Mrs. Reinbold excitedly described today's class, "First and second grade is ready to do some experimenting in music class! After some great questions about how sound works, we’re taking a week to make and test hypotheses about how sound changes in bottles of different sizes, and how the sound will change if we add water to the bottles. Ask your first and second graders what they learned after school tomorrow! (Lots of generous donations made by friends of Mrs. R.)"
