Here is an ingeniously clever lesson on seed germination that's sure to be a hit with your kids. In it, learners create "egg people," out of eggs, egg cartons, potting soil, grass seeds, and markers. There is also a potato version and a...

How many rainforests are there, where are they, and do global factors effect their locations? These are great questions that have great answers. Children in grades four through eight use several different maps to determine why...

Students explore erosion when there are multiple types of sediments. They view a soil separation demonstration jar before and after agitation to determine how and why the layers settled. In addition, they conduct experiments with a river...

Second graders examine the six nutrients humans need to maintain good heath. In this ecosystem lesson, 2nd graders learn about how plants grow and compare how humans need nutrients from plants to how plants need nutrients from the soil....

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

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 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.

High schoolers collect and examine different soil samples. They test for specific types of soil elements and the pH level. They answer questions about optimum growing conditions as well.

Students explore the differences between specific soil characteristics. They participate in an experiment in which they discover soil texture. They write their observations in a journal.

Young scholars create a soil center on their school grounds. They begin to write in their science journals. They participate in an experiment that helps the community begin their own gardens.

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

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

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.

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 examine how soil holds together and what the effect of particle size and water content is on soil.  In this engineering lesson students complete a lab, record their observations and discuss what they learned. 

Students use wireless laptop computers to collect, store, communicate, and organize data from the 1999 Jasper Fire area. They collect data in the field and compare it to student-collected data from prior years to develop conclusions...

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.

Pupils hypothesize the role of rocks, soil, and water by observing a terrarium and create a model to explore the water cycle. This is part of a five station set up.

Students determine how pollutants can travel though sediment and explore methods of pollutant removal. They conduct an experiment on porosity and permeability of soils and simulate an EPA "pump and treat" method for removing subsurface...

In this adobe activity, students read about adobe soil and how it was used for building because of its insulating properties. Students complete 3 short answer questions.

Students compare the properties of rocks and relate these properties to their use. They perform a virtual experiment to describe and group rocks on the basis of their characteristics.
