Science Experiment #2: Varying Sounds and Tones (Making Music!)

Our musical glass jar have had a prosperous life making music for well over an hour.  I decided to use some variety to allow us to hear different sounds other than just tones, so we also used a recycled tin can and a plastic container.

The goal was to determine the changes in tone by feeling up each glass jar with 1 cup water, another with 1/2, and then the last two with a 1/4 cup of water.  Then we added 1-2 drops of food coloring to each glass jar.  Harmony did this successfully while supervised. 

The experiment was to determine which glass jar was louder, why, and the differences in the tones that the jars that were filled with different levels of water.  We whipped out our observation booklet and documented the different tones that each one made, compared and contrasted, and determined what the possibilities (the water) were of the tones being so high, low, loud, quite, etc. 

Preschool+ age appropriate and beyond.  Even our Stud had fun banging wooden spoons around..  Simple enough for us and the supplies were easily accessible without purchase.

Happy Saturday!
