Quantization of Energy Lab Report Instructions: For this investigative phenomenon, you will need to determine the composition of the new star using a spectrometer. This will help scientists determine the star's approximate age. You will complete Part I and Part II trials of the experiment. Record your observations and test measurements in the lab report below. You will submit your completed report. Title: Quantization of Energy Objective(s): After completing this lesson, you will be able to: explain electron transition between energy levels and explain how emission spectra are a result of electron energy transitions Hypothesis: If each element can be identified by its color, then the color of an unknown star can be use to determined the gas it made up of because specific elements correlate to a color. Procedure: Access the virtual lab and complete Part I and Part II trials of the experiment. Because this lab is virtual, summarize the steps in which data were collected for the samples. In addition, list and explain your controlled variables, independent variable, and dependent variable for this lab. Materials: Known solutions (Barium,Cakcium,Sodium,Rubidium,Potassium,Lithium) Platinum wire(s) Hydrochloric Acid (HCI) Paper Towels Beaker (8) Flame Unknown Solutions (2) Light Source (Hydrogen,Helium,Sodium,Neon,Mercury) Silt Prism Spectrum Variables: Remember, controlled variables are factors that remain the same throughout the experiment. An independent (test) variable changes so that the experimenter can see the effect on other variables. The dependent (outcome) variable will change in response to
