What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson plan in a short unit on climate change and the ocean helps environmental scientists answer these questions. After...

A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about...

Plants. We can't live without them! Bill Nye discusses how every living thing relies on plants using a concept called the food web. In a very visual demonstration, he ties a cord from one picture to another on a three-dimensional...

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...

Tne New York Regents High School Examinations are comprehensive and include various styles of questions, includingmultiple choice and the analysis of graphs. This particular version, the 2008 Living Environment exam surveys a variety of...

Middle and high schoolers examine the basics of a mountain lion's diet by examining food chains and food webs. Learners are each assigned one of the lion's prey species and they must construct a food chain for this animal. They see how a...

This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...

Students explain the role of different organisms in the food web. In this ecology lesson, students participate in a game to simulate mineral cycling through the web. They discuss the importance of recycling minerals and resources.

Middle schoolers explore a wide diversity of algal species; study the basic characteristics of algae and the distinguishing features of each of the 3 major divisions of algae; identify a variety aquatic plants; and make pressing a local...

Explore the food chains that support Arctic ecosystems. A class discussion on interdependence and the different roles plants and animals play in ecosystems provides learners with the knowledge to complete a worksheet asking them to...

It is always fun to weave a web when studying the relationships in ecosystems! Thirty organism name cards are provided. Divide the class into groups of eight, then give each participant a card and the group a few long strands of yarn....

Elementary ecologists examine trophic relationships using a coral reef food pyramid as an example. They play a game applying math skills that ultimately demonstrate the important role of the ever-scary top predator, the shark. This is a...

Sixth graders study the food web in a bay. In this food web lesson, 6th graders investigate the SAV- submerged aquatic vegetation of a bay including their predators, and how the organisms eat, have proper living space and water. They...

Junior ecologists relate how food chains and food webs route matter and energy through an ecosystem. They trace feeding levels of a food chain or food web through a pyramid of energy. As a reinforcement activity, learners construct three...

Here is a practical activity for reinforcing understanding of energy flow in ecosystems. Learners identify whether each organism in a list is a producer or decomposer. They tell if each is an herbivore, carnivore, omnivore, or...

This smart slide show outlines energy flow in ecosystems. It addresses the sun as the primary source of all energy, flows into explanations of photosynthesis and respiration, and explores trophic feeding levels and productivity....

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...

Focus on building strong technology skills while teaching basic scientific concepts. Fourth graders work with the school media specialist to research, collect digital images, and create a multimedia presentation on food webs. They...

Chart ecological community interactions and answer questions about niche, defenses, trophic structure, and succession. This community ecology instructional activity provides a general overview of the interactions that occur among...

Students discuss ecosystems, eliciting their current knowledge of an ecosystem. Students receive an Ecosystems document and look at the picture. Students brainstorm connection between the cover picture and ecosystems. The indicated...

A set of guided notes walks your biology or environmental studies learners through the dynamics of ecosystems. They write short answers to questions about the energy budget, food webs, trophic levels, and biogeochemical cycles. One way...

Students identify the three stages of soil decomposition. In this life science lesson, students make their own compost pile and observe its dynamics from week to week. They collect temperature data and observations.
