CSEF · 2003

Parachutes

Aerodynamics/ Hydrodynamics

Objectives/Goals The objective is to determine if the shape of a parachute's canopy will effect the time it takes to fall to the ground. Methods/Materials Six canopies, with the same surface…

Physics of Flying Fruits

Aerodynamics/ Hydrodynamics

Objectives/Goals Many plants disperse their fruits or seeds (diaspores) by wind; some of the best known are maples and conifers. I studied some of the variables that affect the rate of desce…

Pitch Control: An Analysis of Pitch

Aerodynamics/ Hydrodynamics

Objectives/Goals In this project I will attempt to find the right combination of variables to generate electrical power at low wind speeds without having too much force exerted on the wind t…

Precise Projectiles

Physics & Astronomy

Objectives/Goals The object was to find out how the angle and force of trajectory affect the distance that a projectile travels. Our hypothesis was that the projectile launched with the angl…

Radioactive Absorption

Physics & Astronomy

Objectives/Goals The purpose of this experiment was to test the hypothesis that the effectiveness of radioactive shielding improved with materials of greater density, thickness, and atomic n…

Ready... Aim... Fire!

Aerodynamics/ Hydrodynamics

Objectives/Goals My objective was to determine which mortar design would launch a tennis ball the farthest; a mortar with one baffle or a mortar with two baffles. Methods/Materials Naphtha,…

CSEF · 2003

Rocket Nozzle Efficiency

Aerodynamics/ Hydrodynamics

Objectives/Goals To see how much useful thrust energy for powering model vehicles I could get out of a CO(2) cartridge by varying the size of the nozzle formed by puncturing with a needle. M…

Science Down the Drain

Aerodynamics/ Hydrodynamics

Objectives/Goals The objective of this experiment was to determine which variables affect how fast water flows through a pipe. I believe that many variables including the size of the pipe, t…

CSEF · 2003

Silicon vs. DNA: The Battle Has Begun

Electricity & Electronics

Objectives/Goals Determine if DNA has the ability to solve complex problems which cannot be solved by present day silicon based computers due to technology limitations. Methods/Materials Thi…

CSEF · 2003

Soak Up the Sun

Aerodynamics/ Hydrodynamics

Objectives/Goals In the world we are living in today, there is an enormous need for energy to power our homes, tools, and appliances. The bad thing about this is that it costs money to produ…

CSEF · 2003

Spatter Spatter Everywhere

Aerodynamics/ Hydrodynamics

Objectives/Goals To see when we hit a small amount of blood with an object, if the amount of force will effect the pattern of the resulting bloodstains. Methods/Materials We mixed glycerin,…

CSEF · 2003

Swim Faster! But How?

Aerodynamics/ Hydrodynamics

Objectives/Goals The purpose of this experiment was to find which hand angle in the stroke of freestyle produced the greatest amount of propulsion. Methods/Materials A propeller was built fr…

CSEF · 2003

The Best Hot Water Heater Insulation

Physics & Astronomy

Objectives/Goals The objective of my project was to determine which of four commercially available insulating materials will keep hot water warm the longest. My dad wanted to insulate an old…

CSEF · 2003

The Buoyancy Factor

Physics & Astronomy

Objectives/Goals I created a term called the "buoyancy factor." This means the percentage of what part of an object is submerged under water. (Equation: b-a=c; d-b=e; c/e=%) I tested twelve…
