Tips for Teachers
The following Tips for Teachers were generated to better serve
the Elementary teacher s of the Vancouver School District.
If you have any of your own Tips, please send them to me (Kris
Skrutvold at the following email address: kskrutvo@vansd.org)
and I will post them on the Kit Resources web-site. (Currently
being developed)
Kit Needs and Concerns
Wooden meter sticks needed
Strobe light needed
Make all the nails out of the same compound
Slinky needed to simulate sound waves
Kit Modifications
Lesson 1: Thinking about Sound
Lesson 2: How sound travels
Introduce sound waves via strobe light to show frequency
vibration of sound
Use a slinky to demonstrate sound waves
Lesson 3: Making sound with nails
Lesson 4: Making sound with rulers
Put all the nails on foam and strike with a pencil
Move the lessons around so that rulers are before nails--easier
to
explain when the nails don't perform correctly
Lesson 5: Exploring Pitch
Xylophone to test different sound frequencies and resonance
Send home directions for a simple xylophone
Lesson 6: Vibrations we can't see
Compare water waves with sound waves
Challenge: do you hear underwater?
Lesson 7: Designing a reed instrument
Have students bring in musical instruments
Lesson 8: Making a model eardrum
Use rubber stretched over cups instead of noise makers and
have
the students hum
Lesson 9: Making sounds with string
Lesson 10: Changing pitch by changing tension
Lesson 11: Tuning a stringed instrument
Lesson 12: How do different strings sound?
Lesson 13: Making louder sounds with strings
Lesson 14: Making sounds with air & strings: The human
vocal cords
Lesson 15: What have we learned about sound?
Lesson 16: Sharing what we have learned about sound
Mini speaker
Styrofoam cups were wrapped with copper wire 20 times. A
magnet was placed inside the wire ring. The wire was attached
to a speaker
