About this worksheet

What students practice

Students use test data to compare models of an animal carrying pollen between flowers.
Students develop a simple model showing how a bee moves pollen from one flower to another.
Students identify what a pollination model represents and how it can be improved.

How to use

Read the garden notes together and review the graph scale. Have students use the evidence to answer questions, then draw and label their own pollen-carrying model.

Under the Cucumber Arch

Cucumber vines climb an arch in the school garden. Zuri watches a bee visit their yellow flowers. Bees visit flowers to get food. As a bee brushes against a flower, pollen may stick to its body. Some pollen may rub off when it visits another flower. Moving pollen to the right flower parts can help a cucumber plant make seeds.

The class makes models to study this trip. Two felt flowers stand for real flowers. Six loose yellow felt dots on Flower A stand for pollen. Flower B starts with no dots. The class tests a fuzzy cloth bee and a smooth card bee. For each test, a student gently rubs the model bee against Flower A, moves it to Flower B, and gently rubs it there.

The class uses the same flowers, starting dots, and movements for both model bees. For another test, students leave the flowers apart with no model bee. They count the dots that reach Flower B. The graph shows their results.
