At one time or another, students are given the opportunity to explore the bean plant. Lessons usually start with the bean seed to develop an understanding of a bean's beginning. Activities might include identifying the seed parts, or demonstrations on photosynthesis and transpiration. Subsequently, students will germinate and then plant a bean seed to discover its life cycle. Once the bean sprouts, students will be required to record and label the parts of the bean plant. This objective is achieved in stages concurrent with the life cycle or in preparation before the plant actually flowers.

Step 1

Label the bean plant's root hairs, which are fine filaments that branch off the ends of the roots. Under the soil, these hairs absorb the water and nutrients.
Step 2

Identify the bean seed, which has two sides called cotyledons. Roots are found at the bottom of the two parts of the seed. Once the bean seed germinates, the roots will shoot outward and anchor the bean plant in the ground.
Step 3

Put a label on the main stem, which sprouts from the embryo as the roots grow. Similar to a tree trunk, its function is to hold the bean plant upright, support the leaves and store nutrients.
Step 4

Mark the secondary stems, which will grow out from the main stem. From these secondary stems, leaves will grow.
Step 5

Label the flowers at the top of the bean plant, which develop during the bean's life cycle. These flowers will eventually produce bean pods.

Tips & Warnings

Compare and contrast a dry and wet bean seed before beginning the germination process.
Augment the lesson with an introduction of the parts of the flower.
