Format
Time is allowed throughout the workshop to ask and answer questions. We treat video conferences in the same format as traditional science incursions. Please refer to the supporting .pdf document supplied to you on booking which details all of the pre-class, post-class and during class experiment materials your class will use.
1. Program begins with a general introduction and discussion on timezone and weather differences between Australia and your school.
2. We discuss sound as a vibration with your class. Your class participates in the experiment 'coathanger gong'.
3. We run through a number of demonstrations based on vibration in different materials. Students will notice changes in pitch as the shaking objects slow down. Your class participates in the experiment 'balloon and nut hummer'.
4. Discussion of the properties of sound waves. Your class participates in the 'Slinky Shake' experiment.
5. We use an iPad connected to the VC system to demonstrate an oscilloscope. Your students interact with the oscilloscope.
6.Your class participates in creating 'straw flutes' and experiment with them to change their pitch.
7. We demonstrate a sound created from uneven heating.
8. We demonstrate resonance and its implications to building design.
9. Time is made for students to ask further questions and discuss cultural differences between USA and Australia.
Objectives
Your students will:
- learn that sound is created by vibrations.
- understand that sound travels as a wave
- know that sound waves have properties such as amplitude and frequency.
- experiment with the relationship between wavelength and pitch
- learn about resonance
