Product Details

Capture your students' attention by studying how a self-inflating balloon works! Your students will have fun investigating this novelty balloon, by using stoichiometry and the ideal gas law. Students then apply what they learn to make their very own self-inflating balloon. Additionally, students explore the concepts of limiting and excess reagents and acid-base chemistry. Have fun with this engaging lab experiment! Complete for 30 students working in pairs.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
