Activity:  Sound Wave Lab.

Pre-Activity:  Imagining a remote sensing device that a seal would want invented.

Do Now:  List ten types of waves that you already know something about.

Aim:  To solidify knowledge of a universal concept.

Major Assignment:  To hear wave cancellation and reinforcement using the NAS tools.

Processes, Skills, Goals:  Understanding the basics of observation as the sensing of wave motion, to hear the phenomena of wave interaction, reporting on observations.

Content:  Simple Wave Motion

Instructions:  Explain the key consideration that wave motion is part of a wide variety of common phenomena.  Assess current student knowledge regarding waves, and reinforce basic wave-related definitions.  Narrow down the discussion to focus on wave phenomena, including global heat, phytoplankton, and tide cycle (using the NASA videos).  Demonstrate wave interaction using the National Academy of Science wave lab.  

Materials:  NAS wave lab software, speakers, computer.  Slide show of relevant wave definitions and common applications.  NASA wave motion videos.

Guiding Questions:  What do you already know about waves?  Cycles?  What types of wave phenomena are there?  Does every wave in the ocean push a boat to the shore?  So does the water move forward?  What moves? (Energy).  What do you know about sound waves?  How are highs and lows of sound created?  Transmitted?  Altered?  Heard?  Felt?  What makes sound seem loud or soft?  How can understanding waves alter your life through career, economic, and personal decisions?

Homework:   Complete lab questions.
