Considering Trade-Offs and Maximizing Efficiency in a Fast Food Restaurant
Read the Fine Print
Educational Use
Rating
0.0 stars

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.

Educational Use
Rating
0.0 stars

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.

Construct and Test Roofs for Different Climates

Rating
0.0 stars

We design and create objects to make our lives easier and more comfortable. The houses in which we live are excellent examples of this. Depending on your local climate, the features of your house have been designed to satisfy your particular environmental needs: protection from hot, cold, windy and/or rainy weather. In this activity, students design and build model houses, then test them against various climate elements, and then re-design and improve them. Using books, websites and photos, students learn about the different types of roofs found on various houses in different environments throughout the world.

Constructing Sonoran Desert Food Chains and Food Webs
Read the Fine Print
Educational Use
Rating
0.0 stars

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.

Constructing a 3D bathymetry model
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

To prepare for this lab, students read a section of the textbook about observational techniques to measure the seafloor bathymetry as well as the occurrence of common sea floor features, such as seamounts, coastal shelves, mid-ocean ridges, and trenches. In the first lab, groups of students are provided with a bathymetric map, cutting board, sharp edges, and plenty of cardboard. They trace some contours from the map onto tracing paper, and then cut those out of the cardboard to construct a scale model of their given sea floor feature. They attach the sheets of cardboard with double-sided tape, and affix it to the bottom of a rigid box. The box lid has a grid of holes drilled into it. They determine the scale of the map (cm of the model to km in the ocean, for example), and affix the scale to the outside of the box. This concludes the first lab session.

In the second lab session, each team of students is provided with a box from an unknown team. The box is closed, and they do not know what ocean feature lay inside. They use bamboo skewers to take "soundings" at each of the drilled holes in the box lid, and mark their measurements on a piece of graph paper. Then they construct a contour map from the soundings, and try to identify the sea floor feature in the box from a global seafloor topography map that is hanging on a wall.

Students complete guided questions about the process of constructing their 3D scaled model and exploring the unknown ocean.

About Construction Contracting: Business and Legal Principles, 2nd edition by Stuart H. Bartholomew: Exceptionally practical and authoritative, this introduction to construction contracting as it applies to typical, every-day situations explains “theoretical” ideas in terms of what really happens in practice. It emphasizes the more common case law holdings and industry customs that help avoid troublesome legal issues during the completion of a project. - Provided by previous publisher.

0.0 stars

This web page from the National Snow and Ice Data Center contains two related visualizations and supporting information about them. The first visualization gives an estimate of the percent contribution to sea level change since the 1990s from three contributors - small glaciers and ice caps, the Greenland Ice Sheet and the Antarctic Ice Sheet. The second visualization shows the cumulative contribution to sea level from small glaciers and ice caps plotted with the annual global surface air temperature anomaly.

Educational Use
Rating
0.0 stars

Students gain a deeper understanding of how sound sensors work through a hands-on design challenge involving LEGO MINDSTORMS(TM) NXT taskbots and sound sensors. Student groups each program a robot computer to use to the sound of hand claps to control the robot's movement. They learn programming skills and logic design in parallel. They experience how robots can take sensor input and use it to make decisions to move and turn, similar to the human sense of hearing. A PowerPoint® presentation and pre/post quizzes are provided.

Control a Servo with Your Phone Using Bluetooth!

Educational Use
Rating
0.0 stars

Bluetooth is everywhere—from smartphones to computers to cars. Even though students are exposed to this technology, many are not aware of how they can use it themselves to wirelessly control their own creative projects! For this challenge, students build on what they learned during a previous Arduino maker challenge, Make and Control a Servo Arm with Your Computer, and learn how to control a servo with an Android phone (iPhones do not work with the components used in this challenge). By the end of the exercise, expect students to be wirelessly controlling a servo with a simple phone application!

Convection: Blowing Wind
Unrestricted Use
CC BY
Rating
0.0 stars

If there are air leaks in a house, you might expect that their effect would be magnified on a windy day. The wind creates greater air pressure on the windward side of the building and forces air in through the leaks. At the same time, the pressure on the other side of the building is lowered, pulling air out through leaks. This model has a fan blowing against a building. Air motion is shown with arrows. Open and close the "windows" in the building and observe the results.

Convection: Forced Convection
Unrestricted Use

Rating
0.0 stars

Convection refers to transfer of heat by a fluid material (such as air or water) moving from one place to another. The convection is forced if the fluid motion is caused by a fan or a pump while natural convection is the result of density differences.
