Setting Up a Controlled Experiment

Science experiments should be controlled and reproducible. These notions were reinforced as we worked as a class to set up a controlled experiment to answer the question "Does an egg's mass change when it's boiled?" We will actually finish this experiment on Wednesday, since I will be on a field trip with my 7th graders on Tuesday.

Tonight's Homework: None, unless you were absent. Please plan to come to resource on Wednesday if you missed today's class so you will be caught up for Wednesday's lesson.
