Energy Flow in Ecosystems
Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

The Water Cycle
Explore the water cycle with a hands-on earth science activity that prompts pupils to measure the amount of water normally transpired by plants. After they describe the flow of the water cycle and provide examples of how human activities...

Exploring the Water Cycle
Students investigate the water cycle. In this water cycle instructional activity, students create an ecosystem within a 2-liter bottle. Students record scientific observations as they observe the water cycle within their ecosystem.
Curated OER
Aquatic Ecosystems
Students study the diversity of marine life and their habitats. In this aquatic ecosystems instructional activity students complete a lab activity and experiment.

How Does Your Ecosystem Grow?
Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Energy Flow in a Wetland Ecosystem
How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson....

Water's Edge Café
Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

Ecosystem Interactions in Refuges
Seventh graders, using national parks as models, illustrate the energy flow in ecosystems. Working in groups, they use murals, flow charts, or other visual displays to record their findings. Students represent the food chains and webs...

Observing a Stream Ecosystem
Students use their five senses to explore a river ecosystem. They experience how their senses provide them with additional information about the environment through the use of teacher made stream boxes.

Water Quality Assessment
Students evaluate water quality of different sources. In this water assessment lesson students chemical testing, identify biological factors in the stream, and write a paper on their position of the stream's quality.
Curated OER
The Water Cycle and Global Warming
Students study the flow of water in the environment. In this water cycle lesson students evaluate the consequences of changes in the water cycle using data.
