Students measure and correlate their foot lengths and body heights, then use this data to estimate height of Laetoli hominids. They use metric measurement and graphing to determine these heights.

Young scholars actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

Students consider two sets of simulated fossils (caminalcules) that are provided as cutouts. They arrange them on two time scales. One set produces a visual example of gradualism, the other shows punctuated equilibria.

Students, in groups, study cheetah, blind cave organisms, and naked mole rats to explain facets of evolution.

Students develop likely phylogenies for seven related populations of lizards living on the Canary Islands using real data. They organize charts, and record the data for geography, geology, morphology, and molecular genetics.

Learners define term interest group, identify interest groups that people in the local community belong to, and contact an interest group and evaluate the impact of that group on the political process.

Students define term federalism, identify the powers granted to state and national government, and identify powers shared by the state and national governments.

Pupils define term representative democracy, explain how the government responds to the needs of its citizens, describe the role of citizens in a representative democracy, and explain how citizens can influence public policy.

Students explain purpose of government, describe functions of government, and explain how the government impacts individuals and society.

Students explain why it is important to participate in government, and name at least three ways citizens can participate.

Students describe role that money plays in politics, and write an editorial that explains whether or not they think money gives some people too much influence in government.

Students explore the average surface temperature of planets. They use the Planet Temperature Calculator to find the average temperature. Students explore how the distance from the sun affects the Earth's average surface temperature. They...

High schoolers identify the different components that make up the federal budget. They discuss the relationship between government revenues and spending and between budget deficits and the national debt. Students predict how changes in...

Students explore the day in the life of a U.S. Congressman through a multimedia presentation. They view the activities of Representative Zach Wamp of Tennessee as he meets with constituents in his home district. In small groups, they...

Students construct segments of DNA to create a piece of jewelry.  In this genetics lesson students create a DNA sequence that they turn into something to wear. 

Seventh graders examine fossils.  In this vertebrate fossils lesson students view a demonstration.

Students view a Power Point and complete activities related to genetic evidence of human evolution. In this molecular evolution lesson, students view and discuss a provide presentation. They search for the "tell-tale telomere" and...

Learners examine the three domains of life and explain that all living things share a common ancestor.  In this paleontology lesson students are introduced to the process of illustrating evolutionary relationships. 

Young scholars use Biology Workbench to explore DNA sequence data for the GULOP gene in humans, chimpanzees, orangutans, and crab-eating macaques and the beta globin gene and its pseduogene in humans, gorillas, and chimpanzees.

Students describe, measure and compare cranial casts from contemporary apes (chimpanzees and gorillas, typically), modern humans and fossil "hominids" (erect and bipedal forms evolutionarily separated from apes).

Students view various types of illusions. Using one of the illusions, they try to determine how a scientist might explain them. They discover a t-illusion and use their own words to analyze them. In groups, they research a different...

Students examine the use of a "magic hooey stick". They discover the concept of illusions and how science can reveal them. They answer discussion questions to end the lesson.

Students examine the concept of astrology. They compare their traits with those of standard astrological descriptions. They discuss their findings.

Students, in teams, attempt to solve a simulated crime scene.
