Enzyme kinetics made fun and simple by making it look appetizing and sweet! Included in this slide presentation are suggested laboratory activities and the pedagogy of learning. The target audience is middle school students. This was an assignment in graduate school under the subject Principles and Philosophy of Science Education way back 2006.

• Students in introductory biology classes often have difficulty
understanding many aspects of enzymes.
•Since the physiology of organisms is based on the existence and speed of
chemical reactions, it is essential to understand basics in enzyme
activity in order to understand how life can exist.
•As students discover the importance of enzymes, they are better prepared to
apply their knowledge to real world applications.
•Study of enzymes is a difficult topic for most students because it is an
intangible topic.
BACKGROUND
3. Objectives
To allow students to learn
science through the
process of discovery
To provide a representation
of how one of life’s basic
processes occur
To motivate learners to
make their own discoveries
of knowledge
8. DISCUSSION
QUESTIONS
1. Why did test tube #4 contain only gelatin?
2. What could account for the different results in the tubes?
3. How could the canning process change bromelin?
4. What other fruits contain protein-digesting enzymes?
5. Using fresh pineapple, determine the temperature at
which the enzyme denatures. (for HS and college
students)
6. Design an experiment to find a temperature at which a
meat tenderizer works the best. (for college
students)
9. NOTES
1. We usually do this lab when we are discussing digestive enzymes and
temperature dependence of enzymes. The students like the application of
biochemistry to something they eat.
2. Suggestions:
a. Preparing the gelatin: Stir two envelopes of unflavored gelatin into 800
ml of hot water. This should be enough for three classes. Store it in a warm
water bath when the students are using it so it will pour easily.
b. Remind the students to rinse of the razor blade between types of
pineapple. Clean up is easier if they cut the fruit on paper plates.
c. Canned Pineapple: Use the chunky style.
10. Application of the
Enzyme Kinetics
••All of the three activities comes with quiz questions to be completed after the
experiment. These questions will be used to evaluate the learning
experience for the class.
•The concepts explored will apply to different students at different levels. For
example, the concept of a reaction mechanism is too complex for
elementary or even some high school students to understand. Thus,
quantitative analysis of the kinetics is reserved to the college level.
• The experiment provides a big picture of the framework of the basic concepts
of enzyme kinetics: what enzymes are, how they work, and how
they can be used.
11. The
DISCOVERY APPROACH
The discovery
approach was first
popularized by Jerome
Bruner in a book The
Process of Education
The concept behind the
discovery approach is that the
motivation of pupils is to learn
science will be increased if they
experience the feelings scientists
obtain from "discovering"
scientific knowledge
The idea was supported by the
notion that pupils would learn about
the nature of science, and the
formation of scientific knowledge
through the process of "discovery"
12. In a Discovery Lesson…
