We’ve been learning about longitudinal and transverse waves and now it is time to focus on one type of longitudinal wave: SOUND WAVES.
Today you will receive a CONCEPT MAP on sound (legal paper size) where there are empty spaces in some of the boxes. It will be your job to fill in these spaces correctly after visiting three lesson modules on sound AND the two websites located below. You may work together but PLEASE wear headphones as these modules are VERY noisy!
- Sources of Sound– http://www.engineeringinteract.org/resources/oceanodyssey/flash/concepts/sourcesofsound.htm
- Loundness– http://www.engineeringinteract.org/resources/oceanodyssey/flash/concepts/loudness.htm
- Pitch– http://www.engineeringinteract.org/resources/oceanodyssey/flash/concepts/pitch.htm
These two websites that will also be helpful in filling in the information:
- Sound (from the Worsely School)– http://www.worsleyschool.net/science/files/aboutsound/page.html
- Sound Energy– http://www.worsleyschool.net/science/files/sound/energy.html
