Happy FrIday - it's the first lab!

Today students discussed their Mission Impossible Measurement Homework. Scary objects that were measured included knives, guns, tarantulas, and a fist! We discussed how you can use anything to measure and how some things are easier or harder to measure with because of size.

Students watched a Brainpop about accuracy vs. precision and then got set up for a lab. Today's lab entitled the rainbow lab, is a trial run for lab safety and also measures the accuracy and precision of their liquid measurements. Patrisha and Ryan finished first and after discovering the error of using different diameter test tubes, had fairly accurate results.
