In this lesson students learn about why plants grow fruit. In the activity, Science Fruit or Vegetable, students examine common grocery produce and predict if each item is a science fruit or science vegetable. Then they take a closer look at slices of the produce and search for seeds.

Prep Instructions

Slice Fruits and Vegetables Before Class

We suggest slicing foods before class. We used the foods listed above, but you can use other foods in place of these. Just be sure to include a mix of vegetables that have seeds, such as tomatoes and cucumbers (science fruits), and ones that don’t, such as celery, potatoes, and radishes (science vegetables). If you want to challenge your students, use less familiar produce, such as pineapples, eggplants, and kiwis (science fruits), as well as brussels sprouts (science vegetables).

Place one slice of each type of fruit or vegetable onto a paper plate for each student so that each student will have the opportunity to examine all the produce.

Before students examine the sliced fruit and vegetables and look for seeds, you will show them one whole fruit or vegetable so that they can first make a prediction. So be sure to reserve one of each grocery item to show students.
