Oceanography – Blubber Gloves
Blubber is an adaptation that marine mammals have to survive the frigid ocean temperatures. The young marine scientists used conducted an experiment today to create the most effective blubber possible! Upon first testing the temperature of the water, students found they could hardly hold their fingers in the ice water without protection more than their two layered rubber gloves. The marine scientists then were able to use materials like vegetable shortening, petroleum jelly, and cotton balls inside their “blubber gloves” to model actual blubber.
Ask your student: What was the dependent variable in the experiment today? (amount of time your hand was submerged in the water) What was the independent variable? (the material used to create the “blubber”)
