Energy Flow in Ecosystems

Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...

Introduce your earth science enthusiasts to the earth's energy budget. Teach them using an informative set of slides that include illuminating lecturer's notes, relevant vocabulary, embedded animations, colorful satellite maps, and a...

The bulk of this lesson plan involves the construction of both an aquatic and a terrestrial ecosystem in which to observe trophic relationships. Detailed directions are provided, as well as discussion questions, and assessment...

Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...

Energy has many forms ... but very few sources! How do we present this to young scientists? Explore the Definitions of Energy, PS3A, in a video about the Next Generation Science Standards. The narrator keeps it simple by relating...

Apply the concepts of conservation of energy to a skater to introduce a fun way the concepts apply to real life. Scholars build tracks, ramps, and jumps then analyze the various types of energy and friction. For an added challenge,...

Super detailed, this lesson will educate physical science learners about the flow of electrons. Begin by reviewing potential and kinetic energy with a moving pendulum, and then get them online to observe interactive websites about...

With the forest as an example, Sam and Zoe talk about the components biotic and abiotic of an ecosystem. They also discuss the role of producers, consumers, and decomposers. This concise clip covers all of the basics. As an introduction...

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...
