Chemistry And The Nitrogen Cycle
Students investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the instructional activity. Students define the nutrient that is often limiting to plant growth...
Curated OER
Water and Ice
Students explore the physical properties of water. For this water lesson, students explore water as it changes states. They observe, measure and use communication skills to describe change.
Curated OER
Earth Systems
Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.
Curated OER
Structure of the Earth System
Eighth graders describe the steps in the water cycle. They discuss factors that affect runoff and explain the differences between stalactites and stalagmites. They discover the importance of ground water.
Curated OER
Up, Up, and Away
Learners create a model to explore the water cycle. Students also perform different experiments to witness water changing from a liquid to a gas. Learners are asked to if they can find ways for water to go away without pouring the...
Curated OER
Linking Lines to Landscape
Students evaluate art to enhance their core knowledge of fiction, American folk heroes, and the water cycle. In this art lesson, students complete a unit of activities to use art to study various topics of literature, history, and...
Curated OER
Water Pollution and Food Chains
Students investigate the two key concepts covered in this lesson: first, how pollution can affect plants, and, second, how polluted plants affect the rest of the food cycle. In sum, this lesson teaches students about "Bioaccumulation".
Curated OER
Changing State
Students identify the changing states of water, water vapor and ice in the water cycle They investigate how each of these stages can be reversible. Students complete a worksheet describing the water cycle.
Curated OER
The Path of Water
Third graders discuss the sources of water, the path it takes to get to homes and businesses, and the ways we use water. Students begin by expanding their awareness of the hydrosphere as they research the water cycle, the sources of our...
Curated OER
The Path of Water
This project is designed so students can learn about the sources of water, the path it takes to get to homes and businesses, and the ways we use water. Students will begin by expanding their awareness of the hydrosphere as they research...
Curated OER
Local Weather And Location
Students explain how uneven heating of Earth affects wind and water currents. They describe the limits on current technology in predicting weather and how the Water Cycle is related to local weather.
Curated OER
Measure It Up!
Students investigate the states that water may take. In this physical science lesson, students read the book, Water: Up, Down, and All Around and recall the states of water from the book. Students examine how water takes the shape of its...
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...
Curated OER
Structure of the Earth
Seventh graders study the cause of climate change, and how clouds form and affect weather. They define condensation and precipitation, the greenhouse effect and the water cycle.
Curated OER
Latent Heat and Clouds
Students explore latent heat and how it relates to clouds in the atmosphere. For this earth science lesson students investigate how clouds are formed. Students examine clouds and the water cycle.
Curated OER
Global Water Cycle & Heat Flow
Students experiment to discover how different variables affect the water cycle. They do hat flow experiments and construct a computer heat flow model.
Curated OER
Climate & Atmosphere: A Global & Local Perspective
Young scholars complete a series of activities in which they study atoms, molecules, and the presence of atmosphere. They study the water cycle and the Greenhouse Effect by investigating and completing handouts.
Nuffield Foundation
Nitrogen-Fixing Bacteria in Root Nodules of Leguminous Plants
Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.
Curated OER
Investigating the Hydrosphere
No matter the scientific discipline, your students can benefit from a study of water.

Fred the Fish -- A River Ran Wild
Students apply cause and effect relationships to water pollution in a stream. In this pollution instructional activity students recognize the importance of clean water in their daily lives. Students accompany "Fred the Fish" as he...
Curated OER
Car Wash
Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

Water Pollution
Young scholars study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and...
Curated OER
Life Is a Cycle
Students investigate about cycles through games, shared readings and a shared writing activity. They play a game of Ring Around the Rosie to be introduced to the concept of "cycle."
