This "fill in the blank" style set of notes accompany the power point presentation called "Carbohydrates Lipids Proteins and Nucleic Acids". These notes are designed to engage your students while you are teaching. Students will fill in blanks as you go through the power point and they will draw and label diagrams of the molecules. This lesson is designed for 9th grade Biology as an introduction to carbon based molecules. Included is a practice test question to serve as a review of the concepts learned.
