I'm guessing the project needs to be an experiment and not just a demonstration.\n\nWhat area of science are you expected to work in? Are you allowed to use live subjects? \n\nPhysics:\nHow does the length of a string affect the period of a pendulum?\nHow does the density of a material affect the speed of sound?\n\nBiology:\nHow does the color of a light affect the growth of a plant?\nHow does caffeine affect a rat's ability to learn?\n\nAnother thing you might do is Google science projects or go to the library and look for a book.

Do not go for the normal, typical projects that wind up at every science fair--the volcano, the planet mobile, etc.  Just do a project on something you are truly interested in.  Anything can be a science fair project:\n\nDoes expensive lipstick last longer than cheap lipstick?\nDo vegetables last longer on the counter or refrigerated?\nWhich hamburger molds first: McDonald's, Burger King's, or Hardee's?\nDo food packages really contain the amount (weight) of food they list on their packaging?\nCan people tell the difference between namebrand vs. generic shampoo, soda, candy, etc?

My friend Donna has some great science fair links on her page:\n\nhttp://www.lewismiddleschool.com/Earle/earle.htm\n\nAlso - my daughter won her elementary science fair one year with a great project on earthworms.  We got 2 one-gallon glass jars.  We put gravel and dirt in each jar, about half full.  In each jar, we put equal amount of organic garbage - small chicken bone, orange peel, apple core, small piece of newspaper, etc.  In one jar, we put 50 earthworms.  We closed the jars (with airholes) for one week.  Most of the garbage from the worm-jar was gone.  In the other jar, the garbage was still there.  It was a winner!

If there is a "math division" of your science fair, you've got it made, all the`way to state. There are usually few math entries in science fairs, so I feel pretty confident you'll make it at least to Regionals.\nAs a starting point, do a search for the Golden Ratio and/or Golden Rectangle [featured in "The Da Vinci Code"].  \nThis month's Discover Magazine has an article entitled Million Dollar Math and has a few ideas you may want to pursue. Actually the entire mag has some great starting points for science projects. www.DiscoverMagazine.com

Do demonstrations! For volume, for example, you can show a cone has a third the volume of a cylinder with the same radius by pouring water from a cone to the cylinder. Most students guess that the volumes are about the same and it's a demonstration that sticks in their minds. \n\nAnything outside of the classroom is great (if you can do that). Interactive stuff is always good. Get them to estimate the area of the basketball court or other playing surface. Or figure out how many people you could fill your classroom with if they were all lined up lying down.

scavenger hunt\n3 legged race\nbalance a egg on a spoon and run with it for a set distance\nbeanbag toss\nbob for apples\nguess the jellybeans or gumballs in a jar\nrubber duckie pond (just do something on the bottom of some of the ducks so one person or however many you want can win) float them in a small swimming pool.\ntug-a-war (teachers/parents vs. students)\n\nIm sure you could have alot of fun with this day, good luck

i'M IN SIXTH GRADE, AND A GOOD SCIENCE FAIR TOPIC WOULD BE "WHICH SUBSTANCE CONDUCTS ELECTRICITY BEST". iT IS REALLY EASY TO DO AND YOU CAN HAVE LOTS OF GRAPHS. FOR EXAMPLE I HAVE 21 GRAPHS. AND MY WHOLE ENTIRE BOOK IS 93 PAGES LONG. \n\nHOPE i HELP YA!!

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.

Here's a site with alot of different ideas and difficulty levels with instructions.  Maybe you can find something here.\n\nOr you can tell us more about what you are wanting to do and what you like and we might be more helpful on here.\n\nhttp://www.all-science-fair-projects.com/

The following link has some good ideas for different projects. \nhttp://www.all-science-fair-projects.com/category0.html\n\nAlso, the following link might help you set up a science fair display board if you have to have one.\nhttp://www.sciencebuddies.org/mentoring/...\n\nA good elementary science fair project is testing the density of various liquids.  All you need is a tall clear glass or vase and various liquids such as... dishwashing detergent, mineral oil, corn syrup, olive oil, water (dyed blue), molasses, or corn oil.  Use at least five different liquids (of different colors... makes the project more attractive) and slowly pour them into the container.  Also, perform the experiment more than once adding the liquids in different orders and note your results.  This project is easy, but it is also very educational and helps to teach the basic concept of density.
