Biology 20 Nurtient Lab
Date: Nov 15, 2012
Grade/Subject/Topic: Biology 20, Unit C
Time Allotted: 60 min
Learning Objectives: students will...
GLO: Students will explain how the human digestive and respiratory systems exchange energy and matter with the environment.
SLO: 20–D1.2k describe the chemical nature of carbohydrates, lipids and proteins and their enzymes; i.e., carbohydrases, lipases and proteases
Students will describe how nutrients can be identified using different indicators.
Resources
Ritter, B., Burley, K.L.,& Fraser, D. (2007). Biology. Toronto: Thomson Nelson.
Materials Needed:
PowerPoint, lab materials: test tubes, Bunsen burner, thermometer, goggles, 10mL graduated cylinder, milk, water, oil, fruit juice, egg, gelatin
Procedure:
Introduction (10 total mins):
Review the day
Attendance
Discuss the cumulative exam with all three units next Wednesday
Discuss expectations for this lab
Discuss safety procedures
Body (40 total mins):
Get students into their groups, and have each group sit at a lab bench with the materials
Have students get their goggles on
Explain the procedure and the purpose of the lab: hand out worksheets to students
Discuss students roles
Work time on lab
Clean up
Closure (10 total mins):
Discuss results
Note to hand in assignments
Lab worksheet is due tomorrow
Reflection
This lab went very well and I feel that organization was key to having a successful class. Before the class began I had groups already made up with specified student roles. The lab materials were already distributed on the lab benches and a detailed procedure for the lab was laid out. Before students began working on the lab I also discussed what they need to do and the importance of the safety procedures. I believe that being prepared and foreseeing problems that may arise in the class is very important to have successful class. During the lab today a test tube was broken, and fortunately no one was hurt. Students knew the procedure for broken class and the little incident was quickly cleaned up.
Next time if I was to do this lab again, I would have more nutrients to test. I didn’t have any starches so all the iodine tests were negative. Also, we only had 60 minutes to complete this lab so the students were rushing through their tests to complete them and clean up before the bell. Doing this lab in a longer period or breaking the lab up into sections would give students time to explore the lab more indepthly.

Students tested different nutrients by adding indicators to test tubes and analyzing the results.
