Antler Scoring

In this presentation, students measure antlers as biologists do. They'll measure the number and length of the points on each antler, the length of the main beam, and the circumference of the main beam between each point. Students will work in groups to take careful measurements of antlers (using fractions), calculating the totals, and comparing different antlers.
 
Students will need to know how to add fractions and mixed numerals which includes changing to a common denominator. Students need to bring pencils to this presentation. This presentation needs to be held in a room (library, science room) with extra space available so students can work in groups around tables.
 
Scientists take their measurements from a particular group of animals and use the figures to compare the health of a herd over a period of time. For example, if antler length changes dramatically between the sixth and seventh years of a study, the scientist might investigate further to see what has affected these animals. Biologists are also studying antlers in the hopes of learning the secrets of rampant cell growth, secrets that may unlock cures to various forms of cancer. See attachment Antlers provide clues about animals.

Students must be proficient in adding 8 different mixed fractions with a common denominator.  Grade 7 and 8 classes only.
