The document discusses school uniforms and how their impact on student learning could be tested. It also covers different types of mechanical waves, including transverse waves where matter moves perpendicular to energy motion and compressional waves where matter moves parallel to energy motion. Examples are given such as ocean waves, earthquakes, light, and sound.

- 1. Warm-Up, 09.23.2009 Would you be for or against school uniforms? How would you test the truth of the statement “School uniforms cause students to learn more ?” Seriez-vous pour ou contre des uniformes scolaires ?

Cómo usted probaría esta declaración “estudiantes de la causa de los uniformes escolares para aprender más.”
- 2. Notes, Chapter 10 A wave will only travel as long as it has energy to transfer Mechanical Waves: Waves that can only travel through a medium. Kinds of mechanical waves: Transverse waves: matter in a medium moves perpendicular to the motion of energy. Ex: Waves in the ocean Ex: Earthquakes Ex: Visible light Ex: An audience wave Compressional Waves : matter in a medium moves parallel to the motion of energy. Ex: Sound waves Ex: Shock waves (explosions, earthquakes)
- 3. Transverse wave Surfers love transverse waves.
- 5. Compressional Wave Sound moves through air much like this wave.
- 6. Compressional Wave An explosion or earthquake would create this kind of wave.
