Students are introduced to the idea of improving efficiency by examining a setting that is familiar to many teenagers fast food restaurants. More specifically, they learn about the concepts of trade-offs, constraints, increasing efficiency and systems thinking. They consider how to improve efficiency in a struggling restaurant through delegating tasks, restructuring employee responsibilities and revising a floor plan, all while working within limitations and requirements. Finally, students summarize and defend their suggested changes in argumentative essays.

This is an activity about identifying constellations. Learners will look for constellations in the Sky Tonight online program, draw images of these constellations, and attempt to find them in the night sky. Learners will also be asked to make connections between the shape of a constellation and its namesake. This activity requires the use of a computer with Internet access. It also requires access to the clear night sky. This activity is Sky Tonight Activity 1 in a larger resource, Space Update.

Students use simple household materials, such as PVC piping and compact mirrors, to construct models of laser-based security systems. The protected object (a "mummified troll" or another treasure of your choosing) is placed "on display" in the center of the modeled room and protected by a laser system that utilizes a laser beam reflected off mirrors to trigger a light trip sensor with alarm.

Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and what type of consumer; herbivore, omnivore, or carnivore. Students are provided with a list of Sonoran Desert species and asked to construct, within their groups, several food chains. These food chains are then be used to construct a food web. In order to complete this activity, students must first research the individual species to understand their feeding habits.

Chandra Garcia uses continent-shaped puzzle pieces to teach her students about continental drift. Working in small groups and using fossil evidence, students must work cooperatively and find consensus among themselves to build their arguments.

Students use the robot paths they documented during the associated Robots on Ice Engineering Challenge activity to learn about and then make artwork. During the previous activity, students recorded the path of their robots through a maze in order to collect data during a remote research simulation. Now, they take a new look at the robot paths, seeing them from an art perspective as continuous line drawings. Students learn about Picasso’s famous works of art that used the same technique. Then they learn the artistic definition of a line and see examples of how it is used in different art pieces; they practice making continuous line drawings and then create sculptures of their drawings using colorful wire. A PowerPoint® presentation is provided to guide the activity.

Students teams design and build shoe prototypes that convert between high heels and athletic shoes. They apply their knowledge about the mechanics of walking and running as well as shoe design (as learned in the associated lesson) to design a multifunctional shoe that is both fashionable and functional.

Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.
PHYSICAL SCIENCE, STEM CAREERS In this video, learn from chemical engineers Laura …
PHYSICAL SCIENCE, STEM CAREERS In this video, learn from chemical engineers Laura and Wade about what it takes to become a chemical engineer and why it's a great career. Find out how chemical engineers do things like save the environment, take waste and make it useful, and solve real-world problems every day.
ABOUT THE SCIENCE What do disposable diapers, soda, hydrogen fuel cells, aluminum, penicillin and snowboards have in common? They were all invented or further processed by a chemical engineer! Are you someone who likes to solve problems? Do you like making something new? Do you care about the environment? If so, being a chemical engineer might just be for you! As an engineer in this field, you get to apply chemistry to the industrial process to make things. It takes technology, innovation, and ideas to help generate an end result. An example of this is through making textiles out of weeds! As a chemical engineer, first you would put the weeds through a processing system, have them pulped, put through an extruder to create a fiber, and then voila! You can use that to create textiles. To ensure chemical engineers are being friendly to the environment, their decision making always considers renewable resources.

Students learn the meaning of preservation and conservation and identify themselves and others as preservationists or conservationists in relation to specific environmental issues. They use Venn diagrams to clarify the similarities and differences in viewpoints. They see how an environmental point-of-view affects the approach to an engineering problem.

This is a set of three, one-page problems about how astronomers use coordinate systems. Learners will plot a constellation on a coordinate plane and/or plot the route of Mars Science Lab (MSL aka Curiosity) on the surface of Mars. Options are presented so that students may learn about the MSL mission through a NASA press release or about the coordinate plane by viewing a NASA eClips video [7 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

This lesson introduces students to the idea of biomimicry or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.
