This enzyme lab is one of my favorite Biology labs ever! You'll receive a teacher's guide, student lab handout, answer key, 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 any secondary science class that studies enzymes. 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 also: design and carry out their own experiment write a formal lab report 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 1 mL of pectinase. Pectinase is very affordable and 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.
