This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online simulation software to analyze the distribution of load-bearing forces in each design. Then you'll build and test prototypes of each design.

We've all heard that hurricanes draw their immense power from warm ocean waters. Of course, many factors contribute to the formation and growth of a hurricane, but can we expect to find that the warmer the water, the stronger the hurricane will be? This project shows you how to use online data archives to investigate this question. Read more

When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a global network of seismometers to find out for yourself. You will make your own seismograms using the Global Earthquake Explorer program, and then use the seismograms to determine the location of earthquake epicenters. Read more

If you've ever so much as watched a news clip about a hurricane, you probably know that hurricanes draw their power from warm ocean waters. If that is true, does it mean that hurricanes actually cool the ocean down when they pass through? Can the amount of cooling be measured? Is it proportional to the strength of the hurricane? Find out using data that you can collect yourself using online archives. This project shows you how. Read more

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more

Although fractal images can be intriguingly complex, fractals are more than just pretty pictures. In this project, you'll explore the mathematical properties of the famous Mandelbrot (illustration on the Background tab) and Julia sets. You'll learn about how these images are generated, and about the relationship between the Mandelbrot set and the Julia sets. Read more

Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more
