Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

Tenth graders examine how energy is lost through different trophic levels.  In this trophism lesson students construct a food web and view a video. 

Students explain the main concepts of food webs and food chains. They describe the role of animals, plants, and other organisms in cycling energy and matter through a food web by creating mobiles. Lesson contains adaptations for all levels.

Students study life science. In this food webs and food chains comparison activity, students examine the wetlands to discover the relationships that exist between the animals that live there. They participate in group activities and...

Students discuss the concept of a food chain in the California ecosystem. in this food chain lesson, students look at different cards and sort them into herbivores, carnivores, decomposers, and omnivores. Then they use these cards to...

Learners investigate the effects of the food chain on all animals by creating a food web.  In this seafood lesson, students discuss energy flow and research a specific marine organism of their choice.  Learners create a food...

Fourth graders examine roles of animals in food chain, explore roles of humans, plants, and animals in ecosystem, create their own food webs, and role play producers, consumers, and decomposers.

That's Amazing! is the theme of an English language development unit created by Houghton Mifflin. Following a speak, look, move, and listen routine, scholars delve into topics; seasons, weather, animals, landforms, telling...

Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the activity uses a variety of plant and animal cards to have scholars build an arctic...

Students explore the differnences between food producers in food webs and food consumers in food chains. Behavioral choices of primary and secondary consumers such as herbivores, vegetarians, carnivors, and omnivors are analyzed.

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....

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 demonstrate understanding of food chain by assuming roles of animals, playing tag, and simulating feeding relationships.

Students explore the many different food chains. They participate in a game in which the class is divided into the different parts of the food chain.

Once your physical science stars have a grasp of the different forms of energy, use this resource to get them putting the energy to work. Small groups choose from seven different project options and work together to build an energy...

Young learners take a look at what they eat in one day and compare it to how much physical activity they do on that same day. Point out that this is only a one-day glimpse at balancing the energy going in and what energy being used. They...

Students investigate how food provides energy for the human body. In this physical health lesson, students access online resources to identify how certain foods can affect their health. Students discuss how many servings of each food...

Students explore human energy components. In this personal health lesson, students determine how food, sleep, and exercise impact human energy levels as they play BAM! Body and Mind  interactive games. Students create motivational...

How many Calories one needs on a daily basis is dependent on a number of factors including gender, height, and activity level. In the third of seven lessons about energy and food, young nutritionists calculate the number of Calories...

Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...

Students measure the amount of calories in food. In this food energy instructional activity, students discuss what a calorie is, how our bodies use a calorie, and how many we need. Then, students use a calorimeter to calculate the amount...

Students explore the concepts of energy resources and energy transfers. In this chemistry lesson plan, students examine renewable and non-renewable energy sources as they view classroom demonstrations and discuss the concepts as well as...

Students distinguish between items with and without energy. In this energy lesson, students understand that natural resources power electrical apparatus and that energy needs to be saved.

In this food chains worksheet, students complete a crossword puzzle by placing 16 terms into the puzzle that match the clues given. Students review food webs, biomass pyramids, and the water cycle.
