Seed Types
Students dissect seeds. In this seed dissection lesson, students discover the anatomy of seeds. After dissecting seeds, students hypothesize and design the perfect seed to survive in a dry forest.
Curated OER
Pollinators and Wildflowers
Students explore how plants depend on pollinators to reproduce. In this pollination lesson students dissect a local flower and collect and identify pollinating insects.
Curated OER
Plant Pollination
Students investigate methods of pollination for various flowers. In this plant biology lesson plan, students learn the parts of a flower and form a hypothesis about the method of pollination for the flower. They determine the validity of...
