Double-Slit Interference Patterns

Physics & Astronomy

Objectives/Goals This project was conducted to find out whether the distance between double-slits in a slide would affect the resulting interference fringes the same way with a piece of glas…

CSEF · 2006

Effect of Fins on Water Rocket Stability

Aerodynamics/ Hydrodynamics

Objectives/Goals To see what effects water rocket stability while the rocket is flying. Fins, weight, air pressure, and water-to-air ratio were examined in 3 ways: 1) using a rocket simulato…

Electrical Conductivity of a Candle Flame

Electricity & Electronics

Objectives/Goals The objective of my project was to test the electrical conductivity of a candle flame. Considering the basic structure and physics of a flame, I thought that the center dark…

CSEF · 2006

Electromagnetic Motor Configurations

Electricity & Electronics

Objectives/Goals Electromagnetic motors specifically run on electricity and magnetism. When you put these together they may run very fast. My project#s main purpose is to test the different…

CSEF · 2006

Electrostatics

Electricity & Electronics

Objectives/Goals My project was done to learn about electricity, specifically static electricity, using a charge detector and accumulating charge by combing hair. I hypothesized that the mor…
