Day 61: Fireworks!
By Mr. G on Nov 14, 2007 in Chemistry, Featured
By demonstrating the flame tests of six common elements (Calcium, sodium, barium, copper, strontium, and potassium) we were able to observe the color that is characteristic of each element (Red/orange, orange/yellow, yellow/green, green, deep red, 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. Image source
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!
