Static eletricity

The Laden jar †hat I experimented with use static electricity. The jar made a shock that was an imbalance of electrons. A static charge was created when a rag was rubbed on a record, and the rag was rubbed over the Laden Jar and I heard a crackling .The crackling that I heard was the static electricity balancing out between the record and the Laden jar. †hen l put my thumb on the tinfoil and my index finger on the paper clip that got charged up by the record.

my water wheel

Photo on 3-18-13 at 10.19 AM
In the picture shown above me, R.T., and Ben made the water wheel shown above. The way that this works is it has some holders that scoop the water and it brings it down. It can bring up a big load due to its small size so that it doesn’t take that long to load it up with water.water wheels were first used in 200 A.D. The way the water wheel was used for grinding stuff like, wheat, corn, and other grains. The types of water wheels are known as under shot, breast shot, pitch back, and over shot. under shot is where the water is flowing  in a stream and it pushes the wheel ford and it runs the water wheel. Overshot is where the  water flows over the wheel over the wheel and falls on the wheel turning it. breast shot  is where the water is halfway up the wheel and it falls on to the and it turn there. pitch back is where the water flow from the top but it falls in front of the water wheel. A way that the size helps is because it doesn’t slow it down draining the water and if one blade gets stuck it has a blade above it that will drain water into the other blade that got stuck. Anyway we got 2nd place in the contest for efficiency 🙂 ! I hope you enjoy this post.

wine glass orchestra

I know what you are thinking “What the heck is with the title and the video?” If not you can still read this but it is about hearing not drinking wine and throwing a crazy party O.K.? So to explain, fist off the wine glasses move making the sound and the note of the wine glass. The less water the higher the note of the wine glass. It is actually the resonance of the wine glass and another thing the less the water the louder the note of the wine glass. When it makes the sound it is actually moving the rim of the wine glass. If you hit the wine glass with  the right amount of noise and just the right pitch the wine glass will shatter.

suction cup blades

 So if your wondering what the heck is with that blade here it is. The blade is  in the shape of a suction cup so it can catch more air. We haven’t had a chance to test out the suction cup blades.I came across this idea when I put my handout the window of the car. Then I cupped it. I found that  it was harder to move my hand ford than when it  was flat. I have high hopes for this idea. Hope you enjoyed this post.

Wind Turbine

In science me, R.T.,Toby, and Josh are in a group and making wind turbine. The blades are folded to catch more air.It’s in a triangle-square shape. Picture here  

The voltage is about 1.7 volts. We are thinking about making the blades smaller. We are trying to keep the same blades by making small adjustments. We hope that we can find a way speed the blades up. Our goal is making it go over 3 volts. Hope you enjoyed this post Broy

Robot turtle

In our group we are calling the robot turtle. If you are wondering why we name it robot turtle then I would tell you but I have no idea where  they got that idea. It all started when Max said to the robot “good robot turtle” and then it started. Then everybody started calling it the robot turtle.We are even thinking to change our team name to the robot tootles  to me I think this is starting to go out of hand, then again it is fun to call it robot totole.
