Do you enjoy singing contests like American Idol? Well, male songbirds have their own version of a singing competition that has been going on for thousands of years, and classical musical composers have been taking notes! In this music science fair project, you'll investigate the different instruments composers have used to imitate or create impressions of bird songs and bird calls.

In this project you'll learn about how digital image files are encoded, and how digital images can be compressed so that the files take up less storage space and can be transmitted more quickly. You will also measure the quality of compressed and uncompressed images, which will give you important insights into the tradeoffs between file size and image quality.

Graphical methods of data presentation are a key feature of scientific communication. This project asks the question, "What's the best way to compare the land area of states: a map or a bar graph?" You'll be measuring performance on two different visual discrimination tasks: comparison of areas vs. comparison of position on a common scale. Which method is more accurate? Which method is faster? This project will get you thinking about how to find the best way to communicate scientific…

You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature?

Spoiler alert: Your physics textbook might contain an inaccurate equation. Are you shocked? Let us explain — many questions in your physics textbooks are simplifications of how things behave in the real world. For example, in physics textbooks, springs are usually modeled with the equation Force = stiffness x displacement:
Equation 1:

What do you think about killing vampires? No, no, not the kind that drink people's blood, but the
kind that suck your power and money away. Equipment like televisions, computers, printers, and fax machines
all use electricity to operate, of course, but do you realize that this equipment might still be sucking electricity from the wall, even when you think it's turned off? These electricity-suckers are called vampire loads. In this science project, you will investigate how much power these…
