In this engineering science fair project, you will develop and investigate wind turbine rotor designs to evaluate which produces the most energy at a certain wind speed. Nowadays, the need for reliable sources of energy has a lot of people talking about wind power.
Wind power is collected using wind turbines —tall pole structures with a machine at the top that looks like a very large fan. Instead of blowing air, however, turbines catch the air. When the wind blows, it makes the blades of the fan, called rotors, spin around, which moves the turbine on the inside and generates electricity. Basically, the wind does work on the turbine when it how to do eye makeup with glasses it spin.
Work is an application of energy, which makes something move. The energy from the wind's work is taken by the turbine and converted into electricity for use in homes and cities. What is it about the shape of a rotor on a wind turbine that makes it spin easily in the wind? Is it because of the aerodynamics of the rotor—its shape and curvature?
In what is the best sheet count science fair project, you will investigate the hwo of the rotors of a turbine by making a small turbine model and several rotors, varying their shapes and curvatures. You will determine efficiency by measuring energy output using work. The wind turbine model will do work on a small weight by hauling it up from the ground to the top of the turbine.
This will represent the energy output of a wind turbine. You will measure the output of each rotor design by how much weight it can haul—the rotor that hauls the most weight is the most efficient turbime. What are you waiting for? Let's put the wind to work! You should be familiar with the terms below, as well as the names of the parts of the wind turbine. This is a children's how to make a water turbine science project dictionary, priject can be how to get back child support in ohio to look up the terms listed in the Introduction:.

This science fair project is based on the demonstration found on pages of this book. How is this science fair project different from the demonstration turbins in the book?
Figure 1. This is the water bottle tower, cut to hold the smaller water bottle, the nacelle, horizontally. The marbles are used as weight to hold the proejct how to make a water turbine science project place.
Figure 2. The nacelle is mounted horizontally on the tower. In this experiment, you will test different types of rotors on the turbine. You will have two rotors for each scjence instead of three, like on a real turbine, since the latter is far more difficult to make.
Yo will, of course, want to create some basic designs, such as flat how to make a water turbine science project, both rotors curved in the same direction, each rotor curved in opposite directions, etc. Try to come up how to make a water turbine science project some other projext as well, such as rotors cut into a rounded, serrated, or triangular style. See Figure 3 for examples of different rotors designs.
Figure 4. The bottom mke the T-shape will be inserted into the double-straw axle, and the top of the T-shape will be taped to the rotor. In order to demonstrate the efficiency of your rotor designs, the turbine needs an axle, which will spin with the rotor assembly mkae haul wateer weight up the tower.
You already have half of the axle built—the bottom of the scoence of each rotor assembly. Each assembly will be inserted into the nacelle through the hole in the bottle cap, and will connect to another straw, which is inserted into the nacelle through the hole in the other side.

Water wheels have a set of paddles mounted around a central wheel. The falling water is transmitted to another machine by the wheel’s shaft or rotating element. It works like a gear. Water Wheel Project. In this project, you’ll make a replica of a water wheel. Water wheels were used to grind grain, saw wood, and pump water. What You Need. Moving water made the Grand Canyon. That took a lot of energy! In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight. Objective. The goal of this science fair project is to understand hydropower. Apr 14, · 6. After a while, water droplets appear on the inside of the plastic bag. As they get bigger, they will eventually slide down. Glide down like a flow stage that brings water back to the ocean. 7. If the water is still warm or if the bag is left in the window facing the sunlight, it will continue to flow through four different water cycle stages.
Water wheels or waterwheels convert the energy from falling water into power that can be used to do work. Agricultural communities in the past used water wheels to grind grain, saw wood, and pump water.
It works like a gear. To just see the general principal of a water wheel at work with a one time experiment, you can use cardboard and white glue. If you would like your water wheel to last under numerous experiments in the water, go for the more water proof option by using foam board and pins.
Hot glue is waterproof and can be used in place of the pins if making the foam board water wheel. To make the stand for your water wheel, you may consider tracing this pattern. Just click on the link to download and print it. The size of this pattern works best for a water wheel with a 6 inch diameter the size made with a 6 inch long protractor.
Cut out the pattern along the solid black lines, NOT along the dotted lines. Trace two of the legs on the foam board, and two of the support beams. Cut out the water wheel pieces from the foam board or cardboard with scissors or a box cutter. Have an adult help you! Angle the paddles toward the center of the wheel like the spokes of a bicycle. Use glue or pins to attach the short end of the paddles so that they line up on the markings on the wheel.
Attach the other half of the water wheel to the paddles. To make the stand for the water wheel, take one leg and use pins or glue to attach the support beams to the leg at the dotted lines. Take the other leg and attach it to the support beams opposite of the first leg. To increase support for your stand, you can attach the optional base to the bottom of the stand.
Place the water wheel on the stand, with the axle skewer resting in the grooves at the top of the stand. Place your water wheel in the kitchen sink. Open the faucet so that a small amount of water runs out and spins the wheel. Experiment with the placement of the wheel under the stream of water and the amount of water coming out to see what works best.
Watch your water wheel at work by attaching a bucket to the axle. Punch holes into the top of the egg carton section with a skewer so that a piece of string can be looped through to make a handle. Attach a larger piece of string from the handle of the bucket to the axel of the water wheel. Experiment with how much weight can be lifted in the bucket using the power of water.
Water wheels have a set of paddles mounted around a central wheel. Water wheels were used to grind grain, saw wood, and pump water. What You Need: Corrugated cardboard or foam board Flat top push pins, finishing nails, sewing pins or a hot glue gun Pen or pencil Wooden skewer Protractor or six inch diameter round object to trace Scissors or box cutter Ruler String Tiny bucket like an egg carton section used to hold an egg To just see the general principal of a water wheel at work with a one time experiment, you can use cardboard and white glue.
What You Do: Make a straight line two inches from the edge of the foam board, down one short side of the foam board or cardboard. Divide this section into ten 1. These will be your paddles. Using the protractor, trace out two circles on the foam board, marking the center of the circle using your protractor. This is where your axle will connect the two halves of your water wheel.
The axle is the shaft that the wheel rotates on. The support beam is the rectangle. Carefully insert the skewer through the centers of the wheels. Set the water wheel aside. Build a Mousetrap Car.
