Part of Lesson Plan: Making Apple Juice

Activity Overview / Details

Take 5 mL of applesauce and put a 800 uL of enzyme into a beaker.  I use pectinase as the example because it is the enzyme with the best results.  Tell students it will have to sit for 5 minutes but for demo you can just model.  Model how to make a juice-o-meter, a graduated cylinder with a funnel on top.  Take filter paper and fold three times to put in the funnel. Make sure filter paper is has one layer on one side, three on the other.  Then place applesauce and enzyme in filter paper and tell students we will let it sit for 30 minutes.  The liquid will drain to the bottom of the juice -o-meter.  Take measurement of liquid in mL.  Tell students they must make three trials.  Show students how to make a data table to take down data on three trials.
