Measuring, Error, and Math

Today we started class with a BrainPop cartoon about precision and accuracy and then took the quiz. The quiz was harder than expected, but students did well.

We discussed percent error, a measure of accuracy. Students need to memorize the formula:

your value - accepted value         x 100%
        accepted value

Next we used the whiteboards and learned how to set up conversion problems. Once students felt comfortable, we did a little bit of notes and more practice problems. We will continue to practice dimensional analysis until the students have it down pat. I have plenty of practice problems. :)
