Leif and Dana are the main characters in our mechanical engineering story. Dana quickly discovers a problem...that her fish seem to be pumping their gills hard!
First graders put their knowledge to the test! Why would all the fishes' gills be pumping so hard? We've revealed our first problem of the year!!! How can someone get air into the water so that the fish can breathe easier? Is there a machine that can help us? I WONDER!
