Rainbow Lab

Today students began class by practicing percent error math problems (Box L on the homework sheet). They watched a BrainPop on scientific notation and took the quiz while a few students took, or re-took, the safety test. All Friday test-takers passed their safety tests.

The rest of class was spent on the first lab on accuracy and precision. Students worked with glassware and colored solutions. I watched them to see their maturity, safety, and ability to follow directions. If the lab is done correctly, precisely, and accurately, students get a row of test tubes with rainbow colors and they should all have the exact same amount of liquid.
