Students built their inventions and tested them today.
Students used a cup phone to investigate the tightness of an object and the pitch it has. We also reviewed what we have learned about light and sound with a kahoot game.
Students continue to focus on sound energy.
Tuesday we looked at how the pitch of the sound changed as we made rubber bands shorter and longer. Today we used a spoon attached to string and cup and learned what sound travels through to reach our ear. Students investigated more about sound. We investigated the thickness of rubber bands and how that affected the sound they made.
