep a vegetable in a sealed container for three weeks. During the three weeks, you will study how the vegetable changes over time.
  • You will create a hypothesis (prediction) about how the vegetable will change over time. Your hypothesis should focus on what will happen to the vegetable if it is left untouched for three weeks.
  • With the help of your parent or teacher, work together to create a hypothesis. For example, "If I leave a tomato in a sealed container for three weeks, the tomato will turn blue."

Once you have come up with your hypothesis, move on to the Got It? section to begin the experiment.

Elephango's Philosophy

We help prepare learners for a future that cannot yet be defined. They must be ready for change, willing to learn and able to think critically. Elephango is designed to create lifelong learners who are ready for that rapidly changing future.
