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 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.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

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

This guide outlines how to plant a garden even if you don't have a yard!

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

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.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

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.

Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

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