Overview: In this investigation, students will use standard indicators to test for carbohydrates, lipids, proteins and nucleic acids. This lab can be easily expanded to include student-centered investigations.
Curriculum Connections: macromolecules, hydrolysis and dehydration synthesis, nutrient cycling
Experimental Timing: From start to finish this lab takes 120 minutes. However, there are many good stopping points in this protocol that make it possible to complete the lab in a series of 45-50 minute periods. For additional information, see "Instructor Planning Guide" in the Teacher Materials.
Specialized Equipment Required: hot plate or microwave • UV or blue light source • p200 micropipette (optional)
