These STEM Air Bag activities engage students in hands-on, discovery-based learning as they work through the design and construction of an airbag. These inquiry-based research activities integrate stoichiometry and reaction rates, while challenging students to overcome design difficulties. Once students have developed their airbag, a pressure sensor is attached and students are tasked with finding the stoichiometric ratio of reactants to products.
This version is the Teacher License (one license for all your classes) and includes a spiral-bound teacher manual.
Activities in the module are designed to help students make important decisions regarding 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 explore pressure and volume through research activities that incorporate stoichiometry and reaction rates. After overcoming the challenges of constructing an airbag, students will use a pressure sensor to determine the stoichiometric ratio of reactants, which allows them to determine what pressure will inflate their air bag the fastest. Finally, students will discuss how to improve their designs.
