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...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

In this environment worksheet, young scholars complete a series of multiple-choice and short-answer questions on genetics, populations, and cell structure.

Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

Students explore the reasoning and experimental approaches to mutations. They expose a culture of E. coli to virulent bacteriophage and observe whether mutations of the cells existed previously or if the bacteria mutated as a response...

Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

In this environmental worksheet, students complete a series of multiple-choice and short-answer questions on cell types, cell division, chromosomes, and plant species.

Students demonstrate how organisms adapt to their environment. They examine prey and predators, natural selection, and adaptations by representing oyster morph.

Explore the concept of evolution and cell biology; your class can work in groups to use the internet to view websites on evolution, take a quiz, and complete a lab activity.

Gene switches work similarly to light switches in controlling one feature of their environments. Scholars study the Pitx1 gene in a specific type of fish. They learn the different ways this switch controls various body parts and...

Students identify where mutations might occur and examine what effect those mutations will have through class discussion of DNA replication and cell division. Students then differentiate between mutations that affect individuals and...

Ninth graders construct and conduct a laboratory experiment illustrating the transfer of mutations. They compare and contrast natural selection in organisms with long and short reproductive cycles.

Students explain the roles of mRNA, tRNA and ribosomes. They explain how mutations can occur in an individual. Students simulate parts of a cell to access about the process of protein synthesis.

Students 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.

Students identify and illustrate how changes in DNA cause mutations and evaluate the significance of these changes. They illustrate a chromosomal mutation such as duplication, deletion, inversion, and translocation.

In this adaptations worksheet, young scholars read about 3 species that have changed over time to adapt to their environment. Students design a squirrel that has adapted to an island habitat that young scholars are assigned. They...

Students participate in a contrived natural selection simulation in which they build and modify simple paper airplanes. They study divergent and convergent evolution and how it is isolated in sub-populations.

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...
