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…

CSEF · 2003

The Magic Flutes

Physics & Astronomy

Objectives/Goals My objective was to understand how the flute works as a musical instrument. Methods/Materials I constructed model flutes from plastic irrigation pipe. My flutes varied in le…

CSEF · 2003

The Photoelectric Effect

Electricity & Electronics

Objectives/Goals This experiment involves solar cells and how they produce electricity. Two important questions are: How is the output power affected by the input power and by distance from…
