Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...

What's in soil? Young scientists study the pH levels of soil from their school yard. They observe the land and area the soil came from to decide if location has anything to do with acidity level.

Groups of three scientists from the rocky planet Zog investigate the composition of soil so that they can take the information back to their home, create soil there, and begin to grow food.

Young scientists conduct a series of experiments to determine what type of soils produce the best results in roof-top gardens.

Organic or mineral? How does the matter matter? Second graders use their knowledge of the rock cycle to label the different components in garden soil.

Seventy thousand different types of soil exist in the United States alone. Young scientists learn about the importance of soil to the food supply. They test soil for a variety of factors and determine the best place to set up a community...

It takes a strong foundation to build a house and a stronger one for a bridge. This resource presents the effects of geology and soil on bridge foundations. Working in groups, the class investigates the interaction of shallow and deep...

Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...

Explore the consistency of the earth's layers and soil through modeling. By conducting an engaging experiment, learners develop a model for the earth's layers and a soil profile using edible materials. Each material is chosen based on...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...
