Enzymes As Catalysts for Starch Digestion

The basic concept behind this engaging kit is that all living organisms must alter nutrients in order to make them usable.  Tests are performed in drop quantities using the Lab-Aids Chemplate®.

Kit Includes:

• 30 Droppers, plastic
• 12 Lab-Aids Chemplate® with stir sticks
• 12 Lab-Aids A/B trays
• 6 30-mL drop-controlled bottles of Starch Suspension (shipped empty)
• 6 Bottles of Starch Indicator (Lugol’s) solution
• 3 Lab-Aids 20-mL graduated tubes
• 3 Glucose test tablets
• 1 240-mL supply bottle containing powdered enzyme (amylase)
• 1 240-mL supply bottle containing powdered starch
• 28 Student Worksheet and Guides, Part I and Part II
• 1 Teacher’s Guide
• 1 Safety Data Sheet (SDS) packet

Scientific Concepts:

• Compare the role of an enzyme to that of a reacting substance
• Study the effect of enzyme concentration on rate of reaction
• Observe the effect of time and temperature on enzyme reaction

Classroom Planning:

• Number of students: maximum 24 at the same time
• Number of groups: maximum 12 at the same time
• To complete this kit requires one to two ~50-minute class periods.
