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...

How is a movie theater like a desert biome? Compare systems to ecosystems with a set of activities that focuses on accessing multiple intelligences and building upon knowledge. As learners discuss the ways elements of an ecosystem depend...

Explore the Earth's different ecosystems through four lessons, an assessment, and extension activities. Lessons include informative text and step-by-step instructions to apply knowledge in interactive, and thought provoking ways; such as...

How does one organism get its energy? What is the main source of energy in an ecosystem? How does the flow of energy affect different types of ecosystems? Answer these questions with a fill-in-the-blank worksheet. 

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

Produce, consume, decompose...repeat! Examine how matter and energy cycles in ecosystems by watching a video discussing NGSS standard LS2B. The narrator explains the requirements of the standard at each grade level, plus gives tips to...

Vultures may be difficult to imagine as super-heroes. They eat rotten meat, puke acid, and certainly aren't very attractive. However, recent research has shown how essential they are to the ecosystem. A short animated video reveals how...

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...

How do ecosystems react to change over time? Show your class how natural and man-made factors affect the organisms in an area using the guidelines in a video about standard LS2C. Topics include biotic and abiotic factors, biodiversity,...
