Our next steps...to imagine various solution to our oil spill clean up. There's a catch, however. Real oil spill clean up processes cost millions of dollars. So besides a materials constraint for this problem, fourth graders will be given a cost constraint as well. With only $20 million to spend, they are quickly seeing how they need to choose their materials wisely in order to get the best results. Think $20 is a lot? Well every time they use a cotton ball, Mrs. Brinza will be charging them $2 million, so the money will go fast! Check out some of their imagined solutions below!
With the results of their controlled experiment finalized, fourth graders had a chance to really analyze which materials were best at either absorbing or containing oil.
