Reteach tomorrow: Sourcing
19 of 27 students fell short. Named who wrote the document but never said why that author’s purpose or audience matters to the argument.
Plan: Model sourcing on Documents 2 and 6, then a 10-minute sourcing drill.
Sourcing: 8 full credit, 0 partial, 19 missed.

Read the class, row by row
Who earned each rubric point, the mistakes the class shared, and the one thing to reteach tomorrow.
Every point explained. You check any of them.
- Score any response yourself, row by row. Fivefold tracks how often it agreed with you, so you know when to trust it.
- Students see the same breakdown and revise while the task is still fresh.
- The scorer reads the answer, never the student’s name or email.
Strong experimental design answers. The justification describes the result instead of explaining it.
- Named the variable and the reason it has to stay fixed.
- The prediction is clear and matches the setup.
- When a question says justify, name the mechanism: what happens to the protein and why that changes the rate.
Part (a): Independent variable
1/1 points, full creditTemperature is the variable the student changes on purpose.
From your response- The temperature of the water bath
Rubric criteria
Identifies temperature as the independent variable.
Part (b): Controlled variable
1/1 points, full creditNames a controlled variable and explains how it would change the result on its own.
From your response- more of it would make more oxygen even at the same temperature
Rubric criteria
Names a variable to hold constant (hydrogen peroxide concentration or volume, amount of catalase, pH, time) AND explains that changing it would also change the oxygen produced, so the effect of temperature could not be isolated.
Part (c): Prediction
1/1 points, full creditCorrect direction, compared with the right control.
From your response- Less oxygen would be produced
Rubric criteria
Predicts that less oxygen (or none) is produced than with unheated catalase.
Part (d): Justification
0/1 pointsThis restates the prediction. It does not say what heat does to the enzyme, or why the effect lasts after cooling.
From your response- the enzyme works slower when it gets hot
To earn the missing pointSay that 80°C denatures catalase: heat breaks the bonds holding its shape, the active site no longer fits hydrogen peroxide, and cooling does not restore it.
Rubric criteria
Explains that heating denatures catalase: it disrupts the bonds that maintain the protein’s shape, the active site no longer binds hydrogen peroxide, and the change is not reversed by cooling. "The enzyme slows down when hot" does not earn the point.

Logins stay personal
A teacher account works on two devices at once, and mass downloading is slowed and flagged.
Common mistakes
- “Cooling the enzyme fixes it.” Denaturing changes the active site’s shape, and it does not snap back when the temperature drops.
- “Enzymes get used up.” They are catalysts. The same enzyme molecule works through reaction after reaction.
- “A faster rate means a bigger ΔG.” Enzymes lower activation energy. The overall energy change of the reaction stays the same.
On the exam
Expect a graph of rate against temperature or pH, and a question about why the curve falls on one side.
