- Nectar — a sweet liquid made by flowers that attracts animals (pollinators) (Lesson 1A/1B)
- Petal — the bright colorful parts of a flower (Lesson 1A)
- Pollen — colorful dust made by the flower, that allows the seeds to form (Lesson 1A)
- Pollination — the process including wind, water, and animal movement that allows plants to reproduce and make more plants (Lesson 1A/1B)
