Gear Systems in Fourth Grade

Using Gear Generator, and the Carvey, Fourth Grade was able to make wooden gear systems and learned how to calculate rotational ratios.  Plus it was a lot of fun.  Thanks to Lucie deLaBruere for the use of the Carvey!

First Grade Sound Studies

The First Grade has been studying sound as part of our greater Sound and Light unit.  We have investigated how the ear works, and used a plastic cup to model the mechanism of the eardrum.  We then drew how sound enters the ear and is picked up by our brain.  We investigated a variety of sound stations, using drums, guitars, tuning forks, and our own voice - exploring the connection between vibrations and sound.  Lastly, we engineered and tested our own cup phones, maximizing the sound quality and exploring why some design elements were more successful than others.
