One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Students conduct scientific investigation in which they observe glacial effects on landscape, develop and explain their own theories of how glaciers change land, and demonstrate understanding and explain basic motion and force principles.

High schoolers distinguish between walking, jogging and running trackways in humans. They analyze the phylogenetic progression of the leg position as described by pace width and angulation, comparing amphibians, reptiles and mammals....

Students define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

Students identify fossils. They identify evidence of change over time when given pictures of fossils to determine the proper sequencing. In addition, they determine evolutionary relationships by comparing embryonic structures.

Students discuss the difference between designed and natural elements. After reading an article, they discover information about current controversies in evolutionary science. In groups, they research and write dialogues between two...

Students transfer examples (names) of primates from their location in an outline hierarchy of primate groups into a set of nested boxes reflecting that same hierarchy. A cladogram can then be drawn illustrating how these groups are...

Learners count the number of varves (annual layers of sediment) in shale billets, taken from the Green River Formation in Wyoming. The count is then extended to reflect the entire 260 meters of sediments where the billets originated.

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

What makes a poem difficult? Explore that topic and more with your class as you work through the lesson detailed here. Using materials from Poetry Out Loud, a national recitation contest, individuals or small groups examine poems and...

Students in a teacher education program are introduced to the constructivist theory. In grade level teams, they take their subject matter focus and create lesson plans related to the constructivist theory. They are graded with a rubric...

Pupils use discussion questions, handout information and research topics to explore several issues related to natural selection and evolution. They examine Darwin's research on the finch and antibiotic resistance.

An interesting instructional activity on hypothesizing about the diameter of a drop of blood that is splattered. To test their theories, learners work in groups to make blood droplets splatter from different heights. They use graphed...

Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.

Learners discuss plate tectonics and the layers of the earth's interior. They use eggs as models of the earth and answer questions regarding which part of the egg would represent which part of the earth.

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Sixth graders will simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be...

Students evaluate data related to population growth, along with problems and soultions: disease cvontrol. They are able to explain how changes in habitat may affect organisms. Students evaluate evolutionary theories and processes.

Learners analyze an animal's life cycle and behaviors, and examine what animals need to stay alive and reproduce. They develop theories and hypotheses about the reasons for migrations, using the Journey North online project.

Students brainstorm a list of all of the ways they use energy in a day. In groups, they research the energy situation today and discuss what is being done to solve the problem. They also examine the issues related to this in politics...

Students explore why people get cancer. They explore human cells by taking a close examine their own. take a small sample of the epithelial cells that line the inside of their mouth. They glimpse how scientists investigate inside cells.

Students read and understand the importance of energy sources.  In this Renewable and nonrenewable lesson, students read an article to become familiar with the uses of energy.  Students read an article and answer questions...
