what's a good science fair idea for an 8th grader that has 2 do w/ earth science n hands on experience?

Tell them to bring in working models of "alternate forms of energy".  It might be a little tricky because some of the stuff is flamable.....but I remember having this fair in third grade and it was a great learning experience.  One kid brought in a giant 5 gallon jar half full of pig crap and then showed how it emits gas that could then be used in a combustion engine.  Amazing.  But think...obviously solar...there's got to be the electric type motors....models of combustion engines are going to come in using the corn oil approach etc.

I have got some sites for science projects on volcanoes.\n\nhttp://www.all-science-fair-projects.com/project815_39.html\n\nThis is another project for making a volcano with a purchased kit.\n\nhttp://www.hobbytron.com/make-volcano-model-science-project-experiment.html\n\nThis is another volcano science project.\n\nhttp://www.scienceproject.com/projects/intro/primary/PX001.asp

Go in for help.  My HS science teacher was a bastard until I spent before and after school getting help for physics.  When he saw I wanted to learn and not just be given answers we got along a lot better.  He gave me a great letter of recomendation the next year that helped get me into college.\n\nAlso ask him what his degree was in.  Some HS teachers have a BS/BA in earth science and are teaching chem.  Some are just plain over their head.  Always be polite, and make it known you want to learn.

Are you 15+? Then, you can consider the following:\n\nThis is a project based on Astronomy! Try to simulate our solar and lunar systems around each planet. Bring in the real feel of how plants rotate around sun and how moons rotate around its planets.

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

Chemical reactions are fun how about a baking soda volcano?\nor you can make an experiment showing air pressure and oxygen use, use a big clear jar( mayo peanut butter) a pie plate a bit of modeling clay a candle and some colored water and some pennies.\nplace the clay  in the center of the pie plate\nplace the pennies 2 or 3 high( you may wish to tape them, make 3 or 4 sets set them around the clay so they will support the jar up from the bottom of the pie plate\nplace a birthday candle into the clay  fill the pie plate with enough colored water to cover the edge of the jar and a little more when it is upside down on the pennies\nnow remove the jar, light the candle and replace the jar over it.\nThe candle will go out. this shows that fire needs oxygen and uses the oxygen in the jar.\nIf your jar is not too big you will see the water rise up into the jar. The gas in the jar has changed, it does not have the same pressure it did before the oxygen was removed. The pressure from the outside air makes the water rise. This demonstrates air pressure. Have the teacher light the candle. try it at home a few times you may have to change jar or glass size to get a good effect.\nI do not recommend the electric pickle experiment.

Well I recomend Tornadoes. They made a great project for me ^^ U can actually MAKE a tornado in ur classroom WIHTOUT that dinky water bottle trick! It was a great project. Another good one is Mice and shape rocognition. U put together a maze with portals in the shape of triangles, circles and squares, and see if u can train the mice to recognize that the triangles will always lead to the food instead of what they naturally assume(circles) E-mail me for further details on the Tornado Project which I HIGHLY recomned! happiest_phantom@yahoo.com

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 link to a lot of science fair references.  You probably need to find something that interests you.  If you're not interested in your science fair topic, you won't want to do the research and perform the experiment.  Science fair should be something that you enjoy.  If you enjoy what you're working on, you'll be proud to show it to your classmates and teacher.  \n\nhttp://www.usc.edu/CSSF/Resources/GettingStarted.html

Third grade kids love exploring and finding out about the world.  If you have access to pond water for example,  collect some and have them examine drops of the water under a microscope and then draw what they see.  Have them do it as a real "lab" experiment so that they also write about their observations, label their drawings, etc.  Do a class write up of their observations with each child contributing something to the class write up.  You could continue with a discussion of why we don't drink pond water, etc.  I have used this lesson very successfully with kids from about second grade to eighth grade.  It is one of the most awesome lessons I have used, and with some classes we have carried on activities related to it for days.\n\nTo sdd to what I wrote previously, her eis an answer I wrote for someone who asked for some suggestions on presenting ... some of htis might be basic for you, but some might help ...\n\nMake sure you project your voice, and make your voice interesting and expressive. Speak clearly, and slower than you would if you were just chatting with friends. Don't move around while speaking - try to stand in one spot, which makes it easier for those listening. Don't fidget. Try to use some humor. Use an ice breaker for the beginning of your presentation. One good one is to get everyone to tell something they have done that they think no one else in the room has done. You find out lots of interesting stuff about the group. Start on time and finish on time. Get their attention - don't try to talk over a lot of noise. Find ways to involve them - try to plan some activity that will teach them something and that will fit well in your time frame. Dress in a manner that suits your topic. \n\nGood luck!
