Spectroscopy
Lesson
BADoyle
Part 1: Introduction to
Spectroscopy: Spectroscopy Brochure
Objective: Students will
become familiar with basic concepts and
terminology of Spectroscopy. They will research and answer the
guideline questions and Students will present them in a Brochure format.
Audience: High school
chemistry students.
Timeline: Introduction of
lesson in class with one period of computer lab time, allow for
students to explore some basic concepts also review brochure format
with them. Students will be given one week to complete assignment
while basic Spectroscopic ideas are being presented in class
lectures. Student will then be asked to do short five minute
presentations of their brochures.
Grading: Students
will be evaluated on
Did they answer all required
questions effectively?
Did they follow the required format?
Did they include all relevant references?
Classroom presentation.
Peer evaluations for Bonus Points.
Part 1: Students will
answer the following questions:
1. What is spectroscopy?
2. What is the difference between emission and
absorption?
3. How are frequency and wavelength related?
4. What types of energies are involved in
spectroscopy?
5. What equipment is used in spectroscopy?
6. Are there different types of Spectroscopy?
Part 2: For the second
part of the assignment students will choose one of the
types of Spectroscopy and answer the following questions:
1. Give a brief description of the Spectroscopic
method that you choose.
2. Discuss its basic operation.
3. What are its applications to health and/or
industry?

Part
2: Building your own Spectrometer
Objective: Students will
build
their own Spectrometer with a cereal box and a CD and observe spectra
from various light sources.

Audience: High School
General Science or General Chemistry
Timeline: One lab
period, students should be asked to bring in cereal boxes ahead of
class time. Students will build and observe spectra within that
one lab period. For use at the beginning of the Spectroscopy unit
to spark interest in light spectra.
Follow up and grading:
Students will discuss the activity through answering the
following questions.

3: Pogil Activity: Beer's Law
Objective: Students will
explore the concept of Beer's law through a pogil activity from the
Moog website.
Audience:
High School Chemistry students.
