My students wanted to know why such massive, beautiful creatures were endangered. To explain this, they needed to understand a bit about global warming and how the sea ice is melting. To do this, we read a few books on polar bears. Our favorite was this one:
We also watched a few parts of these videos:
My class’ favorite video was this one:
After learning about the sea ice melting, we completed an easy experiment to show my students how ice melts.
For this experiment I froze water in our class set of test tubes and then had my students pour salt on top of the ice. Then they added drops of colored water to the top and watched how the ice cracked and melted.
Within moments the cracks started and my students began discussing the impact the salt was having on the ice. We discussed how the salt was making the temperature of the ice rise and was causing it to melt. We talked about how this is kind of what is happening with global warming.
My students asked to use our lightbulbs to watch the effects better. This was a great addition to the experiment!
In addition to all of the fun science activities we completed during this study, we also created the most beautiful paintings of the Northern Lights. Click on to read how to create stunning paintings of the Northern Lights!
