Energy Flow - How Much Biomass do Plants Produce?

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...

Fifth graders take a close look at how energy changes from one form to another within their surroundings. They also study the ten different sources of energy and determine which are renewable and which are non-renewable. This seven-page...

Nuclear power provides about 20 percent of the energy generated in the United States. The seventh activity in the series of 12 tackles nuclear power. After sharing what they know about nuclear energy, scholars complete a...

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...

OSHA confirms that rules governing worker safety at nuclear power plants ranks higher than worker safety in offices. Scholars must consider safety, cost, alternatives, and other factors before recommending whether a town should build a...

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...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

All types of energy are presented here, with neat pictures and labels to illustrate the technology typically used. Ways of harnessing the energy most efficiently are discussed, and good examples provide starters for further research....

How do you plan to approach standard LS1C, Organization for Matter and Energy Flow in Organisms? Avoid information overload with helpful advice in a short video. Topics include energy sources, relationships between organisms, and...
