Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a magnifying glass works, students see how the orientation of an image changes with the distance of the lens from its focal point. They also discover how a prism works by refracting light and making rainbows. And, students investigate the polar nature of light using sunglasses and polarized light film.

How do our everyday actions contribute to our ecological footprint? Can we change our individual actions to be more environmentally friendly and create a more sustainable lifestyle? In this lesson, students will evaluate their own environmental impact using an online tool called Your Plan, Your Planet, and evaluate simple ways to reduce their ecological footprint as an individual or community.

Using a household fan, cardboard box and paper towels, student teams design and build their own evaporative cooler prototype devices. They learn about the process that cools water during the evaporation of water. They make calculations to determine a room's cooling load, and thus determine the swamp cooler size. This activity adds to students' understanding of the behind-the-scenes mechanical devices that condition and move air within homes and buildings for human health and comfort.

This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.

This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.

Students learn about wind as a source of renewable energy and explore the advantages and disadvantages wind turbines and wind farms. They also learn about the effectiveness of wind turbines in varying weather conditions and how engineers work to create wind power that is cheaper, more reliable and safer for wildlife.
Students explore how sound waves move through liquids, solids and gases in …
Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and construction materials when designing sound recording studios, classrooms, libraries, concert halls and theatres.

Students learn about tsunamis, discovering what causes them and what makes them so dangerous. They learn that engineers design detection and warning equipment, as well as structures that that can survive the strong wave forces. In a hands-on activity, students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches a coastline. They make villages of model houses to test how different material types are impacted by the huge waves.
Students learn more about magnetism, and how magnetism and electricity are related …
Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid gasoline-electric cars and their advantages over conventional gasoline-only-powered cars.

For this unit plan, see the old unit calendar (link on left sidebar, click ALT7 tab at the bottom). Once we update this unit to the new Doc template, we will post it here. This is now unit 7, but it used to be unit 4 (we will update file and folder numbering as we continue to revise the units). Thanks for your patience as we work hard this year to update all of the materials to the new unit template and unit/standards arrangements.

The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's principle to change air pressure. Next, students explore the other three forces acting on airplanes thrust, weight and drag. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. The final lessons addresses societal and technological impacts that airplanes have had on our world. Students learn about different kinds of airplanes and then design and build their own balsa wood airplanes based on what they have learned.

TED Studies, created in collaboration with Wiley, are curated video collections 逖 supplemented by rich educational materials 逖 for students, educators and self-guided learners. In Ecofying Cities, speakers reveal ideas about sustainable development (and redevelopment) that aren't all about setting limits, going without or preparing for the worst. Rather, they find solutions in resourceful, hopeful, beautiful communities.
In this lesson, students will first discuss where energy comes from, including …
In this lesson, students will first discuss where energy comes from, including sources such as fossil fuels, nuclear, and such renewable technologies as solar. After this initial exploration, students will investigate the three main types of heat transfer: convection, conduction, and radiation. Students will learn how properties describe the ways different materials behave, for instance whether they are insulators or conductors. Students will complete a crossword puzzle to reinforce their vocabulary in this content area. The class will then focus on the acquisition and storage of energy through the design, construction, and testing of a fully functional solar oven.

People use energy in all aspects of their lives for cooking, lighting and entertainment. Much of this energy use takes place in buildings, such as our homes. To save money and reduce the impact on our environment, many people are reducing their energy use. One way is to hire engineers to perform home energy audits to understand the ways we use energy and identify ways we can conserve energy. In this activity, students act as energy conservation engineers and identify the ways energy is conserved or wasted. They also learn many ways to personally conserve energy everyday.

Students observe a model waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine. Students work as engineers to create model waterwheels while considering resources such as time and materials, in their design. Students also discuss and explore the characteristics of hydropower plants.

Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.
