Students in Ms. Senchak’s 8th grade science classes spent the month of September leaning about the Scientific Method. The six ‘steps’ were discussed in detail, with focus on the importance of running a controlled experiment in terms of control/experimental groups, independent/dependent variables and constants. Students analyzed a variety of science scenarios to reinforce terms along with analyzing data tables and drawing conclusions. As a conclusion to the unit of study, students completed a fun Mentos Lab Investigation where each group was given Coke, Diet Coke and Coke Zero to test for the biggest chemical reaction. Students applied knowledge of controlled experiments in order to run the experiment. Three trials of each soda were completed and data was recorded and analyzed. In the end, the overall data showed that Coke Zero is it, producing the best chemical reaction out of all three sodas!
