Civil engineering is a field for problem solvers. From setting up water systems for drinking and irrigation to major transportation systems like highways, airports, subways, and railroads, civil engineers take on big challenges. In today's world, civil engineers also face big challenges: providing the modern infrastructure for a growing human population, and finding ways to do this that are environmentally sound, safe, and cost-effective. Experience what it is like, on a smaller scale, to tackle these problems with one of our student-sized civil engineering projects.
Skyscrapers are impressive structures. What does it take to design a building so tall? Engineers use strong materials and innovative design to push the limits of gravity. In this experiment you will use LEGO® components, rubber balls, and a 3-ring binder.

Bridges are big and beautiful structures, but they also need to be safe for the people who cross over them every day. Building a bridge that is safe and secure is a challenge to civil engineers. But the job is even more challenging if you live in earthquake country! Find out how engineers are solving this problem as they build a new bridge over the San Francisco Bay in California. Try some of your own Bay Bridge designs. Will your bridge design take the shake of a quake?

The wind is a powerful force, enough to erode whole hillsides over time. Building structures in windy environments challenge civil engineers with special safety concerns. A wall in a windy area can either shield you from the cold or fall down on you. Learn a few tricks on how to design walls in windy places.

Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold…

Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out.

Predict how tall you can build a tower using only two sheets of newspaper as building material. You can't use tape, glue, staples, or anything else, just two sheets of newspaper. You can tear, bend, cut, or fold the newspaper. Try it out and see how close you can come to your prediction. Can you beat your prediction? As you're building, you may come up with ideas to make a better tower. Try them out! (It's not like the materials are expensive!) Here are some variations you might want to…

Have you ever been in an earthquake? What did it feel like? Did you jiggle back and forth? Up and down? Was there a jolt? Or a rolling motion? Come build a house Hansel and Gretel would love to eat, a special table to shake it on, and see how different soil types can amplify shaking.

Have you ever looked up at a skyscraper and thought "That is so cool!"? Building a skyscraper, or any structure, is more than just building the walls, windows, and floors. All structures require a foundation to keep them from falling down. This is especially important when a structure is built on a hill or on a slope. In this science project, you will build a tower of Lego® Duplos® on slopes with different angles. You will investigate how deep you have to dig the foundation for each…

Have you ever seen a geodesic dome? Geodesic domes are approximately sphere-like (or partially sphere-like) structures made up of interconnected triangles. A famous geodesic dome is Spaceship Earth at EPCOT in Walt Disney World, Florida, but geodesic domes are also commonly found as climbing domes at playgrounds. In this science project, you will get to build a geodesic dome using rolled-up newspapers and tape. How much mass do you think your dome will be able to support? Build one and find out!

This project is inspired by the Banaue Rice Terraces, 2,000 year old structures carved into mountainsides in the Philippines. See if you can recreate the water flow of this ancient marvel, often called the Eighth Wonder of the World, using just household materials! The is over but you can still try out the project and compare your design to the high scores, or use the idea for a science fair or classroom activity.
