Reactor RescueChemical Reactions & Energy TransferGrades 9-12
Storyline
Phenomenon
A chemical reactor is producing unstable results as reaction rates fluctuate under changing conditions. Students explore how altering temperature, concentration, or catalysts affects equilibrium and system stability.
Science and Engineering Practices
Planning and Carrying Out Investigations
Analyze simulated reactor data to identify variables affecting reaction rates.
Analyzing and Interpreting Data
Compare graphical data to determine equilibrium conditions.
Constructing Explanations and Designing Solutions
Explain how modifying environmental conditions can restore equilibrium.
Using Mathematics and Computational Thinking
Calculate reaction rate changes and balance multiple factors.
Crosscutting Concepts
Stability and Change
Understand how chemical systems seek balance and how small changes can shift equilibrium.
Cause and Effect
Relate observed changes in reaction output to specific environmental adjustments.
Disciplinary Core Ideas
PS1.B: Chemical Reactions
Chemical reactions occur when atoms rearrange; rates depend on temperature, concentration, and catalysts.
PS3.B: Conservation of Energy and Energy Transfer
Energy changes affect the direction and rate of chemical reactions.
