Chapter 3 Cell Processes and
Energy
~~Section 1 Chemical Compounds in Cells~~
Students will start section 1 by examining different materials and their ingredients: Sun Block, Chalk, Water, Salt and Baking Soda using the Periodic Table to try and figure out what chemical compounds or elements the products are composed of. As a class we will discuss the difference between an Element and a Compound. We will also look at the difference between Organic and Inorganic Compounds and the importance of water to the function of cells. Carbohydrates, Lipids, Proteins, and Nucleic Acids are the main organic molecules in living things, we will discuss where these molecules are found, their structures, and functions within cells.
~~Section 2 The Cell in its Environment~~
Students will learn that Diffusion is the main method that small molecules use to move through the cell membrane, why Osmosis is important to cells, and the difference between Active and Passive Transport in cells.
~~Section 3 Photosynthesis~~
To begin this section we will discuss a source of energy, the Sun, and how nearly all living things rely on this source directly or indirectly for their energy. Students will then learn what happens in the the 2 step process of photosynthesis as well as the Photosynthesis Equation.
~~Section 4 Respiration~~
We will start by comparing the 2 types of respiration, then what events occur in the 2 stages of respiration. Students will then move on to the different types of Fermentation and learn that this another way organisms can obtain their energy.
~~ Chapter Project~~
Students will become the raw materials or products of Photosynthesis and Respiration to create an assembly line in which they will be responsible for their individual jobs. Through this demonstration students will talk out which materials are combining and which materials are being broken up to form the stages of these two processes.
