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.
