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...

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...

Class members analyze the water content in soil samples by drying out the samples and taking measurements every minute until all the moisture is gone. Scholars compare the initial weight to the dried weight to calculate the percentage of...

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...

Bored with your current biome bag of tricks? This bundle is a bountiful bag of biome fun! Travel the globe with seventh graders and explore the biotic and abiotic factors that define our world's biomes. Then, introduce a little chaos to...

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the variety 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.

Erosion is the leading cause of the loss of topsoil and sediment deposits in ditches, streams, rivers, lakes, and oceans. The ninth lesson in a 10-part series includes two different activities related to soil erosion. First, scholars...

Hydrangea flowers change color based on the pH of the soil. Pupils analyze soil, an abiotic component of ecosystems. They research the pH of their local soil, record their findings, and then compare them to the pH found on campus.

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 the role that...

Students, in groups, conduct an experiment to compare how water moves through different soils. They discuss how different soils could have an impact on different plants.

Eighth graders identify the composition of a soil sample. In this archaeology lesson, 8th graders describe the different soil layers formed in their activity. They explain how this pattern help archaeologists evaluate soil types.

Students examine soil. In this soil composition lesson students participate in soil sedimentation and filtration activities. The students discuss what non-living and living things are in soil and why it is so important.

Fifth graders examine how sand and rock fragments in soil are products of erosion or the weathering of rocks. They listen to the book "Sand" by Ellen J. Prager and answer discussion questions. Next, they analyze sand samples and sort...

In this earth science worksheet, students complete a chart by describing different types of rocks and soils. They search for the specified rocks in their world and describe them using the words in a word bank at the bottom of the page.

First graders awareness is raised that not all dirt is the same. They compare and observe particle sizes in three different kinds of soils. They keep a record book of what the discover and talk about how some soils are alike and some...

Students identify the soil types and textures, and locate the waterways in or near the towns of Lyons and Decatur, Nebraska. They analyze soil profile maps, and answer conclusion questions.
