To illustrate how polar bears stay warm in the icy waters of the Arctic, we do the classic blubber experiment. This year one of my goals for myself is to make my science curriculum more inquiry based. So, I came up with this "scientific recording sheet" for my students. I like it make it sound official. :) I used a similar one for a few experiments that I did earlier in the year and it worked well. I'm trying to get the kids used to using the scientific process, even if the end result of the experiment may seem obvious.
