PRODUCT DESCRIPTION

One of my favorite Biology labs ever, this enzyme lab comes with the student lab handout, a teacher’s guide, and a post-lab quiz. This hands-on activity was designed for the biochemistry (organic chemistry) chapter in a high school Biology class, but it could be used in a middle school Life Science course as well. Take a look at the preview to see if it’s right for your students.

These key terms and concepts are covered:
• enzymes
• substrates
• catalysts
• organic compounds
• polysaccharides
• proteins
• reaction rates
• denaturation

This is a FUN one! It’s safe, we always get great results and students get to use a variety of lab equipment, such as:
• balance
• beakers
• funnels
• graduated cylinders
• pipettes
• stirring rods
• stopwatch or timer

And, they get to practice these lab procedures:
• measuring mass
• measuring volume
• timing an experiment
• recording data
• graphing results
• performing calculations

And, if you use the included Extension Ideas, students will:
• design and carry out their own experiment
• write a formal lab report

This product is the perfect complement to my other Biochemistry products:

Molecules of Life PowerPoint and Notes

Molecules of Life Task Cards

Biochemistry Review Qubes

Each lab from Science Island follows an outline that will help students answer the problem in a systematic and organized manner:

• Problem
• Introduction
• Pre-Lab activity and questions
• Procedure
• Data and Observations
• Analysis and Conclusion

A Teacher’s Guide provides you with lots of helpful information such as tips and suggestions, materials list per class (6 groups), pectinase sources and costs, sample calculations, and answers to all the questions.

Consumables you will need to purchase per lab group: 80 g of unsweetened applesauce and 0.5 mL of pectinase. Pectinase is available from Carolina Biological and on Amazon in both liquid and powder form. Links to these purchase options are included in the product. See the PREVIEW for more details.
