In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.

A learning activity for the Scoop on Soils book in the Elementary GLOBE Series. Each student will make predictions about the properties of various soil samples. Then they will examine several types of soils and record their observations. Next, they will learn about soil profiles and horizons by both examining a soil sample in a jar and by creating a soil profile flip chart. The purpose of the activity is to provide the opportunity for students to ask questions and make observations about soil and introduce students to the properties of soil and to the concept of soil profiles and horizons. After completing this activity, students will know about soil's different properties and about soil profiles. Students will know that soils have different properties including texture, color, and size. They will know that soil forms layers based on these properties.

In this activity, students will record a list of things they already know about hummingbirds and a list of things they would like to learn about hummingbirds. Then they will conduct research to find answers to their questions. Using their new knowledge, each student will make a hummingbird out of art supplies. Finally, using their hummingbirds as props, the students will play charades to test each other in their knowledge of the ruby-throated hummingbirds. The purpose of this activity is to provide students with information on ruby-throated hummingbirds, provide students with the opportunity to conduct research on hummingbirds in topic areas that interest them, and to provide students with opportunities to share their knowledge with other students. By completing this activity, students will gain knowledge about ruby-throated hummingbirds. They will also gain experience researching a topic of their choosing related to hummingbirds and communicating those results in several different formats.

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of these objects with magnifying lens. The purpose of this activity is for students to learn about observation skills and how tools can help people make observations, what "magnification" means, and to learn that scientists use tools, such as magnifying lenses, to examine objects. Students will be able to identify a magnifying glass and its purposes. They will be able to describe how the same object looks different when using the unaided eye versus a magnifying lens.

A learning activity for the Scoop on Soils book in the Elementary GLOBE Series. Students will make predictions about what they think they will find in a sample of soil. They will investigate the sample and sort out the various items they find. Next they will spend time outside observing one or more sites to see what they find in the soil. After recording and sharing their observations they will create their own stories about the things they found in the soil. The purpose of the activity is to learn about natural things commonly found in soil and how these things impact how the soil looks and feels as well as to introduce students to the concept of decomposition. After completing this activity, students will know about various things found in soil including rocks, critters, roots, and other organic material. They will also understand that animals and microorganisms aid in the decomposition process that contributes organic materials to soils.

A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Students will explore the difference between the three types of contrails, make observations of contrails outside, and record their observations. Fifteen minutes later they will make follow-up observations to see how the contrails they observed have changed. The purpose of the activity is to help students identify contrails and learn to distinguish between the three types of contrails and to understand that contrails are human-made and some contrails become clouds in the sky. Students will be able to (1) identify the three types of contrails; (2) understand that contrails are created by jet airplanes; and (3) understand that some contrails become clouds.

Scientists discuss whether or not endocrine disrupting chemicals, which may cause birth defects and other health concerns, should be controlled in the absence of conclusive proof, in this video segment adapted from FRONTLINE: Fooling with Nature.

Watch students as they conduct an energy audit on a home and gain hands-on experience for a career in the green energy industry, in this video adapted from ATETV.

This course examines the choices and constraints regarding sources and uses of energy by households, firms, and governments through a number of frameworks to describe and explain behavior at various levels of aggregation. Examples include a wide range of countries, scope, settings, and analytical approaches. This course is one of many OCW Energy Courses, and it is a core subject in MIT’s underGraduate / Professional Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

This course explores the theoretical and empirical perspectives on individual and industrial demand for energy, energy supply, energy markets, and public policies affecting energy markets. It discusses aspects of the oil, natural gas, electricity, and nuclear power sectors and examines energy tax, price regulation, deregulation, energy efficiency and policies for controlling emission.

Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!

In this lesson designed to enhance literacy skills, students examine energy forms in moving objects and discover how changes from one form to another move cars through a roller coaster ride.

On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.

See potential energy convert to kinetic energy in this interactive activity from WGBH that shows a roller coaster in action.

The engineering question would be how to create a tool to throw (or roll) the ball farther. Students would test initial throws (or rolls) Then they would be tasked with planning an investigation - creating criteria and constraints (if in grade 5). Students would then be introduced to the news article about the birdstone found in Door County. They would read the wikipedia article about the theories of birdstones, look at a map of where birdstones were said to be found and the tribes that were present. Then students would design an investigation to test how the atlatl worked (the science of energy quantities and transference of energy - depending on the grade) using pictures and art from history and the present. They create an atlatl-type tool and test it against their original throws or rolls. They look at two extensions of the atlatl, one a game that the cherokee played using the atlatl as a symbol and another from modern times, the chuckit. They then discuss whether attributions of the chuckit should be given to the first nations who actually invented the idea. (Criticality)

This course explores the complex interrelationships among humans and natural environments, focusing on non-western parts of the world in addition to Europe and the United States. It uses environmental conflict to draw attention to competing understandings and uses of "natureâ€ as well as the local, national and transnational power relationships in which environmental interactions are embedded. In addition to utilizing a range of theoretical perspectives, this subject draws upon a series of ethnographic case studies of environmental conflicts in various parts of the world.

This course explores the proper role of government in the regulation of the environment. It will help students develop the tools to estimate the costs and benefits of environmental regulations. These tools will be used to evaluate a series of current policy questions, including: Should air and water pollution regulations be tightened or loosened? What are the costs of climate change in the U.S. and abroad? Is there a "Race to the Bottomâ€ in environmental regulation? What is "sustainable developmentâ€? How do environmental problems differ in developing countries? Are we running out of oil and other natural resources? Should we be more energy efficient? To gain real world experience, the course is scheduled to include a visit to the MIT cogeneration plant. We will also do an in-class simulation of an air pollution emissions market.

This course focuses on the thermal, luminous, and acoustic behavior of buildings, examining the basic scientific principles underlying these phenomena and introducing students to technologies and analysis techniques for designing comfortable indoor environments.
