Incredible Shrinking Food

Essential Question:

How can we use measurement to observe change?

Objective:

• Children will use a balance or scale to determine the mass or weight of various food items.

Materials:

chart paper

marker

plastic containers with lids

variety of fruits and vegetables, such as cucumber, squash, lettuce, apple, banana, orange, kiwi, tomato, and so on

Methods:

1. Place a collection of fruits and vegetables on the table. Give the children time to share their observations of the items.

2. Cut samples of each item into similarly sized pieces. Using a triple beam balance or a small scale, work with the children to determine the mass of each of the items. Record the data on a chart.

3. As you are weighing the items, verbalize each step you take. Let the children use the instrument, too.

4. Place each item in its own plastic container and cover with a lid.
