where can i find a middle school science experiment on light?

Boy, you are really time-constrained!  What kind of light?  Edison did an experiment on sending sound over light waves, but was limited to visual light, in air (not laser light, in fiber optics like we use today.)  What equipment have you?\nSuggestions, without knowing much:  Send a beam of light as Morse Code and determine the maximum distances based on different times of day, weather conditions, strength of light beam, type of light beam, acuteness of receiver's eyes.  \n\nOr better yet if you are a computer geek  :), do it with a photo cell as the receiver and send the signal to a computer for analysis and conversion into text.\n\nGood Luck!  Let me know your results!

If you go onto "google.com" or "yahoo.com" and do a search on "5th grade Science Fair Projects", you will get many ideas.  Just pick the one you find most interesting.

Hi!  This has been my fav. site when it came to doing science projects so far.  http://www.stevespanglerscience.com/index.php\nRemember to call your local papers and have a write up done on it so you have a good turn out for the crowd.  Good luck!

All of these seem to have good starts for ideas.  You should be able to find plenty of good projects that you'll be able to work on prior to your science fair,\n\nhttp://yahooligans.yahoo.com/Science_and_Nature/Experiments_and_Activities/Science_Fairs/\nhttp://www.ipl.org/div/kidspace/projectguide/\nhttp://school.discovery.com/sciencefaircentral/\nhttp://www.scifair.org/\nhttp://www.cdli.ca/sciencefairs/\nhttp://www.isd77.k12.mn.us/resources/cf/ideas.html\nhttp://staff.washington.edu/chudler/fair.html\n\nGood Luck

its best if the child find something interesting to them. go to the library and ask the librarian for info on science fair experiments.\n\ngo to the science teacher for periodical, then pick an experiment.

The best project will be one that has some interest to the 8th grader. So my granddaughter likes animals. But my youngest boy likes photography. So a pinhole camera would bore my granddaughter but would have caught the interest of my son.\n\nThat being said... Here's an easy one. Go to a store and find some cheap analog clocks (clocks with hands) that run on a single AA battery. Then go to Radio Shack and get some battery holders and some "aligator clip leads" -- short wires with clips on either side. And get a bunch of different brand batteries of different sizes (if you are trying to get by simply, use only AA batteries and then you just need the clocks and the batteries).\n\nTake off the battery covers and hook up the battery holders to the clocks with the clipleads (unless you are only using AA batteries). Then put batteries in and see how long it takes for the clocks to run down. This may take a long time. If you are short on time, try this. Get a flashlight bulb at radio shack and put it across the battery with the clock. So this way the battery is running the clock and the flashlight bulb at the same time. Note the time on the the clock and check it every day to see when the clock stops. You can graph the results easily.\n\nQuestions (form a hypothesis and answer one or more of these):\nWhat lasts longer, a AA, a C, or a D battery?\nWhat brand of battery lasts longer?\nWhat lasts longer, a standard carbon-zinc battery or an alkaline battery? What is the cost difference per unit? Per run time?\n\nA little research on the internet about how batteries are built, and the different technologies (carbon-zinc, alkaline, nicad, NiMh, lithium, lead-acid) and you have a great project.

Optical Spectrum Analyzer (OSA) is probably what you're looking for...nice for discovering chemical composition of light source and probably a zillion other different things.

Try eduplace.com or edhelper.com\nCrayola.com is also free and has great ideas.\nThe public library has LOTS of books for crafts and BillNye type experiments.  The books by VANCLEAVE are excellent and easy to follow and implement.\nBelieve it or not, google exactly what you want, you'll find lesson plans too!
