Biotechnology Curriculum Freshmen Year: pH
During this unit, students will be learning about the terms acid and base. Water is neutral and can be formed from equal amounts of acid and base. What makes a solution an acid? What makes it a base? How is this important to living things? Most living things exist in a pH around 7.0, which is neutral. If they are exposed to either basic or acidic solutions they will be injured or die. Students will learn how to measure the amount of acid or base present in a solution using an indicator dye present in red cabbage.
