Tuesday 5/21 - Investigation: Slinky Sound Waves

Last updated about 8 hours ago

16 Nsɛmmisa

Procedures

Objective: KWBAT explain how sound waves travel.

Procedure

Working in partners, one of you holds one end of the Slinky and one of you pulls the Slinky across the length of your table.
One of you holds on to one end of the Slinky and stays still. The other student then pushes the Slinky in short bursts toward the student holding the Slinky.
Observe and record how the compressed section of the Slinky behaves when you push it back and forth FORCEFULLY (long, sharp pushes and pulls).
Observe and record how the compressed section of the Slinky behaves when you push it back and forth GENTLY (short, soft pushes and pulls).
Complete the discussion questions below.

Trial 1: Sound Slinky pushed back and forth forcefully

Trial 2: Sound Slinky pushed back and forth GENTLY

A. Soft sounds

B. Loud sounds

Explain your answer for Question 11.

Explain your answer for Question 13.

What happened when the slinky waves reached the partner holding the other end? Explain what you observed by thinking about how a bouncy ball responds when you drop it to the ground.
