== Introduction to Engineering==
 * Engineering - creating solutions with ideas, processes, tools - exploring the "designed world", different from scientific method and the natural world. distinguishing between the natural and human made world, such as comparing tools with animal body parts, e.g., scissors vs. lobster claws and dog paws vs. rakes. Material properties and the basics of the engineering design process were also included. relationship to core subjects. engineering design process. five technology areas: construction, manufacturing, communication, transportation, and bio-related technologies.

 * hallmarks of good design - useful, intuitive, unobtrusive, durable, and affordable. They are also economical in the sense that they do a lot with a little. That is what makes them elegant.


 * Engineering Design Process * intro to engineering video 7min - LEGO robots > force, friction, torque, speed, careers * Engineering process - identify the problem * explore * design * create * try it out * make it better * process examples - IDEO shopping cart (deep dive design process)

== Perpetual motion machines==

Engineers need to understand basic physics, math and related subjects. Although there are many designs for Perpetual Motion Machines, there is no such thing. Here are several explanations for why there can not be a perpetual motion machine. If you don't understand the explanation, you see why engineers spend so much time learning about what is possible in the real world.


 * Physics 101 For Perpetual Motion Inventors - a review of basic physics for perpetual motion machine inventors, who often misapply elementary physics. For that reason it emphasizes those mechanics principles applicable to machines. However, these are basic to all of physics, and if not properly understood, can adversely affect understanding of everything else in physics.

Redesign Santa's Sleigh
The design magazine Core 77, always has great information, pictures, articles and some crazy contests. The December 2012 issues is no exception. The subject for their regular feature - 1-Hour Design Contest was to redesign Santa's Sleigh. And the winners were...

Read about the winning entry and several others that were selected because they demonstrate some great ideas and provide a good explanation of the improvements that are suggested.

It is time for an upgrade for Santa's transportation. The problem is still the same - delivering presents all around the world on Christmas.
 * What? (Ask questions, understand the need, identify the problem)

There are lots of ways to make improvements. Propulsion, form factor, materials, fuel for example.
 * So What? (Imagine, brainstorm, explore)

Each of the designers provided sketches. These are very effective for communicating the proposed designs. Parts are labeled as necessary for further clarification.
 * Now what? (Plan, design)

This was a design contest, so no one actually built any of the designs.
 * Do It (Create, try it out)

At any point in the Engineering Design Process, you can come up with ideas for improvements. However, some times you just have to take the best design and make it work. Part of the design process is deciding when it is perfect enough, so there will be enough time and resources to build and deliver the design.
 * If this then what? (Improve, make it better)

Ponce Inlet Lighthouse and Fresnel Lens
Florida’s 1350 miles of coastline with its lighthouses played a critical role in the exploration, settlement and development of Florida’s history. Ponce de Leon Inlet lighthouse was built in 1887 and is the only Florida lighthouse listed as a National Historic Landmark and is the second tallest brick tower in the United States.

Design Challenge : Fresnel's little light

Fueled by kerosene, this little light could be seen for more than 18 miles out in the ocean because it was magnified by a special Fresnel (pronounced Fra-NEL) lens. Each question corresponds to a step in the Engineering Design Process.

Engineering Toy to Empower Girls
Core 77 October 2012..
 * celebrate the development of a toy that is meant to promote the education of girls and more specifically, their learning in science and math.


 * Debbie Sterling was discouraged by the stereotypes that suggested that boys should play with Bob the Builder while girls were left to dress up Barbie. With 89% of male engineers in her program at Stanford, it was obvious that there was a gender gap in the field. But more notably, Sterling was aware that there was a significant gap in the formative space of play. Because of this, she was motivated to spend a year of research with over 100 children in order to develop GoldieBlox: a construction toy for girls.

Design Challenge : Engineering Toy for Girls

The idea is to introduce new engineering principles with a story, including lessons around wheels and axles, pulleys, force and friction. Each question corresponds to a step in the Engineering Design Process.


 * Ask (What? Ask questions, understand the need, identify the problem)


 * Imagine (So what? Imagine, brainstorm, explore)


 * Plan (Now what? Plan, design)


 * Create (Do it. Create, try it out)


 * Improve (If this then what? Improve, make it better)

Boys build stuff. Girls like to read, but girls need to understand and experiment with spacial relationships and simple machines if they are to become engineers.
 * What? (Ask questions, understand the need, identify the problem)

Simple machines are, well..., simple so they can be made and used in all sorts of ways. Some will appeal to girls. Colors help. A good story with illustrations is likely to interest girls.
 * So What? (Imagine, brainstorm, explore)

Deciding what works can be the work of one engineer or designer. For some designs, the developer works with dozens of variations and has them tested by hundreds of target users - kids in this case.
 * Now what? (Plan, design)

In order to produce a commercial product to sell in toy stores, the developer had to pay to have the toys built. Because there is a lot to set up to manufacture these toys, they have to make at least 5000 toys. That is very expensive for a new company just getting started.
 * Do It (Create, try it out)

The first toy was successful, so they will be adding more new toy designs soon.
 * If this then what? (Improve, make it better)

== Foam Plate Glider with Flaperons == Build a model FPG-9. Get others in your troop or patrol to make their own model, then organize a competition to test the precision of flight and landing of the models.


 * video, pattern resources

http://engineering.wikia.com/wiki/Lift_%28force%29 Some of the simplest models effectively demonstrate complex engineering challenges. This glider design is easy to make from low-cost supermarket materials.

Design Challenge : straight and level This simple design provides all the control surfaces that are incorporated into modern aircraft. Work through the design and build process for the Glider, to reverse-engineer the pattern. Each question corresponds to a step in the Engineering Design Process.


 * Ask (What? Ask questions, understand the need, identify the problem)


 * Imagine (So what? Imagine, brainstorm, explore)


 * Plan (Now what? Plan, design)


 * Create (Do it. Create, try it out)


 * Improve (If this then what? Improve, make it better)

Come up with a better way to demonstrate the forces and control surfaces for glider (un-powered) flight.
 * What? (Ask questions, understand the need, identify the problem)

People have been making paper airplanes as the demonstration model. However, these are either poor fliers or very difficult to make accurately enough to demonstrate the differences that small changes in the structure of the plane make. Consider some other materials. They must be cheap and easily available. The design must clearly show how the parts of the plane's wing and tail change its flight.
 * So What? (Imagine, brainstorm, explore)

These model gliders will be made by kids of all ages and abilities. Make the design simple so everyone can make one that works.
 * Now what? (Plan, design)

Provide instructions that are clear so that anyone can follow them. Tell them what the final glider looks like and how it is supposed to work.
 * Do It (Create, try it out)

Some people follow directions. Some people don't. Some people prefer to look at pictures. Everyone should be able to make a glider that works.
 * If this then what? (Improve, make it better)
