Unit 1 Standards, Objectives, and Tasks GA Performance Standards SCSh3. Students will identify and investigate problems scientifically. e. Develop reasonable conclusions based on data collected. SCSh8. Students will understand important features of the process of scientific inquiry. Students will apply the following to inquiry learning practices: a. Scientific investigators control the conditions of their experiments in order to produce valuable data. SB1. Students will analyze the nature of the relationships between structures and functions in living cells. b. Explain how enzymes function as catalysts. c. Identify the function of the four major macromolecules (i.e., carbohydrates, proteins, lipids, nucleic acids). d. Explain the impact of water on life processes (i.e., osmosis, diffusion). Tasks 1. 2. 3. Create a product that demonstrates your understanding of the characteristics that all living things have. Create a product that compares carbohydrates, lipids, proteins, and nucleic acid as it relates to their monomers, functions, and examples. Create a product that demonstrates your understanding of the effect enzymes have on chemical reactions in the body. Be sure to include a diagram that illustrates the lock & key mechanism of enzymes.
