This module guides students through the engineering design process, culminating in the construction of an air bag. This version is the Teacher License (one license for all your classes) and includes a spiral-bound teacher manual.
How It Works
Activities in the module are designed to help students make important decisions including the variables that affect pressure, amounts and concentration of reactants, and the factors that affect the rate of a chemical reaction.
- Understanding Pressure
- Mole-to-Mole Ratios
- Variable Volumes
- Stoichiometric Calculations
- Reaction Rate
In these activities students will explore pressure and volume. They will perform research activities around stoichiometry and reaction rates. After overcoming the design challenges of constructing an airbag and attaching a pressure sensor, they will determine the stoichiometric ratio of reactants to produce the correct amount of pressure to inflate their air bag in the shortest time possible. After testing their air bags, students will suggest ways to improve their design.
