Description

A skier’s light-headedness at altitude serves as the phenomenon underlying this lab. The human body is a complex equilibrium system that is constantly changing and constantly working to establish and maintain stability. Students will conduct a series of 3 investigations in which they evaluate a chemical system, make modifications to an established equilibrium, and then utilize what they have learned by applying it to the human body to answer the driving question, “What variables affect a chemical reaction system and how does the system respond when something changes?”

Time Requirement
Total, 190 minutes. Teacher prep, 50 minutes. Pre-lab, 20 minutes. Investigations (3), 120 minutes.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Performance Expectation(s)

HS-PS1-6

Crosscutting Concepts
Stability and Change

Disciplinary Core Ideas
PS1.B: Chemical Reactions

Science and Engineering Practices
Constructing Explanations and Designing Solutions

Learning Objectives

  • Create a stable chemical system and observe how the stability of a chemical system changes as a stressor is manipulated.
  • Construct explanations through student-generated sources of evidence to justify that all chemical reactions are in a dynamic equilibrium and can be altered by various conditions.

Prerequisite Knowledge and Skills
Students should be able to write and balance chemical equations; understand, read, and write chemical dissociation equations; and have a general understanding of acids, bases, pH, and chemical kinetics.
