Rocketology

Objectives/Goals To determine the correct ratio of baking soda to vinegar that will result in the highest launch of a plastic canister Methods/Materials Material : 1. Plastic Fuji film canisters with the tops (at least 3). 2. Construction paper, any color, 9 inches (in.) X 12 in. (1 pack). 3. Sotch tape (1 roll). 4. Scissors. 5. Permanent marker. 6. Ruler, in inches. 7. Optional: Ladder. 8. Baking soda (1 box). 9. White vinegar (1/2 gallon bottle or jug). 10. Measuring spoon, 1/8 teaspoon (tsp.). 11. Measuring spoon, 1 tsp. 12. Bowl. 13. Water. 14. Spoon. 15. Safety goggles. 16. Adult volunteer. 17. Lab notebook. Methods : 1. We collected all over materials and put it on the Table. 2. We read the instruction for the experiment and made one change. The change was that we did not put construction paper onto the film canister as the canister was heavy and was not lifting up too much anyway. 3. We made a measur

The Green Machine

Objectives/Goals The objective of my project was to determine the effect of altering the mass and aerodynamics of a vehicle (rocket) on its fuel efficiency. Methods/Materials A pressurized, water powered, bottle rocket was chosen as the vehicle to remove the variables of ground friction and driver's style. After designing the optimal test rocket and establishing the controlled variables--namely the amount of fuel (propellant) and engine thrust (air pressure)--through testing, experiments were conducted to determine the effect of varying amounts of mass and different aerodynamics on the relative fuel efficiency of the rocket as measured by the altitude achieved during each test flight. The effect of mass on fuel efficiency was determined by placing varying amounts of cargo in the test rocket and calculating the altitude that each flight reached. The effect of aerodynamics on fuel efficiency was determined by placing nose cones of varying angles on the test rocket a

What A Drag!

Objectives/Goals Can a functional wind tunnel be constructed that allows the aerodynamic testing of automotive models? Will this testing match known aerodynamic values for modern vehicles? Can a model be constructed that is aerodynamically superior? What design features would this model incorporate? Methods/Materials Construct wind tunnel using plans from the internet. Build five model cars out of styrofoam blocks. Test each car ten times to determine aerodynamic force measured in ounces on a postal scale. Compare these values to known aerodynamic coefficients. Use derived information to begin independent testing of aerodynamic features. Cut and shape styrofoam blocks in pursuit of aerodynamically superior body shape. Analyze the effects of various features. Results The aerodynamic forces measured were similar to the results I hypothesized. The cars in order of least force to greatest drag force were: EV1, Toyota 2000GT, Porsche 911, Chevrolet Z28, and Hummer H2.

Unleash the Power of the Pinwheel

Objectives/Goals The objective is to determine if the orientation to the wind affects the amount of power generated by a wind turbine. Methods/Materials A wind turbine was constructed using an empty oatmeal canister weighted with heavy bolts to keep it grounded, a wooden skewer, a homemade rotor, two feet of thread, one end secured to the aft shaft and the other to five #1 size paper clips. Using a hair drier, wind was directed toward the rotor at the following angles; 0 deg., 45 deg., 90 deg., 135 deg., and 180 deg. The time to raise the load of paper clips to the base of the shaft was calculated in seconds, using a stopwatch, and the distance the paper clips were raised at each position was measured in inches, using a tape measure, but then converted into meters. After conducting three trials, times and distances were averaged to determine which orientaion to the wind source created the most power. Results After testing all five angles three times, I#ve found

Factors That Affect a Hovercraft's Speed

Objectives/Goals The objective of this project is to learn about how a hovercraft works, determine the factors that affect performance, and improve design. This project studies a number of forces acting on a homemade hovercraft such as weight, gravity, friction, and lift. Methods/Materials The 4-foot (1.22 m) diameter hovercraft was constructed out of a 3/8 inch (9.5 mm) plywood platform and a skirt made from visqueen plastic sheeting. A leaf blower was used to provide lift and duct tape was used to prevent air to escape at interface of the platform with the skirt and engine. A surface test, skirt test, weight test were performed. The surface test analyzed concrete, artificial turf, and natural grass. The skirt test analyzed a six-foot (1.83 m) and a seven-foot (2.13 m) skirt. The weight test examined three different payloads, 39.91 kg, 28.57 kg and 0 kg. The engine test was conducted using three different engine settings with varying flow rates/air velocities. Re

Swimming Can Be a Drag

Objectives/Goals To determine the effect surface condition (the suit) and different forms or body strokes (good form, bad stroke and streamlining) can have in relation to the speed of a swimmer. Methods/Materials Make wooden scale models of myself of 3 different swim forms or strokes. Use pennies to match density of a human body. Construct a swim tunnel using 8" pvc pipe. Attach a scale to measure drag force. Determine water speed. Conduct tests at different flow rates, measure the force on a scale, measure height of water in pipe, and calculate water speed. I conducted 108 trials. Results The experiment went well. The drag on the swimmer as related to form showed that at higher speeds, good form is important. For my size, the results indicated that a drag force of 2-6 pounds can be expected at my swimming speeds. My research indicated that swimming is only 9% efficient. So you have to apply 11 times more force to overcome the drag. Streamlining is more effic

Which Wind Turbine Blade Design Will Produce the Most Power?

Objectives/Goals The objective of my project is to determine the best aerodynamic blade design of a wind turbine that would produce the most power. I hypothesized that the feather shaped design (Design No. 4) would produce the most power (milliwatts). Methods/Materials Seven sets of three blades each were constructed by making a proof set and making duplicates of the blade. The blades were constructed of Model Magic because of its lightweight, fast drying, and non-cracking properties. These blades were then mounted on a wind turbine. The wind for the experiment was produced by a 45 centimeter diameter fan with the turbine 90 centimeters away. The voltage and amperage was collected at 100 samples per second for 60 second runs. The wattage was then calculated. This procedure was repeated for ten trials for the seven sets of blade designs. Results The average wattage produced for: Design No. 1 was 12451.86 milliwatts, Design No. 2 was 1756.21 milliwatts, Design No. 3
