This year i did fruit dehydration and I thought it was boring. . Answer: Make an electric motor from a neodymium magnet, dry wall nail and AAA battery. Simple yet no grade… school teacher will be able to explain it, parents will be amazed! You can demonstrate electromotive force and the left hand rule. Link has details.. Answer: The science fair projects I did in high school were: 1. Which is which, Coke or Pepsi? Have several people drink from two cups of cola, with a saltine cracker between. The study is really about perceptions because both cups have Coke. Most folks will say the second is Pepsi because the salt on the cracker makes the second one taste sweeter and Pepsi is a sweeter drink. KEY: Do the test tasting with only one person at a time. 2. Does Handwriting Analysis Provide An Accurate Personality Profile? Have several people write a sample text (I used the poem Mary Had A Little Lamb ) and sign their name. Find a book on handwriting analysis (graphology) and write up a little paragraph about each person from your analysis. Ask the person and their best friend to comment on the accuracy of your profile. If you have siblings in the test group (brothers and sisters), compare their handwriting to see if they look similar but have different profiles. 3. How Many Licks Does It Take To Get To The Tootsie Roll Center Of A Tootsie Pop? Have a lot of people lick one side of a Tootsie Pop and count the licks. I also tracked if the person had a moist/normal/dry mouth and if they pushed hard/normal. Average the number of licks. This is probably enough for the 5th grade level -- ask your teacher for advice. Then I used linear regression on this data to solve the equation: Base # of Licks - Pushing Hard Effect (0 if normal) + Unusually Moist/Dry Mouth Effect (0 if normal) ==== = Actual Licks The math would be too hard for you to do by hand, but you may be able to get someone to help you put the data in a scientific calculator or computer program. It's been more than 20 years, but I think I found something like: Base # Licks = 215 licks Pushing Hard Effect = 75 fewer licks Unusually Moist/Dry Mouth Effect = 50 more licks The key is not to get the same answer I got but to show all the steps how to get the answer you got. By the way, the Tootsie folks are running a Sweepstakes to guess the number of licks -- even if you don't do the experiment (since you're not 13 years old, get your parents to enter the contest).

light bulb circuits like parallel and series circuit
How about: "How do different tempertures affect the vicosity(measure of the resistance of a fluid deformed by shear or extensional stress.whoa)of a liquid". . Good luck! . W…ish me luck on mine,too!
a good ninth grade project could be making a hydraulic lift if it works it will make a great project and u can get good marks
maybe a classic volcano project
Something that you like and that uses the scientific method.
how about......... Is yawning contagious............
I will recommend a project I did with my daughter when she was in grade 5: the assay of Vitamin C in citrus fruit. This is an excellent project because it is of potential us…e, even for scientifically-oriented consumers. It also makes use of easily obtained materials and tools -- all available from Ebay at reasonable cost, from multiple sellers. The total investment should be less than $40 USD, with the equipment and plenty of materials left over for future chemistry projects. The project makes use of crystalline ("metallic") iodine, which is an exceedingly interesting material for the chemistry beginner (or even the adult guide!). A worthwhile detour, while carrying out this project, is to demonstrate the sublimation of iodine, which produces the most beautiful purple smoke! This must be done outside, though, taking care to ensure nobody actually breathes the iodine vapor (which is rather nasty, like chlorine). The project-in-chief is the titration of vitamin c-containing fruit juice(s) (or what have you) with iodine/potassium iodide solution, to produce a color change. By measuring the amount of iodine used with a burette, the amount and concentration of vitamin C in the analysate can be determined with the simplest algebra (within the standard 5th-6th grade curricula, in California public schools). When I did this project with my daughter, we compared unripe citrus with ripe citrus. Can you guess which had more vitamin C? I won't reproduce the instructions for the project here, as these can be found easily on the internet (try googling "ascorbic acid iodine titration") Enjoy!

Do something about erosion.... it woks really well with an earth science fair project... also anything in math will extreamly wow the judges such as the number of __ in a bag …of _____ or, the amount of ___ in and ______ area. i hope this helped!
well, im in the grade 7 and it depends on what kind of projest or chapert ur working on. are u working on cells? bones, ect. if ur working on cells, then you should do a 3d sc…ulpture of a cell. loke using styraphoam. or something. or if ur working on bones, make the entire skelatal system out of modeling clay *NOT PLAY DOAH* just sayin u know?
Leaves Collection. The goal of the project is to explain the concept of biodiversity, and find out how many different species of trees and bushes grow in your backyard (your… street, neighborhood, nearest forest). Next time you go for a walk with kids carefully collect few leaves from each different tree you find in the investigated area. When you back home it's time to do some sorting. Arrange all the leaves on the tabletop. See how different they are! Collected leaves can be sorted in number of different ways: by shape, by size, by http://www.answers.com/topic/leaf . It's also good time to tell children about this differences and why they are important. (We recommend you check the links above before going for a walk ;)) Now you can count how much unique leaves and therefore tree species you have in the backyard. Collected leaves can be turned into herbarium, labeled and used in science fair display or presented to the class. You can go further and find scientific name for each species. Another possible extension of this project is to collect leaves of all kinds of plants in the investigated area. Then you can find how many grassy plants vs trees are there. Model of the Earth - Moon System. This is primer on astronomy. The goal of it is to explain how Moon rotates around the Earth and how moon phases and eclipses are working. For this model you'll need . Straw or bamboo skewers. . Apple . Walnut. . Flashlight. . Little bit of plasticine or Blu-Tack. . Thread You can eat some parts of this model after you're done with the science. First of all you should explain that Earth and Moon is the planet and satellite pair. Moon called satellite because it rotates around the Earth. There is a reason for that - Moon's mass is only 0.0123 of Earth's mass! Compare weight of the apple and the walnut. Walnut is going to be Moon and apple will be Earth. Tie apple to one side of the skewer and walnut to the other side of it. Tie another thread to skewer above the apple. It's good idea to connect walnut to the stick with two threads so that it would not be able to rotate. This is the way our Moon behave - it always turned to Earth with one side. Adjust the connection point so that the whole system would be in equilibrium (see reference picture). Hang it to the ceiling or any other convenient place. --------------------------------------------------------------------------------------------------------------------------------------------------------- When I was in first grade I did does your hart beat faster after you run? I got second place. what you need is a timer or watch, a stethoscope, paper, pencil, any thing to color with, and index cards. I got every 1 in my family and listened 2 their hart beat for 10 sec. then they run in place for 1 min. I repeated the 1st step and then made a double bar graph with help of my mom. next I drew pictures of each individual person running in place and wrote their name above the picture. finally i found a place for every thing on my board. Hope it helped!
For a fourth grader, you can do a standard baking soda/ vinegar volcano or something like using alcohol to show the colors a black marker is made up of. You could also look on… line to try to make a battery out of a fruit or make a small circuit
try to do an experiment on if a frozen seed will grow taller than a regular seed
so that the teacher will know you have been learning in class and not goofing off
There are many different ideas but these are the 3 best and easiest to do. Make a string phone, you can do a egg drop and also there is there is one where you can grow salt cr…ystals .
