Frau Stannik Central Bucks South Unit Plan: Unit 1 Molecules of Life 10th grade Academic Biology Overarching question: What is science and what are the chemical components to life? Standards from PA State Science Standards: • 3.1.A, B • 1.2.A • 3.2.10.A, B, C • 1.4.D • 3.3.10.B • 1.5.A, B, C • 3.7.10.A • 1.6 A, D, E • • • • 2.2.A, B 2.3.A, C 2.5.B 2.6.A Purpose: The purpose of this unit is to explore the nature of matter, the properties of water, carbon compounds, and chemical reactions. (Note: This unit will be prefaced by an introduction to the meaning of science and the process of the scientific method.) Unit Objectives: o Students will be able to . . . • Draw conclusions about “what is science?” • List the steps to the scientific method. • Formulate and revise hypotheses. • Label and define the parts of a microscope. • Practice proper handling and use of a microscope. • Identify that the particles that make up atoms are protons, neutrons, and electrons. • Describe and distinguish between the two main types of chemical bonds, covalent and ionic. • Define a polar molecule. • Classify water as a polar molecule because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. • Explain the pH scale and its’ relationship to living systems. • Utilize various tools to test the relative strengths of solutions (pH). • Define and discover that the role of enzymes is to speed up chemical reactions that take place in cells. • List the four groups of organic compounds found in living things: carbohydrates, lipids, nucleic acids, and proteins. • Classify the four main organic compounds by their key functions: o Carbohydrates are the main source of energy in living things. o Lipids can be used to store energy and form membranes. o Nucleic acids store and transmit genetic information. o Proteins control cell processes and rates of reactions. • Utilize models to depict molecular structure. • Test various organic molecules with indicators.
