Lab Safety
My Partner and I were doing our lab and a beaker fell on the floor. The bell rang right after that so we left it on the floor. Safe or Not Safe

1st step in the Scientific Method
Question/Observation
Variable that you change in an experiment
Independent variable
1st step in engineering design process
Define the problem with criteria and contraints
Before our group started our experiment, I made sure that my hair was pulled back and my sleeves were rolled up. Safe or Not Safe
What is Safe?
Descriptions using numbers
