In this activity, young learners will make their own flower seed nursery in an egg carton.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this outdoor activity, learners discover that plants aren't just shoots (stem, branches, leaves, and flowers) growing above ground, but contain plenty of roots growing underground—more than half th

In this activity, learners explore patterns and sequences as they observe fictional plant growth.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.

In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

Learners use a transparent plastic glove as a container to grow seeds. A different kind of seed can be planted in each finger.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
