Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

Learners work together to build their own fish ecosystems. As a class, they share their prior knowledge about catfish and use a diagram to label its body parts. They record their observations of the ecosystem and determine what they...

Learners explore the freshwater ecosystem of Africa's Lake Victoria by creating a freshwater aquarium. They investigate factors affecting the aquarium's ecosystem and conduct lab activities.

Students investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.

Learners investigate the environment by participating in a class trip. In this pond ecosystem lesson, students define a list of vocabulary terms associated with ponds such as invertebrate and metamorphosis. Learners attend a field trip...

Learners discuss the types of technology that are used to control the population of sea lamprey in the Great Lakes. They explain the parasite/host relationship and understand the devastating impact invasive species have on ecosystems....

A food web consists of complex food chains and the more complex the web, the better likelihood of survival. Learners compare and contrast food webs and food chains and discuss concepts like the predator-prey and consumer-producer...

Students discuss the importance of plankton in the ocean ecosystem. For this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.

Learners are taught how to format and enter data into an Excel spreadsheet. They make a graph, and interpret graphed data. Students discuss the possible impacts of zebra mussels on the Hudson river. They graph zebra mussel data.

Students investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

Fifth graders investigate how humans pollute the water supply with a number of different contaminates. While working in small groups they examine screening, sedimentation, filtration, and chemical treatments as methods of water treatment.
