You can compare the picture quality for photos taken at different shutter speeds with the camera handheld vs. with the camera on a tripod. (This is best done with a camera that has manual exposure control.)
There are many types of construction materials used for wood-frame houses. Compare the different uses for and strengths of different building materials, e.g.: particle board,
plywood, pine, oriented strand board (OSB), and drywall (gypsum board, SheetRock). The Science Buddies Materials Science Resource will be helpful for learning about different ways to measure material strength. You should be sure to use the same cross-sectional area of each material in order to make fair comparisons.…
Use a video camera to analyze the angle of lift with different clubs. Measure the distance the ball travels. Be sure to conduct a sufficient number of trials with each club so that your results are consistent. This can also be a great way to work on your swing! (Idea from Goodstein, 1999, 83-85.)
A fractal is, "a rough or fragmented geometric shape that can be subdivided in parts, each of which is (at least approximately) a reduced/size copy of the whole" (Mandelbrot, 1982). There are many different fractal patterns, each with unique properties and typically named after the mathematician who discovered it. A fractal increases in complexity as it is generated through repeated sets of numbers called iterations. There are many interesting projects exploring fractal geometry that go beyond…
What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than…
In the Science Buddies project ,
you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an electric current. The detailed physics of how a changing magnetic field can induce an electric current are described by Faraday's law and Lenz's law
(see the Bibliography for more information about these two laws). For a more advanced version of the Human-Powered Energy project idea, try setting up an experiment to prove or demonstrate these two laws,…
