First graders have been learning all about sound in science! Their studies included identifying and describing sounds, exploring sound vibrations, learning about volume and pitch, and understanding how sounds are used to communicate. Highlights of the unit include: going on a sound walk, exploring sound with instruments, making telephone cups, using the voice memos app to make a sound graph, observing oobleck "dance" on a speaker, and even creating their own instrument. Now... onto light energy!
