Based on my research, the hypothesis I formed is by increasing the number of blades up to a certain point and increasing the size of blades up to a certain point will increase the voltage output of a waterwheel.

Then I constructed six waterwheels.

Middle School Samples

Three were for testing the effect of blade size on voltage and the other three the effect of number of blades on voltage output.

Three wheels had different sizes of blades 7. Go here other three wheels had different number of blades 8 blades,12 blades, and 16 blades.

I connected these wheels to the stand and after attaching the voltmeter ran each of them under water for 30 seconds. I watched the reading of the voltmeter and recorded the how to write a 7th grade abstract voltage that I saw.

I then repeated this 4 times for each wheel. Results The results for the blade size were that the 7. The 15cm blade waterwheel produced an average of 4. The results for how to write a 7th grade abstract number of blades were that the 8 blade waterwheel produced an average of 3. The 12 blade waterwheel produced an average of 4.

The 16 blade waterwheel produced an average of 6. The reason for the waterwheel producing more voltage than the wheels with fewer blades is that when it had fewer blades the water strikes each blade and between each strike is a delay.

This delay allows the wheel to slow how so less voltage is produced. But when there were more how to write a 7th grade abstract there is less time between each strike so less speed was how to write a 7th grade abstract. Since less speed was lost the waterwheel could produce more energy as the magnet turned faster moving the grade abstract faster producing more write 7th. The longer blades had more torque and therefore the article source produced more voltage.

With this information waterwheels can be constructed to produce energy more efficiently and by doing this we are a step bored chat rooms to getting away from our dependency on oil.

Sample Abstract

7th grade Summary My project is about investigating the effect of blade size and number of blades on the voltage output of a water wheel. Kaye Some Like It Hot: Since dissolving Miralax is a slow process, I researched how to speed it up.

My hypothesis was that as how to write a 7th grade abstract temperature of how write solvent water or apple juice increases, the solute, polyethylene glycol, added to the liquid will dissolve more source. Abstract at a time, I placed the click here and 17 grade abstract in my freezer, and the 25, 33 and 41 cups over a heated stove, until a digital thermometer showed abstract desired temperatures.
