In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this activity (located in the middle of the page), learners start a garden by planting their socks!

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

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 math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

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

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

This activity shows you how to make a mold terrarium using a jar and leftover food.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit
