Students classify household items into either plastic or rubber. In this chemistry lesson, students justify their classification system. They explain the difference between observation and inference.

Students observe and classify objects that float or sink.

Pupils study directional skills and participate in a scavenger hunt to find flowers. They compare, group and classify the flowers by their similarities and differences.

Young scholars research different dog breeds. In this classifying lesson, students gather information about dogs and classify them into different groups. Young scholars will classify the dogs into small, medium and large breed groups....

Learners record and analyze what types of food monarch caterpillars will eat.

Young scholars organize different species of plans and animals according to various characteristics. Students then determine what characteristics enable them to survive in their habitat. Game ideas and activities are included.

Students investigate the presence of exotic and natural species in the ecosystem. They define the differences between exotic and native while looking at one specific ecosystem in Maryland. They write how the exotic species are considered...

Students work as a class-size unit as well as in small groups to become proficient in observing tree characteristics to facilitate species identification. They identify most common tree species by observing leaf, flower, fruit and bark...

Students examine the effect of foreign species on various habitats. In groups, they identify the population dynamics of the zebra mussel. They calculate averages and graph data from Seneca Lake in New York. They develop hypothesis...

Students spend the duration of this lesson examining the text of the Endangered Species Act. Individually, they complete a profile to determine where they stand on the bill and read excerpts from it. Some role-play the various members...

In this biology worksheet, students look for the answers to how to classify animals. They specifically focus upon the vertebrates while differentiating the characteristics from other organisms.

Fourth graders sort trail mix by type and use that information to create different types of graphs for comparing.

Students model natural selection by using various utensils to "capture food" using a simulated species called "Woolybooger's."

Students review factors that threaten survival of different species. this lesson is part of a multi-segmented unit on animal survival.

Students explore the diversity of life forms and the role that interdependency plays in our world through a mult-segmented unit. This segment introduces the unit.

Fourth graders study the characteristics of five coastal communities. They use logic cards and matching activities to identify the proper community for plant and animal species.

Students simulate the changes in a natural population of birds or other species. They establish baseline data of population fluctuation for a closed population with a stable food supply. They graph the data to complete their mutations.

Tenth graders conduct a critical analysis of current evolutionary concepts. They describe how scientists continue to investigate theories. Students examine examples with experimental data that suggest alternative methods of species...

Students examine the influence of biodiversity on human culture through the use of birds. They brainstorm words that come to mind when they think of human cultures. They describe ways that human culture and biodiversity are linked.

Students collect samples of insects and identify them. They evaluate water conditions that causes species to be found in streams and listen to sounds of water through music. Next, they respond to the music and discuss their reactions.

Students examine how animals use camouflage for survival.  In this investigative lesson students define vocabulary words and see how it is the environment that controls which adaptations will help in survival. 

Students complete an activity that allows them to better understand that birds traits are closely related to what they eat, where they live, etc.  In this bird trait instructional activity students complete an activity, create a...

Students study the lives of dinosaurs. In this dinosaur lesson, students create dinosaur dioramas that depict how and where the creatures lived. Students also discuss extinction with their teacher.

Fifth graders define words. They create a dichotomous key. After carefully examining pill bugs, 5th graders record observations. They compare and contrast habitats of pillbugs.
