We kept improving our measuring device and tested the Arduino platform timer to check for the systematic linear shift of the speed of sound we had found.
Today, Cabo took his test. I reviewed as much as time would allow before his test. Our brief study session included strategies for if he got stuck on a certain part.
He then took his timed test. He did a great job of properly managing his time, progressing sequentially, and being efficient with his efforts.
Cabo's creativity while approaching challenges like this test is refreshing and engaging.
