Rat experiment
Fourth grader Hali Carmack is ready to put "Sugar" back into her cage after the rat was weighed and measured. The students kept rat journals, made growth charts, and took care of the rats and their cages - all for a lesson on good nutrition and the importance of calcium in their diets. The laboratory rats and lesson materials were provided by the Dairy & Nutrition Council of Indiana. Comet photo by Jennifer Archibald
