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 Lab Report
Objective(s): To determine the relationship between the composition of an unknown
substance and its emission spectrum.
Hypothesis: I think that you can identify an unknown element and composition of
stars by using the color it produces when tested.
Make a prediction for Part I and Part II of this experiment.
For Part I, create an explanation to describe the relationship between the identity of an element
and the color of light it produces when it is heated.
For Part II, create an explanation to describe the relationship between the composition of an
unknown substance and its emission spectrum (line spectrum).
Procedure:
Access the virtual lab and complete Part I and Part II trials of the experiment.
List your controlled variables, independent variable, and dependent variable for each part.
