5.06 Electromagnetic Spectrum Lab Report
Instructions: In this virtual lab, you will use a virtual spectrometer to analyze astronomical bodies in space. Record your hypothesis and spectrometric results in the lab report below. You will submit your
completed report to your instructor.
Name and Title:
Include your name, the instructor's name, the date, and the name of the lab.
Title of Lab
Electromagnetic Spectrum Lab
Student Name

MISSION OBJECTIVE: Objectives(s):
Scientists can analyze spectrometric patterns to determine which elements are present within objects in space. Your mission is to analyze the absorption patterns produced by newly discovered moons and planets.
MISSION PREP:
Identifying Absorption Spectrums
Practice Problems: Review the unknown spectrums presented in the virtual lab. Match it with one of the six known spectrums provided in the virtual activity.
Unknown Spectrum One
Hydrogen
Unknown Spectrum Two
Helium
Unknown Spectrum Three
Lithium
Unknown Spectrum Four
Sodium
Unknown Spectrum Five
Carbon
Unknown Spectrum Six
Nitogen
MISSION GO!
Hypothesis:
In this section, please include the predictions you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
Moon One contains the elements Lithium
and Carbon
. Moon Two contains the elements Sodium
and Nitrogen
.
Planet One contains the elements Hydrogen
and Carbon
.
Planet Two contains the elements Helium
and Carbon
.
Data:
Record the elements present in each unknown astronomical object. Be sure to indicate “yes” or “no” for each element.

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.
1.
Using two to three sentences, summarize what you investigated and observed in this lab.
I observed 2 different spectrums put together make different absorption results. I had to look at the results and put together which 2 spectrums made up that result.
2.
What are the independent variable/s (what you control) and dependent variable/s (what changes because of the independent variable) of your activity?
Independent Variable:
The astronomical object viewed by the spectrometer is the independent variable.
Dependent Variable:
The spectrum of each astronomical object is the dependent variable.

Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?
There are many different types of bodies (stars, galaxies, planets, etc.) that emit radiation of different frequencies. To study these correctly scientists need different types of equipment. 4.
If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.)
what would make them similar to Earth would be oxygen
5.
We know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. How does it help us find out the make-up of stars? The electromagnetic spectrum helps us find out what makeup of stars by looking at specific wavelengths of light emitted or absorbed by elements in the stars' atmospheres,
enabling astronomers to identify the chemical elements
6.
Why might it be useful to determine the elements that a planet or moon is made up of?
elements that a planet or moon is made up of is useful for understanding its Earthly
andevolutionary history
