Waves Introduction Take out a piece of notebook paper. 4/1/13
Warmup • What are some examples of waves that you are familiar with? • What is a wave? Pay attention: Today’s paper will be allowed for use on the next open-note quiz.
Procedure: • Materials are at your counter. • Fill a beaker and a dropper pipette with water. • Observe the surface of the water by looking down at an angle into the container. Use the dropper pipette to release a drop of water from a height of about 3 cm above the surface of the water. • Repeat Step 2 with a drop released from each of the following heights: 10, 20, 50, and 70 cm.
Analysis Questions • Using your results, write a sentence that relates how the distance a drop falls affects the wave it produces. • Develop a hypothesis that explains your statement about the drop distance and wave (why does height of the drop affect the wave it produces?).
Transverse/Longitudinal Demo • Using the slinky, we will see two types of waves.
Wave Type Chart • For the top section of Transverse Waves, draw top part of Figure 8 on p. 512 including labels • For the top section of Longitudinal Waves, draw bottom part of Figure 8 on p. 512. • For the top section of SurfaceWaves, draw an abbreviated version of Figure 9 on p. 513.
Wave Type Foldable • For the bottom section of each wave type, write the following: • A definition/description of that wave type • Two examples of that wave type.
Wave Type Chart (old book) • For the top section of Transverse Waves, draw Figure 2 on p. 501 (A, B, C), including labels • For the top section of Longitudinal Waves, draw Figure 3 on p. 502. • For the top section of SurfaceWaves, draw Figure 4 on p. 503.
Extra Questions • What are the properties or characteristics of a wave (what makes something a wave)? • How are waves related to energy and matter?
