In another 7th grade science class, they had measured baby rats, and there tails! They were trying to find out the circumfrience of there head, and how much mass the wighed. They had measured the mass for about 2 to 3 days. On there first recording of their mass, they had a total of 4.5 grams. The length of there tail, was about 1cm.
As the time went by, there measurements had increased. I believe that each day the baby rat grew. Maybe some of the rats might not get chubbier, because they don't eat, or they are not getting fed.
