Study Soil
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.

What's in the Soil?
Fourth graders examine soil to find its contents, and how much water and air they can measure. In this soil composition lesson, 4th graders perform three experiments and record their results. In one experiment they examine the soil for...

Investigating Planetary Soils
Learners study soil characteristics and identify properties of soils from different parts of the solar system. In this soil lesson students divide into groups, read soil descriptions, test and record soil samples.

Soil Composition: Then and Now
Students identify the location of their school from a 1926 digitized Soil Sample map. Using remaining landforms, they determine the type of soil identified during that time, and compare it to the soil currently found near the school.

What Kind of Garden Would Grow in Our Schoolyard?
Students perform soil tests for pH, nitrogen, phosphorus, potassium, composition and water percolation rate and assess the conditions in the schoolyard.

Lab: Percent of Composition of KClO3
Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Fertilizing Chile
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...

What is the Composition of Soil?
Students examine the different components that make up soil. Using data, they identify the components of soil in their local area and discover how scientists use the soil to see how it was formed. They also describe the soil forming...

Determining the Percolation Rate of Soil
Students discover how water moves through different types of soils. In groups, they use the same sample from a previous activity and empty it into a milk carton in which they have layered with cheesecloth to determine the percolation...
Curated OER
Necessary Nitrogen
Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

What's in Wetland Soil?
Students examine the organic and inorganic components of soil. In this environmental science lesson, students identify the factors that influence soil formation. They collect soil samples, conduct tests, and analyze the results.

Field Trip Preparation
Students prepare for a field trip. They navigate through a Underground Network site. This "field trip" can be conducted in a patch of healthy grass or soil anywhere you can find it: right outside your building, in a backyard or at a...

Traditional Soil Remediation in the Garden
Young scholars use testing kits to analyze garden soil. They research the nutritional needs of various crops as well as the nutritional properties of fish. Students participate in fish harvesting for garden fertilizing.
Curated OER
The Properties of Clay
Sixth graders determine the physical properties of clay by examining ceramic works of art. They evaluate local soil samples for suitability for sculpting and compare clay taken from soil to manufactured clay.

The Water We Drink
Third graders relate that the quality of their drinking water is subject to the condition of the environment and water found in streams and creeks in their community. They track the travel of a wad of paper from a student's desk to a...

You want me to do what with this Dirt?
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.

Detecting Magnetic Materials in "Martian" Soil
Young scholars simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this...

ME402: Growth of Yeast
Students investigate the growth of yeast in a sugar solution. They verify the pressure of carbon dioxide using bromothymol blue. Students are asked to describe the difference between the contents of the test tubes used and to explain...

pH Potential
Students experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH...

Reflection and Absorption of Light
Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...

Reading the River
In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Seeds of Wetland Life
Students participate in several activities on seed exploration. In this biology lesson plan, students classify seeds according to their dispersal method. They explain the different adaptations plant have to disperse their seeds.

Looking At Acid's Effects On Metals
High schoolers perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

Rocks, Minerals, and Erosion
Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic
