When asked to list some strong materials, people think of steel, concrete, and wood. In this activity, students learn about the force of compression and how it acts on structural components through a hands-on group problem. Using everyday products such as paper, toothpicks, and tape, students construct a structure that will support the weight of a…

In this activity, students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In Part One, students play the role of molecules in a beam subject to various loading schemes. In Part Two, students break foam insulation blocks by applying…

After a discussion about what a parachute is and how it works, students create a parachute using different materials that they think will work best. They then test their designs, which is followed by a class discussion to highlight which paper material worked best. This activity requires a 60-minute time period for completion. (Author/SOE)

In this activity, students investigate the accuracy of sundials and the discrepancy that lies between "real time" and "clock time". The position of the sun is tracked over the course of a relatively short period of time as students make a shadow plot, a horizontal sundial, and a diptych sundial. This activity requires…

In this activity, students reinforce an antenna tower made from foam insulation so that it can withstand a 480 N-cm bending moment (torque) and a 280 N-cm twisting moment (torque) with minimal deflection. One class period is used to discuss the problem, run the initial bending and torsion tests, and graph the results. The second class is used for…

In this activity, students learn about composite materials, tension as a force, and how they act on structural components through the design and testing of a strip of plastic chair webbing. This activity requires a 60-minute time period for completion. (Author/NB)

Rube Goldberg is famous for his very complex machines that accomplish everyday tasks. In this activity, students design and build a Rube Goldberg machine that will accomplish a simple task in no less than 10 steps. This activity requires a 120-360 minute time period for completion. (Author/SOE)

In this activity, students build a city out of sugar cubes, bouillon cubes, and gelatin cubes. The city is then put through simulated earthquakes to see which cube structures withstand the shaking the best. This activity requires a 50-minute time period for completion. (Author/SOE)

Working in teams of four, students build a tetrahedral kite following a specific set of directions and using specific provided materials. Students use basic processes of manufacturing systems-- cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control--to manufacture a complete tetrahedral kite within a given…

Towers have been a part of developing society for centuries. In this activity, students investigate towers that serve a variety of purposes. Student groups build three types of towers, engineering them to hold an egg one foot high for 15 seconds. This activity requires a 60-minute time period for completion. (Author/SOE)

In this activity, students work with specified materials to create aqueduct components to transport two liters of water across a short distance in the classroom. The goal is to build an aqueduct that will supply Aqueductis, a Roman city, with clean water for private homes, public baths, and glorious fountains. By introducing various ideas and…
