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.

go to      www.braingle .com    click on the science link. \nthere is a couple of good one's. (ex) put rubbing alocohol on paper(better than 50%). burn. the paper will not burn due to different burning points.

You can do your own? Thats pretty cool. I always liked the bubble gum mass lab. Take like two whole packages of bubbleyum and record its mass unwrapped (not the weight, your teacher should have a mass scale). Then chew all of it for about forty minutes. Don't swallow. Record the mass of the chewed blob. It'll be less even though its still the same gum. The chewing excretes certain substances out of it (some research required there). This'll actually work for a physical science or a chemistry lab. And while your classmates are working hard on their labs you'll be blowing bubbles the whole time. Hope that helps.

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

Need more info in order to help you...what class level?...what field of chem?...writing project or lab demo?...what is an 'investigatory project'?\nPlease resubmit your question anew with as much info as possible so that we can offer reasonable suggestions...if you simply edit this one we cannot reply twice to same question.

First off.... Find your interests, in order to make the project fun. What interests you? \n\nYou may be a person like me --that doesn't like science, but be creative.\n\nYou could do a topic on disorders:\n\nAsthma,\nAutism Spectrum Disorder- Is Autism genetic?\nADHD -- Is ADHD genetic?\nAnxiety Disorders-- What causes anxiety? \nOr so and so....\n\nThe last science fair project I did was:\n\n"Does music affect your heart rate?" And, of course, the answer was yes. It was a lot of fun-- I hatre science, but I made it fun.. hehe!\n\nHere are some topics:\n\nSexual Reproduction\nFlowers & Plants\nDisorders; Asthma, Autism, ADHD, Bipolar Disorder, Depression, and other disorders.\nElectricity\nAnimals - if you like animals.\nComputers\nFruit\nGardening\nGuns -- how they work, etc.\nFishing\nFarming\nObesity- why is uncommon/common in US and other countries--why is it un/common in other countries? etc.\nExercise-does it affect heart rate? etc.\nDrugs--does it affect a person? If so/if not, what way/s? \nCooking,\nSkin (human skin, how it's formed, etc),\nSleep--scientific--why do teens sleep more/less than adults?,\nSoaps--which soaps work better? And why?\nWhich fertilizer makes plants grow healthier?\nWhat baby products are the best? And why?\nHealthy foods,\nHow does bike riding enhance your muscle strength?,\n\nHere are some of my ideas, as well as this website. Hopefully, it's helpful.\n\nGood luck!\n\nMichelle

Great idea.  What is your hypothesis?  What experiment will you do?  What data will you collect?  How will you interpret it?
