Human-Robot Interaction: Do Looks Matter?

Science Fair Project Idea

Scientific Method

Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. 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

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

Investigate Native Plant Evolution with Chloroplast Sequencing

Science Fair Project Idea

Scientific Method

Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Is It a Country Ballad? Listen to the Beat!

Science Fair Project Idea

Scientific Method

Have you ever noticed that hip-hop songs have a fast tempo, while country ballads are usually slow? Do you think there is a correlation between the number of beats per minute (bpm) in a song and the type of music? You can explore whether different genres of music have different bpm ranges by measuring the bpm in several different songs from a number of different genres. Bpm can be measured using free music software, like the one listed below in the Bibliography, or by counting all the beats you… Read more

Is the Spoon Black or Silver?

Blog Post

You will need light-bending science to explain what is going on with this fun visual illusion! Fun with Science: Why does this blackened spoon look silver in water? www.sciencebuddies.org Kids love science that appears to be somehow "like magic" in the way something tricks our mind or eyes into believing something different than what is really happening. When kids are given the opportunity to explore the science behind an illusion firsthand and learn how… Read more
