Students engage in a lesson that is concerned with the art of photography. They conduct research using the Internet and other resources. The students use the lesson plan to create context for using analytical language for class discussion.

In this online interactive English vocabulary skills worksheet, students respond to 13 multiple choice questions that require them to fill in the blanks in sentences with the appropriate prepositions.

Students analyze a quote written on the board by John Muir. They brainstorm ideas from the quote and discuss the interpretation of the quote and answer questions regarding the Forest Service as a Profession.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Young scholars create a simple machine that includes a cart and lever system that could have been used to build the ancient pyramids. For this simple machine lesson, students learn about the wheel and the axle as simple machines that...

Learners study laboratory protocol for hemagglutination experiments.

Students explore evolutionary processes and theories using the spotted fish applet. They observe what happens to fish in a closed environment with both food and predators. Students run the model several times and answer questions about...

Students articulate in written and oral formats that bacteria can be found living everywhere. They explain in written and oral formats why the immune system is necessary. Students are presented with an opportunity to see bacteria alive...

For this Soviet Union worksheet, students read a 2-page selection about scientific work in the country and then respond to 4 short answer questions based on the selection.

Gene pools can change as a result of genetic drift and other mechanisms. This tutorial will investigate how gene pools change and evolve.

When a population is in Hardy-Weinberg equilibrium, it is not evolving. Learn how violations of Hardy-Weinberg assumptions lead to evolution.

Examine the six major mechanisms of evolution and evolutionary processes.

A description of the process of evolution explaining the Hardy-Weinberg Principle and the mechanisms that cause it. Also the website contains links for lessons on simulation of the natural selection process in the classroom and how the...

A multiple-choice quiz on the mechanisms of evolution.

EvoDots lets the user explore the mechanism of evolution. The program creates a population of dots. The user is a predator. As the dots run around the screen, the user eats them by clicking on them with the mouse. After the user has...

Constructing phylogenetic trees may be a daunting task for students, but this lesson plan is a simulation of what molecular biologists must do to determine relationships. This plan is for students who have a good grasp of DNA structure...

Students observe natural selection in action and investigate the underlying mechanism, including random mutation and differential fitness based on environmental characteristics. They do this through use of the free AVIDA-ED digital...

The human eye is an amazing mechanism, able to detect anywhere from a few photons to a few quadrillion, or switch focus from the screen in front of you to the distant horizon in a third of a second. How did these complex structures...

Teach aliens about evolution as you play this game, and review your own understanding in the process. Topics covered include evolutionary mechanisms, evidence of evolution, natural selection, reproductive isolation, population genetics,...

Macroevolution and microevolution are defined, along with mutation, migration, genetic drift, and natural selection, which are "established mechanisms of evolutionary change."

This lesson plan, designed to accompany the PBS series "Life of Birds," explores how environmental pressures influenced the evolution of wings, how natural selection resulted in the diversity of bird species, and the mechanics of bird...

Viral genomes are the fastest evolving entities in biology, mainly because of their short replication time and the large quantity of offspring released per cell infected. Evolution occurs by several mechanisms: Random mutation,...

Article explaining what viruses are, their evolution, taxonomy, morphology, and replication. Also covers mechanisms by which viruses cause disease, how they can impact on plants, and the potential and real benefits we get from...

Laurence Moran discusses one of the most important mechanisms of evolution, Random Genetic Drift.
