​Bridges are used for pedestrians, cars, trains, etc. They must span over short or long distances and withstand the forces of nature. There are several types of bridges that are each designed for particular strengths. For example: a beam bridge can take great weight over a short distance, truss bridges take advantage of the strength of the shape of a triangle, while suspension bridges can handle torque and tension across a long distance. When engineers design a bridge they must take the many forces that will act upon the bridge into account. Through hands-on experimentation the concepts of physics inherent in bridge building become clear. This experience gives students a better understanding of a human-made structure that they encounter in cities and towns on a regular basis.​

​Igor Sikorsky designed the first successful helicopter in the late 1930s. His inspiration came from drawings of an aircraft with a spinning wing, drawn by Leonardo da Vinci nearly five hundred years before. This activity help students learn the basic flight principles of a helicopter and test it out, plus have a friendly competition with family members.​

​Ever wonder about the different colors in a bag of M&M’s or Skittles or other multi-colored candy? Are they all the same in each bag? Are there usually more colors than another? This activity will teach students how to make observations and how to do a simple mathematical analysis of the results.​

​Since the beginning of the Industrial Age, air pollution has been a problem. Vehicles and factories certainly add to our quality of life in the convenience they provide daily, but sometimes have a negative effect in our quality of air that surrounds us. In this activity, local air specimens can be collected and the quality can be analyzed by the student. This includes pollution and allergens existing in the air.
