Guide your students through the process of opening up a frog. The resource provides step-by-step instructions for dissecting a frog, as well as guiding questions to answer throughout the lab.

Fourth graders explore life cycles and the metamorphic process. In this life science lesson, 4th graders work in groups to study a group of creatures and metamorphosis. Students view examples of metamorphic and non-metamorphic life...

Second graders explore the geologic process of fossil formation. In this geology instructional activity, 2nd graders discuss the job of a paleontologist and make their own model of a fossil. This instructional activity includes teacher...

In this water worksheet, students read an excerpt about the effects of pollution on the life cycle of a lake. Then they describe how lakes are affected by the pollution. Students also define why pollution has become such a problem for...

Pupils consider community and legislative efforts to stop puppy mills. In this animal welfare lesson, students discuss the needs of pets and determine how puppy mills do not meet the needs of animals.  Pupils research animal cruelty...

First graders examine the life cycle of the frog, and research frogs of the Nez Perce reservation and their requirements for survival. They observe the development of frog eggs and record their observations in science journals.

Fourth graders explore the plant life cycle. They discuss the sequence of events in the life cycle of the plant and illustrate how the life cycle never ends. Students explore the importance of water, sunlight, and nutrients during the...

Third graders review the life cycle of a frog. They use the computer to research specific information about their frog and write a descriptive paragraph using the information obtained on the computer. They access websites imbedded in...

Students compare and contrast the types of coverings found on animals. They identify a wide variety of animals in a museum room. They classify animals based on their coverings as well.

Your class will love exploring animal conservation through this lesson on bats. Learners discuss the importance of bats in the ecosystem and talk about the different types and their characteristics. As a follow up, a model of a bat or a...

Students are introduced to the relationship between light and vision. In groups, they participate in experiments to discover how different wavelengths are divided in the visible spectrum. They record their answers and discuss their...

Students discover the harm and benefits of microbes. In this biology lesson, students explore water, nitrogen and carbon cycles. They investigate the factors affecting bacteria growth.

Students utilize satellite images to track the life cycle of vegetational growth over a large area. Animal migratory patterns are compared to this cycle.

Middle schoolers create a dichotomous key. In this categorizing lesson, students create a dichotomous key for different types of cereal. Middle schoolers classify the cereal into groups such as flakes and cereal with holes. Students...

Learners recognize the different types of plants and animals living in a local environment. They determine how they require different habitats to live, and relate simple life processes to plants and animals found in local environments.

Learners explain in their own words why organisms live together. In this biology lesson, students model what happens to organisms if their environment changes. They explain the importance of evolution.
