1. Table of Contents

SO YOU WANT TO GET STARTED WITH ENGINEERING! Engineers are people who design and invent new products and processes. They improve life by building solutions to problems in the natural world. They use tools and technologies in their daily work. And they team up on projects with scientists, government officials, and business people.

Many grand challenges await you in the world of engineering: making better use of solar energy; creating new types of transportation; securing cyberspace; designing better medicines; providing the world with clean drinking water; applying the function of the brain to computers; inventing new ways to teach people; and improving virtual reality. Its never too early to start, so roll up your sleeves and get ready to work as a junior engineer!

Engineering is a hands-on field. When you work in engineering, you will use your body as much as you use your brain. In this book, you have opportunities to do both! Sometimes you'll use your eyes and your fingers to work in a small, careful way. An example is using a needle and thread to sew a wearable electronic circuit with LED lights and a battery onto a baseball cap. Other times, you'll use your lungs, legs, and arms to work in a big, athletic way. An example is blowing up balloons to serve as air bags on a Mars lander, and then running up the stairs and hurling the lander off the second floor to (what I hope is) a soft landing on the planetary surface below.

But you'll also use your brain quite a bit. You'll do some online research to learn about engineering projects that have been done before and how they succeeded or failed. You'll use computer simulations to tinker with a product or a process to learn how it operates. In this way, you can try different ways of building or different ways of conducting a process before you do them in the real world. You'll brainstorm and draw design plans in your design notebook and then write down how those plans perform and how you can improve them.

Heres what you need to do the projects in this book:

• A computer running a modern version of a Windows or Mac OS X operating system
• A reasonably fast Internet connection
• Some household items, such as foil pans, scissors, a trash bag, tape, a marble, a meter stick, clear plastic wrap, tape, a dog leash, kitty litter, cotton balls, an ear syringe, a thermometer, liquid dishwashing soap, and a kitchen scale (plus a few more items)
• Some food items, such as marshmallows, graham crackers, canola oil, and assorted pasta
• Some home improvement store items, such as foam tubing, PVC elbows, string, sand, and perlite
• Some craft store items, such as craft foam, pipe cleaners, hay, a hot-glue gun, feathers, and faux fur
• One specialty purchase (LilyTwinkle electronics kit for $20) and, optionally, the use of a 3D printer
• Some safety gear, namely goggles, protective gloves, and a face mask

• One design notebook, which can be any notebook with paper or graph paper, to draw designs and write evaluations of your products and processes and how to improve them; you can also print photos of your work and paste them into your notebook (optional)

Every project follows the Engineering Design Cycle, or Engineering Cycle. This process is different from the Scientific Method, which you probably learned in school. I explain the Engineering Cycle in .

My design sketches are meant to spark your imagination. Your engineering designs may look very much the same or very different from my designs. Your ideas are valuable and I want you to have faith in them. Brainstorm, invent, and build!

Finally, every project wraps up with a section called the Iron Triangle of Engineering. This section helps you think about what real engineers consider when doing that type of project.
