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.
What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper? The answer, often overlooked, is: soil. With this project you can get all the dirt on soil formation, soil horizons, and the composition of different soils.
Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do slopes have to have certain characteristics, such as a steep angle and a specific material mass? In this geology science project, you will learn about the different types of landslides and the…
Have you ever tried to ride your bike up a flight of stairs? Vehicles with wheels are great at traveling on paved roads or flat ground, but when it comes to stairs or uneven ground in the woods, wheels are not always such a great option. Inspired by real-life all-terrain robots, in this engineering project you will design and build a LEGO® robot that can travel over bumpy ground, through your yard, or even up a stack of textbooks — and almost anything else you can think of!

Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down.
Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment.In this geology science project, you…

When you think of environmental challenges facing the world, the first things that come to mind might be global warming, or loss of biodiversity, since these are often in the newspapers. A serious problem that you may not have heard about is soil erosion. Why is soil so important? What is the danger of erosion? How can we measure soil erosion? What can be done to prevent it? Check out this project and you can start finding answers.
Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far?
The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse…
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.
Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water.
