This simulation lets learners explore how heating and cooling adds or removes energy. Use a slider to heat blocks of iron or brick to see the energy flow. Next, build your own system to convert mechanical, light, or chemical energy into electrical or thermal energy. (Learners can choose sunlight, steam, flowing water, or mechanical energy to power their systems.) The simulation allows students to visualize energy transformation and describe how energy flows in various systems. Through examples from everyday life, it also bolsters understanding of conservation of energy. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET).

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!

Introduces the basics of energy from how we measure it, to how it is regulated and priced, to how you can engage in exciting new opportunities for energy efficiency, green architecture, and renewable energy. Recorded in May 2008 by Penn State University for the Local Development Districts of Pennsylvania's Energy Partnership, in Milton, PA.

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 site presents challenges faced by NASA engineers who are developing the next generation of aerospace vehicles. The challenges: thermal protection systems, spacecraft structures, electrodynamic propulsion systems, propellers, and personal satellite assistants. Students design, build, test, re-design, and re-build models that meet specified design criteria, using the same analytical skills as engineers.

Students will choose an engineering sub-discipline of their choice and present information about it to their peers in a presentation style of their choice. The presentation must include some type of multimedia format (Powerpoint, Prezi, Slides, Keynote, etc.)

Students are introduced to genetic techniques such as DNA electrophoresis and imaging technologies used for molecular and DNA structure visualization. In the field of molecular biology and genetics, biomedical engineering plays an increasing role in the development of new medical treatments and discoveries. Engineering applications of nanotechnology such as lab-on-a-chip and deoxyribonucleic acid (DNA) microarrays are used to study the human genome and decode the complex interactions involved in genetic processes.

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines the wedge, wheel and axle, lever, inclined plane, screw, and pulley in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today. In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and selecting a construction site. The six simple machines are examined in more depth in subsequent lessons in this unit.

This unit uses roller coaster design as a method of teaching students about energy types, energy conservation, and the design process. At the end of this Unit, students’ critical thinking and problem-solving skills should be strengthened.

Engineering a Difference follows three teams of engineering students and professional engineers as they work with communities in Ghana, Kenya and Nicaragua to build critical infrastructure. Together, they develop a clean water supply, electricity and a bridge to help these isolated communities thrive. Here are colorful, compelling stories of how engineers make the world a better place.

Engineering principles of nuclear reactors, emphasizing power reactors. Topics include power plant thermodynamics, reactor heat generation and removal (single-phase as well as two-phase coolant flow and heat transfer), structural mechanics, and engineering considerations in reactor design.

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 class explores the interrelationship between humans and natural environments. It does so by focusing on conflict over access to and use of the environment as well as ideas about "natureâ€ in various parts of the world.

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. Students are challenged to apply these techniques and explore the role light, energy, and sound can play in shaping architecture.

In this video segment adapted from NOVA scienceNOW, learn how what you eat, drink, or smoke may affect the instructions your epigenomes send to your genes, and as a result, change how your DNA is expressed.

Students learn that buoyancy is responsible for making boats, hot air balloons and weather balloons float. They calculate whether or not a boat or balloon will float, and calculate the volume needed to make a balloon or boat of a certain mass float. Conduct the first day of the associated activity before conducting this lesson.

In this video excerpt from NOVA, learn about the advantages, disadvantages, and ethical implications of preimplantation genetic diagnosis, or PGD, a technique used to screen embryos created through in vitro fertilization for diseases.

Students explore material properties in hands-on and visually evident ways via the Archimedes' principle. First, they design and conduct an experiment to calculate densities of various materials and present their findings to the class. Using this information, they identify an unknown material based on its density. Then, groups explore buoyant forces. They measure displacement needed for various materials to float on water and construct the equation for buoyancy. Using this equation, they calculate the numerical solution for a boat hull using given design parameters.

In this lesson, the students will summarize their experiences in the Amazon rainforest by developing and presenting a briefing for a T.V. evening news program.
