Scientific Method

This week we've started a new science unit: Measurement. Today we completed our first lab practicing the Scientific Method: making hypotheses, conducting an experiment, recording our results, and coming to conclusions. We completed the "Mystery Powders" lab where we tested the reaction of 6 different powders when water, iodine, and vinegar are added to each powder sample. Below, Ethan uses his pipette to add the liquid to the powder. Ruth and Celia add vinegar to their baking powder and observe that it fizzes and bubbles!
