Students examine how species evolve over time and how this can change a population.  In this environment lesson students complete a worksheet on finches.

Pupils explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Students explore a model that illustrates the spread of HIV through an adolescent population. Acting in the role of epidemiologists, students explore the dilemmas of HIV infection presented by a simulation. Students produce a play, skit,...

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

Students read a story about the life of Russian plant breeder Nikolai I and Vavilov and the national seed bank he established. They research the Irish Potato Famine of the late 1840s and identify the cause for this famine and make...

With colored toothpicks representing genes, youngsters practice passing them through generations of fish and learn about heredity. Consider this as an introductory activity since it does not represent recessive genes with lowercase...

High schoolers engage in a study of science and mathematics with the practice of creating graphs. A guest speaker comes to the class to share statistics from the community and the students are shown how he uses the coordinate system in...

Students investigate evolution in its most fundamental form: the observation of living organisms. By comparing variations that exist among living animals, students formulate their own hypotheses and conclusions about the evolution of...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Use this resource to have your class learn about the cell. This resource walks learners through the construction of a model of a cell. This project is completed in a cooperative learning group, and  reinforces the higher-order...

Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

What an impression fossils make! In this activity, aspiring paleontologists view fossils and construct a timeline to further understand how the lack of natural adaptation caused historical organisms to become extinct. While they...

Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

How is the Earth's weather created? Middle schoolers will explain how the Sun's energy is transformed into different forms. They will perform mathematical calculations of volume, mass, and temperature. They they will explain the...

Students are introduced to biodiversiy. They use a simulation of two forests, one planted with only Douglas Fir trees, and one with diverse species of trees. Students also use the simulation of two forests, one a monoculture of only one...

Octopodes existed for hundreds of thousands of years before humans, yet our eyes share many similarities. Scholars analyze the evidence to determine if the evolution of eyes best fits a homology or analogy model. They discuss the issue...

Third graders consider the habitat needs of living things and how extensive farming in an area can affect the plants and animals of a region. They participate in a simulation to show how changing the habitat in one area can greatly...

Learners explore the interdependence of the animals and plants in tropical rainforests. They explore the importance of conserving biodiversity and tropical food chains. They create a tropical forest food chain and identify species that...

Students examine natural selection, how it works and how it can cause microevolution.  In this evolution lesson students complete a lab activity that shows the effects that natural selection has on organisms.

Students examine the dynamic between animals and humans in the wilderness. They work together in groups share their journal entries when asked to reflect on natural areas.

High schoolers examine the pattern of natural variation in a society. They examine Darwin's theory of evolution and analyze data. They use computer programs to graphically display the variation in organisms.

Students are assigned to bring five flowers. They explore flowers to distinguish different physical features of flowers. They compare and contrast different flowers to determine what features they have in common. Students develop an...
