Science Fair Project Idea
As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move! This experiment will investigate the stimulus/response relationship in plants and prove that plants can move up and down in response to gravity. Read more

Science Fair Project Idea
thumbnail This science project presents an interesting puzzle. A disk of wood will float face-up; that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats on its side with the circular cross-section perpendicular to the surface of the water. If you think about it, disks and logs are both cylinders. Is there some intermediate length of cylinder that floats with the circular cross-section at a tilted angle? Try this experiment to find out! Read more

Science Fair Project Idea
Farmers face a variety of challenges in their efforts to grow crops. One of the chief challenges is the presence of unwanted plants (weeds) that compete with the crop plants for water, nutrients, and light. If the weeds are not suppressed, they can reduce or completely eliminate the amount of food derived from the crop at harvest. In this biotechnology and plant science fair project, you will simulate the competition between crop plants and weeds, and determine whether the use of an herbicide,… Read more

thumbnail 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.

Science Fair Project Idea
Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one important variable among many that determine the ideal conditions for seed germination.

Science Fair Project Idea
thumbnail Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many naturally occurring molecules have this property, called chirality. Chiral molecules can interact with polarized light in an interesting way—they rotate the plane of polarization. This chemistry science fair project describes how to make a homemade polarimeter… Read more

Time Required Average (6-10 days)
Prerequisites This is a "do-it-yourself" kind of science fair project. It may present challenges that will require some technical creativity. Some experience working with digital pictures and videos on a computer will be useful.
Material Availability To do this science fair project, you should already have the following materials and equipment: a laptop computer or other device with a flat-panel screen and a digital camera that takes short videos.
Cost Low ($20 - $50)
Safety Use caution when working with glass panes, as they can cut if they are broken.
Science Fair Project Idea
thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more
