Lesson
Objectives: 1. Students will be able to explain the concepts
of emission and absorption. 2. Students will be able to identify the
electromagnetic spectrum and its components. 3. Students will be able to discuss three uses
for spectroscopy in the field of astronomy. |
Standards Addressed:
3.4.10 C
• Identify
and analyze the findings of several space instruments in regard to the
extent
and composition of the solar
system
and universe
• Explain
the “red-shift” and Hubble’s use of it to determine stellar distance
and
movement.
3.4.10 D
• Describe
light effects (e.g., Doppler effect, dispersion, absorption, emission
spectra,
polarization, interference).
Lesson Activities:
1. Students will be given a pre-test to determine the amount of background knowledge they have on the subject of Astronomy. We will be using the CPS (classroom performance system: class set of remote controls) to assess knowledge.

2. Students will be grouped in fours to complete a POGIL on the basic concepts in spectroscopy. This was developed for my biology I class in order to bring aspects of physical science into the life science classroom. As such, questions bridging the two disciplines through the process of photosynthesis are included at the end of the POGIL .

3. The students will take
part in an interactive spectroscopy web lesson in which they will
explore these
web pages and complete the interactive questions/activities at the end
of each
section.
Evaluation:
I
will assess the students’ knowledge of the presented
material in three ways.
1. Collection of the pre-test
results
2. I will formatively collect
information of
their understanding as they explore the web pages and will formally
collect the
answers to those questions.
3. Finally, students will be
given a post
–test (same as pre-test) using the CPS
in order to ensure understanding.
