Don't harbor any negative feelings toward negative numbers. Scholars learn about different classifications of rational numbers, including negative integers. They also develop definitions of the opposite and the absolute value of a...

Students consider the interdependency of life in a temperate forest by studying selected organisms from an Asian temperate forest and creating a food web.

Students participate in an interactive game to review how living things are classified.

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.

Students describe food cahins and the role of organisms. Using a set of organism cards, they color code the organisms on their cards by their role in the food chain. Once a complete chain is identified, they glue it on a sheet of paper.

In this mammals activity, students research the internet to find information and answer short answer questions about mammals of fields, meadows, and hedgerows. Students complete 12 questions.

This PowerPoint includes a game with ocean graphics in which two teams answer increasingly difficult questions about animals. Topics covered include plant and animal cells, animal adaptation, and similarities and differences between...

Learners generate questions about grizzly bears and use the Internet to research the answers. As a culminating activity, students create a life-size mural of a grizzly that is annotated with the information they've learned.

Students investigate the components food chains and food webs in various ecosystems. They describe how living things depend on one another for food energy (food chain) and how more than one food chain exists in an ecosystem

Fourth graders study food chains, producers, consumers, and decomposers. They play a food chain game and create food chain mobiles or posters. They take a nature hike around the school and observe various parts of a food chain.

Seventh graders, using national parks as models, illustrate the energy flow in ecosystems. Working in groups, they use murals, flow charts, or other visual displays to record their findings. Students represent the food chains and webs...

Students plan, practice, and act in a 2-3 minute videotaped production about a specific topic. Students from a local high school give presentations pertaining to seasons, earth rotation, and moon phases. Students analyze the...

Students design an appropriate and usable storyboard and then create a claymation video. They take digital photographs frame by frame, then assemble the stop-motion movie using video software.

Fifth graders research an animal from the ocean, using the internet and encyclopedias, with at least 5 out of 5 topics covered. They also construct a 3-dimensional model of their animal and give an oral presentation about their animal...

For this science worksheet, students identify a specific dinosaur to research. Then they develop an overview of their dinosaur family and the foods each dinosaur in their family eat. Students also identify how the dinosaurs defend...

In this environmental issues learning exercise, students respond to 14 different types of questions divided into 3 sections. First, they define global warming and give an example of what they can do to slow it. Then, students define 4...

In this mammals' teeth and diet worksheet, students read for information, identify kinds of teeth, and sort animals into categories. In this fill in the blank and T-Chart worksheet, students write multiple answers for two questions.

In this ecoregions of Texas worksheet, students complete a summary of a particular ecoregion in Texas. They find the producers and consumers of the region, they draw a food chain, the draw a food web, and they complete an energy pyramid...

In this animal sorting worksheet, 5th graders first match animal pictures with their names and a fun fact. Students must then fill in 15 blanks based on information given on the matching cards.

Fourth graders classify animals. In this animal kingdom lesson, 4th graders research animal habitats and behaviors. Students connect to a zoologist via SKYPE and learn about animal classification. Students blog about preserving animal...

Sixth graders observe the pond ecosystem. In this ecosystem lesson, 6th graders observe the organisms at the pond and create a poster that illustrates the pond.

Students explore the concept of insects and their habitats.  In this insect habitat lesson, students create travel brochures for particular insects.  Students must include habitat, producers, and consumers with in the vacation...

Students investigate the food chain by researching the Internet.  In this ecosystem lesson plan, students view the video "Competitor and Predator" and read a book from the series "The Magic School Bus."  Students utilize a...

Students investigate a rainforest food chain. In this ecology lesson plan, students are shown pictures of plants and list what animals might eat the plants. Students continue to think of what other animals might eat those animals....
