Students examine a PBS special about howler monkeys as an introduction to scientific forensic investigative methods. In groups, they conduct a host of experiments containing clues which point to discovery. By challenging assumptions,...

Students answer the question "How are the concepts and processes I examine in Biology relevant to my other classes, to my life, and to my community?" This assignment has students actively involved in the intellectual work of location,...

Students discuss ten important Pennsylvania hardwood trees, examine characteristics of each tree species, evaluate economic and ecological importance of hardwood trees, and recognize at least two characteristics of each species.

Students investigate the effect that sterile and non-sterile environments have on growth of microbes. In this biology lesson, students observe the appearance of sample test tubes for 7 days. They explain why some test tubes' appearance...

Learners use scientific methods to investigate the concept of DNA. They observe the DNA of human cheek cells. This is done with the use of a lab experience. Students record their observations and reflect upon on how each organism is...

Young scholars discuss methods used by forensic scientists and the basics of DNA and how it can be used to identify an individual after reading an article from The New York Times.

Students work in groups as they read chapters of Charles Darwin's, Voyage of the Beagle. They take notes on the chapter and in their group make a timeline of the chapter. They tape the timelines together in order to depict the entire...

Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.

Students investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...

Students observe a planaria without a microscope and with a stereoscopic microscope. They draw the planaria and describe its motion and eating habits. Students research planarias various body systems and behavior. They design an...

Students analyze information and draw conclusions about the reality of human life expectancy; the battle between health care technology and our own internal time clocks. Students answer questions such as "Why does aging occur and can...

Students discover new ways to preserve the ecosystem by completing graphic organizers.  In this environmental lesson, students read an article from the Natural Inquirer in small groups and fill out a graphic organizer based on the...

Students investigate the monarch's searching behavior and ability to find food. They determine whether or not a caterpillar can find food in a simple Y-shaped maze. They record and graph or chart the data from several attempts using...

Students learn about transect lines through a study of marine debris.  In this marine debris lesson, students calculate the items on a transect line and graph them.  Students complete a category worksheet.

High schoolers use hands-on field-testing of authentic application from principles pertaining to: Psychology- A. Develop a positive, can-do attitude with a high degree of self-reliance that is transferable to human interactions outside...

Students, in groups, develop their hatcheries, working cooperatively in its design and construction. The lessons begin with the introduction to Artemia as a primary food source of many aquaculture species during their larval stages.

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

High schoolers demonstrate an understanding that the same data can lead to different interpretations and conclusions and that different interpretations and conclusions are not necessarily wrong, but can be useful in developing other...

Pupils research a NASA Website and record information about an assigned city's tropospheric ozone residual monthly climate. In groups, they graph the information for the past year. They form new groups and compare their city's...

Students examine each soil sample and record observations. For this biology lesson, students design an experiment to test soil flow rate. They write a lab report about the experiment.

Students explore the behavior of crickets during courtship. They measure the number and types of interactions between household crickets. Students discriminate between quantitative and qualitative observations. They collect data to...

Students examine worm habitats. In this animal habitats instructional activity, students participate in a lab activity that requires them to explore the adaptations that earthworms make to their environment.

Tenth graders conduct a critical analysis of current evolutionary concepts. They describe how scientists continue to investigate theories. Students examine examples with experimental data that suggest alternative methods of species...

Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.
