Chapter 4

Engineering

Engineering is all about applying science and math knowledge to help solve problems and reach goals. These problems and goals are important for improving life on our planet. A group of experts from around the world came together as part of the National Academy of Engineering (NAE) to make a list of what they called “the Grand Challenges for Engineering in the 21st century.” This list includes important life-changing goals like making solar power better. Right now only about 1 percent of the world’s power comes from solar energy, but this number has the potential to be much higher. The sun provides more energy in just one hour than people worldwide use in a year!

The experiments in this chapter are a step in the direction of helping to engineer a better future. You will construct better buildings using bioglues , create a candle-powered boat, and even design a rock-hopping robot! All these experiments follow the engineering design process in which you ask questions, imagine solutions, make a plan, create your idea, and improve your design through creative problem solving. The engineering design process is a lot like the scientific method, with one exception. The scientific method and the engineering design process have two different goals. The goal of the scientific method is to figure out how the natural world works. The goal of the engineering design process is to solve a problem using limited materials and a budget. The experiments in this chapter all focus on solving a problem.

You probably have everything at your house to complete these experiments. For the Make Your Own Molds experiment , you will want to check your kitchen for food-safe glycerin and unflavored gelatin. If you don’t have these items, you should add them to the shopping list for your next trip to the grocery store.
