Today we learned how sound is a vibration! Your child made a paper cup telephone to experiment with how sound vibrations travel.
Something that your child might have found surprising is how well sound can travel through string, as long as the string is taut. You can support your child’s curiosity by inviting them to consider whether sound can travel through any material. For example, here’s a fun, easy experiment you can do at home: Will sound travel through the wall? Have them try holding a cup to their ear, just like with a paper cup telephone, but with the bottom of the cup pressed against a wall. Then go to the other side of the wall and talk. See if it works!
What we're learning in first grade. Students are also making comments in class! At home add to the posts, too.
