The National Park Service just turned 100 and what better way to celebrate than with the grand opening of a stunning new addition to the National Mall. The $540 million National Museum of African American History and Culture is adorned with a corona, or scrim, of 3,600 bronze-colored cast-aluminum panels that glow at night from the light within, and was built around a 77-ton, 80-foot-long railway car and other huge artifacts housed in its vast below-ground exhibit space.
This ordinary-looking stretch of road is anything but. Nestled in the mountains of southwest Virginia, the 2.2 mile blacktop contains three bridges, an intersection–and a brain!
Elementary students investigate major landforms (e.g., mountains, rivers) in groups of two. They build a 3D model of a landscape depicting several of these landforms. Once they have built their model, they act as civil and transportation engineers to build a road through the landscape they have created.
Designing, building, and testing bridges can help students develop teamwork and problem-solving skills along with inspiring their interest in engineering. Such hands-on projects also can fuel an interest in reading about bridges. Here are some notable titles that might strike a chord with your budding civil and structural engineers.
When California’s Golden Gate Bridge opened on May 27, 1937, more than 200,000 people strolled or roller-skated across its 4,200-foot causeway. The graceful span quickly became one of America’s most iconic landmarks – including for its safety features and other engineering feats.
In this activity, student teams in grades 8 and up learn about the engineering design process and physical forces by building a bridge from a single sheet of paper and up to five paper clips that will span 20 cm and support the weight of 100 pennies. Like real engineers, teams also have limited budgets and must make trade-offs in materials.
The world’s most visited man-made monument turned 125 this year. Built for the Paris World’s Fair of 1889, French engineer Gustave Eiffel’s famous tower attracted scorn before it opened. But its role as a research lab for weather, aviation, and telecommunications helped ensure its longevity.
Structural engineer Emma Cardini has inspected some pretty impressive facades, including the Chicago Tribune Tower’s ornate spires and the Bridge of the Americas in Panama. Still, nothing compares with the capital bird’s eye view she literally enjoys on her latest job: rappelling down the marble sides of the Washington Monument to assess the damage from late August’s 5.8-magnitude earthquake.
In this short, fun activity for students in grades 2 to 12, teams learn about the engineering design process, including constraints on time and materials, by building the tallest free-standing tower out of pipe-cleaners.
