Section 1: Biology – Human Physiology
Concept Check:
1. The sinoatrial (SA) node is often called the heart’s natural pacemaker.
o
What ion movement (Na⁺, K⁺, Ca²⁺) is most critical to the depolarization phase of
its action potential?
2. Compare and contrast skeletal muscle fatigue and cardiac muscle endurance.
o
Why can the heart keep beating for a lifetime, but your quads burn out after a
sprint?
Section 2: History – Civil War Snapshot
Quick Facts:
The Missouri Compromise (1820) allowed Missouri as a slave state and Maine as a free
state, preserving the Senate balance.
Sherman’s March to the Sea (1864) devastated Georgia’s infrastructure, aiming to break
Confederate morale.
The Appomattox Court House (1865) marked General Lee’s surrender to Grant,
effectively ending the war.
Question:
What role did total war strategy (like Sherman’s March) play in accelerating the end of the Civil
War?
Section 3: Psychology – Social Cognition
Term Match:
Priming – Prior exposure influencing later behavior.
Attribution theory – How we explain causes of behavior (internal vs external).
Attitude-behavior consistency – Stronger when specific attitudes match specific
behaviors.
Applied Question:
Imagine you just walked into a bakery. The smell of cinnamon rolls makes you suddenly think
about calling your grandmother. What psychological process is at play?
Section 4: Math – Probability
You flip a fair coin 3 times.
Probability of getting exactly 2 heads?
Probability of at least 1 tail?
Bonus: Generalize the formula for k heads in n flips.
Section 5: Critical Thinking – Ethics Thought Experiment
The trolley problem:
A runaway trolley is heading toward 5 people tied to the tracks. You can pull a lever to
divert it, but it will kill 1 person on another track.
Do you pull the lever?
Is your reasoning utilitarian (minimize total harm) or deontological (some actions are
always wrong)?
This kind of document mixes recall (definitions, facts), application (scenarios), and reasoning
(thought experiments). It’s like throwing your brain into a wind tunnel and seeing which
concepts stick.
Would you like me to turn this into a practice test format (with multiple-choice and shortanswer) or keep it as a study sheet with prompts like this?
