Students work together to perform experiments on different types of soil. They record the soil's pH level, color and texture. They develop hypothesis' on what they believe they will discover before beginning the experiment.

Students examine the interrelationship between trees, soil and people focusing on urban areas. They collect and analyze data about trees in their research area.

Students determine the soil composition of soil layers in their area. They collect soil samples, calculate the percentage soil water content, analyze data, and evaluate each site for future tree growth.

Students examine soil samples for the presence of organic matter. They determine which soil sample from their area contains the highest amount of organic matter.

Pupils examine how an estuary's plants and soil filter water before it flows into the ocean. They complete a lab report drawing and writing about what they observe after completing a water filter activity.

Students study the effects of water erosion on soil by gathering and analyzing data during an experiment. They decide on appropriate units of measurement to apply in problem solving.

Students study the four layers of soil while identifying the substances that each level is composed up. They investigate the properties of soil such as color, texture, water retention and the ability to maintain life by growing a plant.

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Fifth graders compare and contrast the rate of soil erosion along water and along a vegetation area. They observe the differences and record their information and write a hypothesis of what they think happen if the erosion continues.

Pupils observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.

First graders compare and contrast different seeds before planting them. They assess the basic needs to plants and conduct experiments of deprivation of those needs. They write stories and draw pictures of plants which are bound into a...

Eighth graders examine the components of a watershed. They view overheads, discuss the hydrologic cycle, and observe a demonstration of a soil erosion box.

Students investigate rocks and minerals and take a field trip to sample soils. They analyze rocks and soil, research the geological terrenes of the topology of San Francisco, and produce a lab research report.

Students complete an activity by looking and gathering data on plants and soils.

Eighth graders explore how to take soil samples and use GPS to determine the location of the site they have chosen to take the samples.

Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.

Sixth graders collect soil samples and record the location of the samples by using GPS.

Sixth graders take soil samples and analyze the samples and ecosystems found within them.

Ninth graders take soil samples and perform tests on these samples.

Students observe and classify the permeability of a variety of materials.

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead...

In this comprehensive interactive tutorial you will investigate the area of forensic science and how the various types of evidence differ. Learn what types of crimes involve glass and soil and what ways these types of evidence are...

Material to launch exploration of Earth's soil and its important role. View a one-hour video, accompanied by details on soil horizons and soil formation, and ideas for bringing this topic into the classroom.

Understand how the components of soil effect plant growth.
