How Hot is Too Hot?
Fifth graders use the scientific method to conduct experiments on the temperature effects on organisms. In this temperature effects on organisms lesson plan, 5th graders observe and record the hatching or the developing of organisms into...
Curated OER
Sounds of the Wetlands
Students identify the sounds of different bird calls. For this biology lesson, students create a sound map. They explain how this method is important in tracking wildlife.
Curated OER
Composting "The Right Mix"
Students investigate the correct mix of material types for compost. In this composting lesson plan, students explore the correct amounts of different types of materials to create a compost heap. Students then create a compost heap.
Curated OER
Causal Patterns in Ecosystems Section 3
Students design and create a worm and worm free compost tanks for observation of decay in ecosystems. They make predictions, care, and revist tanks using their journals for observation and data collection.
Curated OER
Rock Cycles, Crayon Cycles
Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...
Curated OER
A Model Aquifer
Students build a model that depicts how water is stored in an aquifer. They examine ways in which groundwater can become contaminated.
Curated OER
Biodegradability
Students study the effects of water, salt water and heat on common household materials. They separate an emulsion and show that the materials are completely recoverable and observe the effect of acetone and water on polystyrene.
Curated OER
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
Curated OER
What's The Level?
High schoolers examine the movement of the water table and saturation zones. They describe the movements of the water table and locate the saturation zones. Students identify the function of each saturation zone. They develop a model of...
Curated OER
Biotic Factors
Students identify individual organism, a species, and a population within the study community. They identify biotic factors at the site and attempt to characterize the site's species diversity.
Curated OER
How Much Has Math Changed?
Students solve problems using the opposite, reciprocal and powers. In this algebra lesson, students solve problems with inequalities and absolute values. They show understanding of the basic content of math in this lesson.
Curated OER
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.
Curated OER
School Site Ecosystem
Fourth graders are introduced to the concept of ecosystem; specifically, the interrelationships among plants and animals within an ecosystem, and their relationships to the environment in which they live and interact.
Curated OER
Weathering and Erosion Splashdown
Fourth graders investigate how plants and their roots help slow the erosion process.
Curated OER
Comets and Meteors
Learners construct a model of a comet nucleus using dry ice. They add other materials and describe the features. They complete related exercises on an Internet Web site.
Curated OER
Earth's Atmosphere and Temperature
Learners explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...
