# Phosphorus

## Preston High School, Cambridge, Ontario, Canada

Phosphorus: I chose to represent phosphorus as a firework rocket because phosphorus is used to make fireworks. I put a red stripe on the firework to represent one of the two main types of phosphorus; red or white phosphorus. The planet in the top right corner is Venus. This planet is included because phosphorus means "light-bearer" referring to Venus because white phosphorus glows when exposed to oxygen hence the name "light bearer".
