Flame Test Lab
In this first lab of our unit, we recorded the light given off by different metals when burning to determine the identity of an unknown atom. When atoms absorb energy, the electrons jump to a higher energy state and immediately fall back to ground state releasing that energy as light. Since each element has a unique arrangement of electrons, different colors will be emitted by each element. This lab was exciting with the bunsen burner but I was initially pretty confused with using the cobalt glass.

I thought this was a great lab because it was self directed and we could do everything by ourselves. Cool pics by the way!
ReplyDeleteI liked this lab too because we got to see the reactions taking place and plus, the flames looked really cool in general.
