Temperature and Enzymes

Grades 5-8 Performance Task

Contributed by: Council of Chief State School Officers (CCSSO/SCASS)

Students investigate the affect of adding rennin to milk at different temperatures and measure the time required for the milk to curdle. This exercise presents a scientific test of a simple multivariate problem examining the effects of the enzyme rennin and temperature on the milk curdling process. Students are asked to explain the use of multiple controls in the experiment.
