When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.)

For an advanced science fair project, you can build your own telescope and learn how to use it to make observations of the night sky. Can you make your own observations to determine the orbital period of Jupiter's major moons?
The Dobsonian telescope, first built and popularized by astronomer John Dobson, is considered to be the best bang-for-your-buck if you want to build a good amateur telescope. The smaller the telescope's aperture the less expensive to build, but also the less…

What do Nolan Ryan, Mark Wohlers, Armando Benitez, and Roger Clemens have in common? These men are all major league baseball pitchers who have pitched baseballs at 100 miles per hour or greater! What does it take to throw a baseball this fast? Does it come down to having the biggest muscles? Can a ball thrown this fast also be accurate? In this sports science fair project, you will learn about the biomechanics of pitching. Investigate how body position and physics interact to produce fast…

If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults?
In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them!

The Science Buddies project Design Your Own 3D Printed Optical Illusion shows you how to make your own 3D printed "anomalous mirror symmetry" illusions (Figure 1). The illusions are based on the work of Dr. Kokichi Sugihara. You can read his original paper about the illusions in the Bibliography.
Figure 1. Two versions of the "impossible arrow" shape that appears to point to the right while its reflection in the mirror appears to point to the left. Which…

Block off one-third of a soccer net with a cone, 5-gallon bucket or some other suitable object. Shoot into the smaller side from a set distance, but systematically varying the angle to the goal line. Take enough shots at each angle to get a reliable sample. How does success vary with angle? For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to…

What do you consider creepy? Clowns? Zombies? Video game characters with jerky movement? In 1970, a roboticist by the
name of Masahiro Mori suggested that people are "creeped out" by robots that are almost, but not exactly, humanlike.
He called this phenomena the uncanny valley. But researchers are still exploring and defining the uncanny valley.
In this science project, you can do your own exploration—just try not to creep your friends out too badly!

Tilt-A-Whirls, Merry-Go-Rounds, Spinning Tea Cups...does just the thought of them make you dizzy? Why should something so fun make our heads spin so long even after the ride has stopped? Learn about spins, turns, and the mixed signals that fire in our brains when the sensation of dizziness takes over. Weak stomachs, beware. This project has tests that will make your head spin!
