How can heat power an engine? Scholars observe a heat engine working and control variables to determine the most efficient setup. They change the amount of heat input as well as the stroke length. Energy efficiency numbers prove the...

Investigate life along the Old Spanish Trail! They visit websites and identify the history and environment. They create journals, dramatic enactments, and maps to discover the role individuals played in society. They also explore the...

Discover a world too small to see. In the lesson, young scientists learn about nanotechnology and brainstorm ideas for new applications of it. They perform an activity to determine how surface area changes when objects are made smaller...

Build a bridge to learning in a STEM-aligned unit about urban infrastructure. Young engineers explore the many aspects of civil planning and design in a five-day unit. Content includes the challenging aspects of balancing building with...

Students explore the ocean depths. For this scenario based lesson, students pretend they are on a submarine in an unknown part of the ocean. By using clues the class discusses and determines where they are in the ocean. They follow up...

Students explore engineering by participating in a mechanical class activity. For this simple machines lesson, students identify many simple machines that allow them to perform tasks easily each day. Students collaborate in small groups...

Learners review their knowledge on the First Amendment. After reading an article, they identify specific church and state issues. Using the Internet, they research President Bush's proposal from a specific point of view. They summarize...

Learners design and build model houses, with an emphasis on waterproof roofs. They perform tests to see if their models are as waterproof as they think.

Students explore physical education by completing a quiz in class. In this engineering lesson, students identify different ways engineering has made sports safer such as stronger padding and helmets, stronger equipment and smarter...

Students build a model rocket. In this model rocket lesson, students explore a rocket launch cycle. Students investigate the laws of physics for each part of the launch. Students build model rockets and launch at school.

Students read a New York Times article associated with the issue of the decoding for genomes, the creation of life in scientific laboratories and various genetic engineering topics. They present speeches of the pro's and con's of these...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Class members are transformed into explorers as they work in groups to locate hidden items and map their journey along the way. They then leave clues for other groups of students to follow, and ultimately discover how past explorations...

Students simulate life in space aboard the space shuttle. In this space exploration lesson, students work in small groups to model life aboard the space shuttle. Each student is given a job, conducts Internet research on space, and...

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

Operating a vehicle remotely can be difficult, especially when the vehicle is on another planet. Young engineers get a feel for some of the real-world challenges as they work to program their rovers (blindfolded group members)...

Young hydrologists observe a waterwheel which helps them investigate the transformations of energy that occur when the blades of a hydro-turbine are turning. They work together in pairs and pretend to be engineers who are building a new...

Students discuss the terms exploration and technology. They read about the MESSENGER, Mission to Mercury, and answer questions. Next, they design and plan the technology for a space mission using an online interactive activity.

Seventh graders play a debate game as they explore the concept of alternative transportation fuel. They evaluate the advantages or disadvantages of using biofuels. Multiple resources, such as videos, PowerPoints, and websites are...

Meant to be a simulation of a deep-sea exploration, this requires that another lesson be completed first. In that lesson, titled "Animals of the Lost City," marine biology buffs construct murals of benthic communities. In this lesson,...

Students explore the ocean rift habitat off the Galapagos through an audio expedition, Internet research on deep sea animals, an explorer game and simulation of the exploration of the deep sea bottom. They focus on the actual NOAA...

Middle schoolers plan a mock mission to Mars. In this space science lesson, students work in cooperative groups and select one experiment to take on their mock mission. Middle schoolers create a mission plan form and send a proposed...

Japan is one of only a handful of countries that constructs buildings that are almost earthquake proof. The 13th lesson in the 20-part series challenges scholars to build structures to test against earthquakes. With limited materials and...

Students are "Energy Detectives" working for an engineering firm that does energy evaluations at schools. In teams, they locate energy sources around the school, and record their findings on an Energy Detective Worksheet.
