Science - sound
Lesson: Science
Class: Y4 Year: 2018 - 2019
Over the past couple of weeks, Y4 have been carefully learning about how sound is made, how sound travels, how a string telephone works and what the pitch of a sound is.
We carried out a few experiments. We investigated how string telephones work and then how we could change the pitch of a sound using straw trumpets.
Katie Y4 - "It was fun using the string telephones. I found out that the sound travelled better when the string was pulled tight. I think it was because the string was easier to vibrate when it was straight."
Harley W Y4 - "Making the straw trumpets (or Strumpets!) was really funny because every time you cut the straw and made it shorter, the sound got higher and higher."
