  2. For each student: Student notebook 1 bee stick Plants with open flowers STC Plant Growth and Development Lesson 11: Pollinating Flowers Materials list For every two students: • 1 hand lens

  3. STC Plant Growth and Development Lesson 11: Pollinating Flowers Pick up your plants, bee sticks, and hand lens from the distribution station.

  4. STC Plant Growth and Development Lesson 11: Pollinating Flowers Use the bee to transfer pollen from the blossom on one plant to the blossom on another plant. Pollinate every blossom that is open by rotating the bee gently.

  5. STC Plant Growth and Development Lesson 11: Pollinating Flowers Remember to cross-pollinate! Brassica flowers must be cross-pollinated. That means the pollen from one plant can not pollinate any of the flowers on that same plant. Pollen must be carried from the flower of one plant to the flower of another plant.

  6. STC Plant Growth and Development Lesson 11: Pollinating Flowers Use the hand lens to look for: • pollen on different parts of the plant • pollen trapped in the bee’s hairs

  7. STC Plant Growth and Development Lesson 11: Pollinating Flowers Clean up and put all supplies where they belong.

  9. STC Plant Growth and Development Lesson 11: Pollinating Flowers What does the bee get from the flower? Figure 11-1 • In real life, what attracts the bee to the flower? • How does the bee reach the sweet nectar in the bottom of the flower? • What else do you notice about the bee?

  10. STC Plant Growth and Development Lesson 11: Pollinating Flowers • Look for the female parts of the flower—the pistil with the sticky stigma. • Look for the male parts of the flower—the anthers on stalks called filaments. The anthers hold the pollen. • How do you think the male part (pollen) of one plant can get to the female part (stigma) of another plant? What does the flower get from the bee? Figure 11-1
