Ninth Grade Physics Science Projects (13 results)

Physics is the study of matter — what is it made of? How does it behave? What laws or equations describe it? From subatomic particles, to the Big Bang, modern physicists study matter at a tremendous range of scales. There's a whole lot of interesting physics at the human scale, too. If physics interests you our wide collection of physics projects is sure to have an experiment that excites you.

You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn about how diffraction patterns are generated, and you'll find out how you can use a laser pointer and a protractor to measure the microscopic spacing of data tracks on a CD.

A siphon is a handy device for emptying out a liquid reservoir that has no drain. For example, they're great for cleaning fish tanks. An interesting aspect of a siphon in action is that the liquid flows "uphill" for a portion of its journey through the tube. This project asks the question, is there a maximum height for that uphill part of the siphon? Read more
