Populations and Ecosystems
Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.
Curated OER
Tanker Spills
Students predict the flow of an oil spill and depict it on a map. They explain the predicted route of the oil spill using knowledge of ocean currents in a short presentation to their peers.
Curated OER
Toward a Sustainable Agriculture
Students examine how to use ecological analysis to animal production systems. In this sustainable agriculture lesson students examine where the nutrients flow in a system and complete several activities.
Curated OER
Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Atmospheric Cells
Students recognize that the sun is the source of energy driving atmosphere cells. They relate the motion of the atmospheric cells to mantle convection cells. Students recognize that the function of atmospheric cells is to move heat from...
Curated OER
Marine Food Webs
Students examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.
Curated OER
Introduction to Elementary Circuits
Learners explore how a circuit works and create a circuit to use energy from a battery to light a bulb. In this introduction to circuits lesson, the students study the parts of a circuit and have a class discussion of what would happen...
Curated OER
Food Webs
Students research rainforest animals and use that information to make a flow chart to show the order in which energy is transferred through several organisms. They label the producers, consumers, and decomposers in their chart.
Curated OER
Groundwater Detectives
Students measure the pH of soil samples from a hypothetical site to locate a contaminant spill and will predict the direction of groundwater flow using mathematical modeling. They use the engineering design process to develop...
Curated OER
Build a Simple Ammeter
Students build and work with a simple ammeter to test theories on why solar cells connected in parallel produce more current that in series. Students use the ammeter to indicate the presence, direction, and strength of an electric...
Curated OER
Homeostasis and the Plasma Membrane
For this homeostasis and the plasma membrane worksheet, students complete a flow chart and 5 questions related to homeostasis and the plasma membrane. They complete a flow chart that illustrates the plasma membrane and cellular...
Curated OER
Transportation Systems
Students examine transportation systems and explore problems created by modern transportation. In this transportation systems lesson, students discuss various forms of transportation as it relates to depletion of our natural oil...
Curated OER
Stepping Inside the Flowchart: How Does a Bill Become a Law?
Learners explore the steps a bill must pass through to become a law and create a flow chart that maps the complexities of the process. They research the committees that are involved in a bill that relates to energy policy and the...
Curated OER
Diffusion
Students are asked how does odors move around without energy? They relate concentration gradients, diffusion, and equilbrium and predict water movement into and out of cells. Students are shown a demonstration where the teacher sprays...
Curated OER
One Tough Worm
Students explain the process of chemosynthesis and its relevance to biological communities. In this investigative lesson students discuss chemosynthetic communities, then in groups they are assigned a species and are to calculate the gas...
