The two big weaknesses this problem brought out for many of my students were:<br /><br />1) keeping track of the different units and changing to ocnsistent units, and<br /><br />2) the concept that radius and volume are not directly proportional. Students have a knee jerk reaction to want to say that once they find the radius after 1 day, the radius for 5 days will be five times the first answer. In this way the problem is a great precursor to the related rates problems that will arise in calculus.Kevin Feal-Staubhttp://www.blogger.com/profile/10662814659405934185noreply@blogger.comtag:blogger.com,1999:blog-7007682714488495325.post-22761980835743482332010-05-26T08:18:18.276-07:002010-05-26T08:18:18.276-07:00Has anyone produced the graph in #3 yet?Has anyone produced the graph in #3 yet?Margo Burnshttp://www.blogger.com/profile/12419925951896928297noreply@blogger.com
