Unexpected Results Drive Students to Design Their Own Experiment
7th grade students raved about how they did this soda sinking and floating activity last year and in elementary school so they thought they could accurately predict what would happen this year. To their surprise only some sugar content soda cans sank nstead of all the cans. Instantly they tried to find explanations why the sugar soda cans floated and then tried to make the cans that sank try to float but could not. Determining the mass helped them to explain the experiment's results.
