Grade levels: K–3

Key Concepts: Each plant part plays a role in the entire plant's growth and development. Under the right conditions, a new plant will grow from a seed.  Roots absorb water and nutrients and green leaves are associated with making food from sunlight. (Adapted from California State Academic Standards, grades K–3.)

Estimated time: Soak seeds overnight. 20 minutes to make mini greenhouses. 10 days of care and observation.
