How Tweet It Is: Bird Songs in Classical Music
Science Fair Project Idea
Scientific Method
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. Read more

Can you recall how a piece of warm apple pie or a cup of hot chocolate milk tastes when you let it cool? Maybe you even prefer to have these treats at room temperature. Why is this? Can flavor change even when you are not adding ingredients, cook or bake it? Try this activity and discover how temperature influences flavor! Read more
Hula Hoop Science: Weekly Science Project Idea and Home Science Activity Spotlight
Blog Post
In this week's spotlight: a pair of science projects perfect for burning off some energy and getting your "spin" on. What is the secret to a good hula hoop? Experiment with the weight and size of different homemade hoops to see how each affects your ability to keep a hoop in motion. What's the best combination? Can you hula hoop longer with a lighter or heavier hoop? Why? Motion Mania: Applying Physics to Hula-Hooping (full Science Buddies Project Idea) Swiveling Science: Applying… Read more
Humidity and Weather
Science Fair Project Idea
Scientific Method
If you live in a humid environment, then you know that summer is not only hot, it is downright muggy. You can test the effect of humidity on temperature by measuring the temperature and humidity in your bathroom while running the shower. You can also use historical weather data to compare average seasonal temperatures in humid (e.g., Florida) and dry (e.g., Arizona) regions. How does humidity relate to temperature? Pressure? Why do humid environments tend to be coastal or tropical? How does… Read more
Hurricanes and Climate
Science Fair Project Idea
Scientific Method
The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. The goal of this project is to study the historic relationship between the El Niño/Southern Oscillation (ENSO) and the number and strength of hurricanes, either in the Atlantic or Pacific Oceans. Since… Read more
Ice Cream Science: Weekly Science Project Idea and Home Science Activity Spotlight
Blog Post
In this week's spotlight: a food science family science experiment and independent student science fair project that takes a deeper look at the chilly process of making ice cream. You can make your own ice cream using one of a variety of shaking or rolling processes, including using a baggy to hold the ingredients! How does adding salt to the ice mixture used to freeze the ingredients affect the process? Make your own ice cream to find out! Chemistry of Ice-Cream Making: Lowering the… Read more
Image Compression
Science Fair Project Idea
Scientific Method
Compare the strengths and weaknesses of different digital image formats. How does the amount of compression affect a JPEG image? What happens when you save a JPEG image multiple times? Read more
Image Compression vs. Image Quality: Finding the Best Tradeoff
Science Fair Project Idea
Scientific Method
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. Read more

Ever wonder why most people love patterns? We see patterns in art and music, and also in our daily lives. Patterns can provide a sense of order and can make a hectic-looking world a little more manageable. They are the basis of many assumptions and predictions. We assume we will have lunch at noon, as that is what we always do; we predict thunderclouds will bring rain, as these clouds always bring rain; and you might expect your parents to get mad when you disobey, as that is what has followed… Read more
Interpreting Area Data from Maps vs. Graphs: An Experiment in Visual Perception
Science Fair Project Idea
Scientific Method
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… Read more
