Organic Compounds-Testing for Nutrients in Foods
Summary
In this in-door lab students will investigate the reaction of functional groups in food nutrients with specific reagents and then be able to test for their presence. They use their knowledge of chemical tests of organic nutrients to help them design their own investigation of identifying unknown nutrients in given foods.
CollapseLearning Goals
1. Students will be able to test for sugars, starch, proteins and lipids in foods
2. SWBA to use science process skills and design their own investigation

Context for Use
This is a lab that will spans over 2-3 class periods instead of one because students are English Language learners so need more explanation and demonstration time before activity can be successfully done.
Description and Teaching Materials
Students will test which foods contain sugars, starches, proteins and lipids. It is a guided inquiry lab where students learn what inquiry is or review inquiry and are guided to do inquiry on their own. Students will identify science process skills they will be using. Assessment will be based on how far they can do this activity successfully. Instructor's notes and worksheets (Microsoft Word 83kB Jun3 11)
