1.LS.1: Living things have basic needs, which are met by obtaining materials…

Plants and Seeds: What Does a Seed Need? Grade 1 · partly supports this outcome

What's hiding inside a bean, and what does it need to wake up and grow? Young scientists open soaked seeds, sprout beans in bags and watch seedlings bend to find the light.

• What does a seed need to grow? Day 1: 40 min. Then 5–10 min check-ins for 7 to 10 days, and a 25 min wrap-up

  Each team puts beans in three zip bags: wet in the light, wet in a dark cupboard, and dry. Over 7 to 10 days children keep a picture journal and find out that a seed needs water to start growing, and that light matters once the little plant is up.

• Why do plants grow toward the window? Day 1: 40 min. Then 5 min check-ins for 1 to 2 weeks, and a 20 min wrap-up

  Children turn young bean plants away from a window and watch them bend back toward the light, and they set a seedling inside a shoebox maze to see if it can find its way out. They explain that plants need light and grow toward it.
