Exploring Wave Types: Hands-On Investigation and Understanding

In this interactive lab session, students will delve into the nature of waves through observation and experimentation. Participants will fill containers with water and practice dropping water from various heights to analyze how drop distance influences wave production. They will explore both transverse and longitudinal waves using a slinky and will summarize their findings in charts and foldables. By the end of the exercise, students will develop a deeper understanding of wave properties and their relationship to energy and matter, laying the groundwork for future scientific exploration.

Presentation Transcript

  1. Waves Introduction Take out a piece of notebook paper. 4/1/13

  2. 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.

  3. Copy this Data Table

  4. 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.

  5. 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?).

  6. Wave Type Chart (Draw this on the back of your Lab paper)

  7. Transverse/Longitudinal Demo • Using the slinky, we will see two types of waves.

  8. 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.

  9. 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.

  10. 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.

  11. Extra Questions • What are the properties or characteristics of a wave (what makes something a wave)? • How are waves related to energy and matter?
