A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask.  It is done by using the principles of the kinetic theory of matter.  \nAnother cool project might be doing something with dry ice.  Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions.  Make some dye molecules or something.\n\nHope one of these ideas works for you.

It sounds like you need a multi-meter which is handy for all your electric household needs. You can measure current with most of these and they can be found in hardware stores like Ace in most cases and possible even at places like Wal-Mart. They are not uncommon items. If you want you might be able to go online and search for a amp meter most likely from a physics teacher website. I'm sure your nearest hardware store will carry coil but if not, Radioshack is an option. Problem with Radioshack that I have had is too much money for too little quantity (this is in general and not specific to the coils) if you have time, you can browse the internet for teacher selling sites but you may have to pay for shipping which might also run up the cost. The magnets really depend on what scale you are talking about. Hobby Stores will definitely carry small craft magnets but if you need really strong magnets your best bet is once again a teacher website. I hope that I have been at least some use to you, and best of luck on your experiment/project.

Sorry I'm the kind of teacher you parents despair of because thats the kind of home work I'd set.  My class have to design and make a thermal insulator to stop ice melting this week!!!\n\nTry this link it might help\nhttp://www.volcanolive.com/model.html

(m)\n\nMake a solar cell in your kitchen\n\nWe found this article on http://www.scitoys.com/scitoys/scitoys/echem/echem2.html \n\nIt was super, super, super cool, so we thank them for allowing us to post it at TheSolarPlan.com!  This is nifty!\n\nA solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. \n\nIf we are willing to sacrifice efficiency for the ability to make our own solar cells in the kitchen out of materials from the neighborhood hardware store, we can demonstrate a working solar cell in about an hour. \n \nOur solar cell is made from cuprous oxide instead of silicon. Cuprous oxide is one of the first materials known to display the photoelectric effect, in which light causes electricity to flow in a material. \n\nThinking about how to explain the photoelectric effect is what led Albert Einstein to the Nobel prize for physics, and to the theory of relativity.\n\nMaterials you will need \n\nThe solar cell is made from these materials: \nA sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot. \nTwo alligator clip leads. \nA sensitive micro-ammeter that can read currents between 10 and 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle. \nAn electric stove. My kitchen stove is gas, so I bought a small one-burner electric hotplate for about $25. The little 700 watt burners probably won't work -- mine is 1100 watts, so the burner gets red hot. \nA large clear plastic bottle off of which you can cut the top. I used a 2 liter spring water bottle. A large mouth glass jar will also work. \nTable salt. We will want a couple tablespoons of salt. \nTap water. \nSand paper or a wire brush on an electric drill. \nSheet metal shears for cutting the copper sheet. \n\n\n\n\n\n\nHow to build the solar cell \n\nMy burner looks like this: \n\nThe first step is to cut a piece of the copper sheeting that is about the size of the burner on the stove. Wash your hands so they don't have any grease or oil on them. Then wash the copper sheet with soap or cleanser to get any oil or grease off of it. Use the sandpaper or wire brush to thoroughly clean the copper sheeting, so that any sulphide or other light corrosion is removed. \n\nNext, place the cleaned and dried copper sheet on the burner and turn the burner to its highest setting. \n\nAs the copper starts to heat up, you will see beautiful oxidation patterns begin to form. Oranges, purples, and reds will cover the copper. \n\n\nAs the copper gets hotter, the colors are replaced with a black coating of cupric oxide. This is not the oxide we want, but it will flake off later, showing the reds, oranges, pinks, and purples of the cuprous oxide layer underneath. \n\n\n\nThe last bits of color disappear as the burner starts to glow red. \n\nWhen the burner is glowing red-hot, the sheet of copper will be coated with a black cupric oxide coat. Let it cook for a half an hour, so the black coating will be thick. This is important, since a thick coating will flake off nicely, while a thin coat will stay stuck to the copper. \n\n\nAfter the half hour of cooking, turn off the burner. Leave the hot copper on the burner to cool slowly. If you cool it too quickly, the black oxide will stay stuck to the copper. \n\nAs the copper cools, it shrinks. The black cupric oxide also shrinks. But they shrink at different rates, which makes the black cupric oxide flake off. \n\n\nThe little black flakes pop off the copper with enough force to make them fly a few inches. This means a little more cleaning effort around the stove, but it is fun to watch. \n\n\nWhen the copper has cooled to room temperature (this takes about 20 minutes), most of

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.
