Sound Through Solid Surfaces
We continued to explore sound travel but
this week we investigated sound travel through solid surfaces. Our materials were a wooden board, paper cups
(some with the bottom and others without), and drum sticks. The children used their prior knowledge when
manipulating the materials. They saw the
cups and immediately put it up to their mouth and talked through it as well as
listen through them. They also played
the drum stick on the board. When I
stood on one side and the kids on the other, I asked them what they hear while
hitting the drum stick on the board; some children said they hear a noise
coming from the board others said the noise was coming from the other side of
the room. Either way they knew the sound
was coming from someplace other than where they were. The children understand that sound can move,
we have done many activities in which they have explored this concept. Other children looked around the board to
find the sound. When they realized it
was not coming from their side they looked over the board to find one of the
other children hitting the board with a drum stick. They made the connection between sound travel
and grasped it can move through solids.
