Introduction

Top of Page

The purpose of this lesson is to assist students in identifying and applying the basic concepts of light and sound waves.  At the completion of this lesson, students should have an understanding of the basic properties of light and sound waves, including how waves behave as well as how to apply these concepts to solve practical problems.

This lesson was developed to support the Montgomery County Public Schools' 7th grade Science "Light and Sound" Unit.   The lesson involves some language arts connections.  

Before beginning this lesson students will need to be familiar with the use of internet sources for research purposes.

Maryland Learning Outcomes Addressed:  SCIENCE 
5.7.14 Describe behaviors (i.e. reflection, refraction, and absorption) and properties (i.e. wavelength, frequency, amplitude, and velocity) of different types of waves. 
5.7.17 Explain that white light is a mixture of many different colors and that colored light is a mixture of some of these colors.
5.7.18 Explain how the interaction of white light with an object produces the perceived color of the object.

TEACHER TIPS:
Step 1: Assigning Roles
The "Audio Engineer" role is the most complex in terms of the problem to solved and the application of scientific concepts. This role might be designated for higher ability level students. 
The roles of Lighting Specialist and Color Technician are of approximate equal difficulty.

Steps 2 and 3- Research
It is optimal that each student be assigned his/her own computer in the lab for research.  If this is not possible, have students pair-up with another student who has been assigned the same role in order to share computer resources.  
You can either have print copies of the "Printable Background Questions" for students to write on or have students save their own copy of the "Printable Background Questions" and type their responses to these questions directly on the computer. 
Continually remind students to record bibliographical information for each site they visit.   

Step 4: Discussion Groups
Encourage collaboration among students by building in time for students with the same roles to meet to discuss possible solutions to the problems. 

Step 5: Writing the Plan
Encourage students to use their peers as editors of their written plans before final submission.

Each group's final plan will be assessed using the  Grading Rubric provided.  A discussion of the contents of this rubric should take place at the beginning of the project so that students are aware of the expectations for their final plans.

Conclusion

Top of Page

At the completion of this lesson, students will have gained a great deal of knowledge about how light and sound waves behave, as well as some real world applications of these concepts.  Students will have an understanding of how reflection and refraction of waves can cause the waves to be redirected.  They will also understand how we see certain colors and how to mix colored light to produce white light.  The value of using real world problems to learn these concepts will make them much more memorable for students.
