What’s Up with Water? – Sink or Float
What floats and what doesn’t? What if it’s saltwater, or freshwater? Inquiry and imagination lead our “water-ful” scholars today as they set out to answer these questions. Students worked together to come up with rules on floating items in water, then tested their hypotheses using common household items like straws, corks, and bottle caps.
The students quickly began to notice the effect of density, but still had questions. One student asked, “How are boats able to stay afloat if they’re so heavy?” Their observatory skills were put to the test and they stood up to the challenge!
