I don't know you, your abilities, or your grade.  Consider the following.  Maybe one of them will trigger you to come up with your own original ideas.\n\nTry building a homemade solar oven:\nhttp://www.everything-candles.com/homemade-solar-oven.html\n\nOr plan an energy efficient community.  Use your imagination.  How many people will live there?  How will the houses be constructed?  How will the roads be maintained?  How will the schools be heated?  What fuels will you use?  Types of energy?  Etc.\n\nWhich types of alternative energy would work well where you live?  Wind?  Solar?  Hydro?  Do some experiments and some research of local landforms and resources to see what type of energy could best be harnessed in your area.

If u want something easy u can make a rpleca of the solar system. U can by those foam balls and spray paint them. Or u could do an experiment on two plants giving one sunlight and no light to the other. But still feed and water them.

I don't know what your interests are, but one experiment that I have done in the past is building an electric motor.  It's easy and does not require a lot of equipment.  I'll include the equipment list below.  If you are interested, send me an email and I will send you a picture of the setup.  That would be easier than explaining it here.\nEquipment required:\n1)Small stable platform, like a wooden board (maybe like 6 inches long and 4 inches wide, and perhaps like 1/2 inch thick).  Maybe a piece of cardboard would work as well.\n2)Magnet (something like 1 inch by 1 inch and 1/2 inch thick)\n3)Copper wire with a small diameter (something you would be able to wrap around your fingers)\n4)6-Volt battery (might be called a lantern battery). The shape of the battery is rectangular and the battery terminals look like little springs at the top of the battery.\n5)Two paper clips\n6)Two thumb tacks

I would suggest the rock cycle. This is a basic earth science project that you can make as simple or complex as you want. You can identify the three major parts and how they interact going from one part of the cycle to another. You can identify the different properties of these rocks (and find samples if you want). If you want to make it really elaborate, you can bring in how plate tectonics drives the rock cycle, and how volcanism, metamorphism, and sedimentation form the Earth's surfaces.\n\nAnother topic that might be interesting to you would be to identify all the products and materials around you that come from rocks and minerals. Since this includes almost everything (e.g gypsum wallboard, clay in ceramics, iron in cars, aluminum in beverage containers and cars, plastic made from oil, shampoo made from oil, household detergent made from oil, electricity made from burning coal and natural gas, salt on your table, etc). You could look for the most surprising things, and could perhaps include how soil is made from weathered rock so even trees and plants come from rocks. You can do some research on how each of these materials is mined and where it comes from. You get the idea, right? \n\nDepending on where you live, you might do something on natural hazards in your area.If you have earthquakes you could find a fault map for your area and research earthquake hazards. If you have landslides or coastal erosion you could research what causes these things. Of course, if you live next to a volcano that is an excellent topic.  For example, see if you can find an eruption hazard map.  You might want to make sure your teacher approved of this because it might not be within the scope of your class (some teachers might consider this geography more than earth science). \n\nJust a bunch of ideas from a geologist. Hope this helps.

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 some ideas\n\n(1)\nMeasure the hardness and ion content of your local water supply.  You can perform precipitation experiments, measure solid residue after evaporation, and more.\n\n(2)\nSeparate the protein solids and fat from milk.  I think you can do this by adding salt to the milk.  (I've never done it, may be too easy.)\n\n(3)\nDo a project on the danger of confined spaces.  There is a really cool visual experiment that goes along with this.  If you mix vinegar and baking soda in a tall glass you will get a glass full of carbon dioxide.  Since the carbon dioxide is heavier than air, it will stay in the glass for a while (invisibly so).  You can then make a "pouring action" and pour the CO2 into a second glass, although there is no visible flow of gas.  You also need a 3rd glass that has a small, lit candle at the bottom of the glass.  You then make the same pouring action with the second glass into the third and when the CO2 displaces the oxygen and nitrogen in the third glass the candle will get snuffed out.  You can even do this experiment at home for fun!\n\n(4)\nMeasure the pH of common household materials: foods, cleaners, etc.
