Science SCIENCE FAIR PROJECT: Will the number of paddle wheels change how fast the weight is lifted? (Post your document in the next column) || ||
 * Statement of the Problem ||  ||
 * Your question will work. +10 points. **
 * Review of Literature/Bibliography

The weight attached to a waterwheel will raise faster with more paddle wheels.
 * Hypothesis ||  ||

(Post your document in the next column with your saved changes) || ||
 * I'm not really sure what your hypothesis is stating. It should be related to the rate of water flow. **
 * Possibly use this: The faster the water flow, the faster the weight attached to a waterwheel will rise. +10 points. **
 * Variables ||
 * The independent variable, which will be changed and tested is the number of paddle wheels used with the waterwheel. ||
 * The dependent variable will measure the change by how fast the weight is lifted. ||
 * The constant variable for all of the tests is the same rate of water flow. ||

 * Procedure of Investigation ||  ||
 * Materials Used || Aluminum pie plate, 9 inches; available at all grocery stores

Scissors

Permanent marker

Ruler

Drill with 3/8-inch drill bit or other bit size slightly larger than the dowel width; available at hardware stores

Optional (if you don't use a drill): hammer and 5/16-inch width nail; available at hardware stores

Nylon spacer, 3/8-inch inner diameter and 3/8 inch thick. The spacer must fit in the center of the waterwheel. These are available at hardware stores. See Figure 7, below, to see what a nylon spacer looks like.

Epoxy glue; available at hardware stores

Scotch® tape

Wood dowel, 5/16 inch wide and 2 feet long; available at craft stores

Plastic bucket with removable handle, 14 quarts

Cotton string, 30-inch-long piece

Metal nut or other small metal object that string can be tied to

Measuring cup, 2-cup is best

 * Procedure: To set up the experiment || [[file:Waterwheel Procedures 2.pages.zip]] ||
 * Perform the experiment on the first independent variable ||  ||
 * Collect the results for each test by ||  ||
 * Repeat the test more times. Calculate and record the average for the tests ||  ||
 * Repeat the same procedure for the remaining independent variables ||  ||
 * +15 points **
 * Results ||  ||
 * The average results for each independent variable are as follows
 * The average results for each independent variable are as follows. On January 8, 2014, we ran our first trial. The average time with one paddle wheel was 13.16. The average time with two paddle wheels is 17.83 the average time with 3 paddle wheels was 14.53 the average time with 4 paddle wheels was 16.21. On February 6th we started our second trial. The average time with 1 paddle wheel was 13.99. The average time with 2 paddle wheels was 15.64. The average time with 3 paddle wheels was 17.77. The average time with 4 paddle wheels was 21.43.** ||  ||

 * Conclusion ||  ||
 * || **The hypothesis was that the more paddle wheels added, the faster a weight would be lifted. The results showed that as more paddle wheels were added that the times to lift the weight went up. Therefore the hypothesis was not supported.** ||
