This video-enhanced lesson will challenge students to design and conduct scientifically valid experiments to evaluate hypotheses regarding an animal's expected behavior in response to changes in its environment. (Grades 9-12)

Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and quickly to minimize patient trauma, students' surgery time and mistakes are observed and recorded to quantify their performances. They learn about the engineering component of surgery.

This activity will include the students observing the monarch life cycle inside the classroom, a field experience observing monarch life on a milkweed plant and drawing it, and back in the classroom students will make a pop-up book of the monarch's life cycle with a short description on each page.

In this video adapted from the Arctic Athabaskan Council, learn how warmer temperatures in the Arctic are transforming the landscape, triggering a host of effects such as permafrost thawing and insect infestations.

Spreadsheets Across the Curriculum module. Students build spreadsheets to explore conditions that lead to chaotic behavior in logistic models of populations that grow discretely.

In this video produced for Teachers' Domain, learn about MIT professor Cathy Drennan's research into microorganisms that remove carbon dioxide, a greenhouse gas, from the atmosphere.

This activity is a field investigation where students gather leaves from various trees on school property, interpret findings, name tree and leaves, journal activity and develop a new "aha" for nature!

This activity is a classroom and schoolyard investigation where students collect daily temperature and precipitation readings, weather observations, and weekly phenology reports in a phenology binder and in nature journals. Students then analyze this data and compare to recorded values in the Weatherguide calendar.

This article continues an examination of each of the seven essential principles of climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 2 covers the complex interactions among the components of the Earth system. The author discusses the scientific concepts underlying the interactions and expands the discussion with diagrams, photos, and online resources.

In this video segment adapted from NOVA: Becoming Human, learn how the analysis of rock layers and ocean sediments supports the theory that rapid climate change may have jump-started human evolution two million years ago.

In this lesson, students continue their education on cells in the human body. They discuss stem cells and how engineers are involved in the research of stem cell behavior. They learn about possible applications of stem cell research and associated technologies, such as fluorescent dyes for tracking the replication of specific cells.

This video segment from Nature shows the destructiveness of the shark fin and shark cartilage industries.

This field study introduction to biology helps students answer the questions "What is biology" while looking at the biology that can be found in everyday surroundings.

In this video segment from Nature, scientists work to discover why bees are disappearing.

In this video segment from Nature, scientists work to discover why bees are disappearing. [2:39]

Visualize how comets carrying chemicals necessary for life could have made their way to Earth billions of years ago in this video segment adapted from NOVA.

Amino acids, essential ingredients for life, may have been delivered to Earth by comets billions of years ago, as visualized in this video segment adapted from NOVA.

This article describes common misconceptions held by elementary students about the history of the polar regions, fossils, and geologic time. The article provides ideas for formative assessment, teaching strategies, and the National Science Education Standards.

This article describes some common misconceptions that elementary students may have about plants. It also includes suggestions for formative assessment and teaching for conceptual change.

This article discusses misconceptions about birds (and penguins in particular). It provides tools for formative assessment and ideas for teaching correct scientific concepts.
