Day 62: Fireworks! November 15, 2006

Posted by Admin in Chemistry, Homework.

By demonstrating the flame tests of five common elements (Calcium, sodium, barium, copper, and potassium) we were able to observe the color that is characteristic of each element (Red/orange, orange/yellow, yellow/green, green, and purple, respectively). It is different chemical compounds such as these that are used in fireworks to give them their color. We also talked about how and why different elements give different colors before observing the oxidation of Magnesium (bright!) in class.

The Radium Dials projects were due today and most students turned them in on time.

The Fireworks Reading and accompanying Fireworks Response Questions were assigned at the end of class. The response questions are due at the start of class tomorrow!
