Focus On:
The Parole Study: Why did the time of day matter?
Energy Meter: How does thinking use physical fuel?
We will pause to discuss key moments!
The Courtroom Mystery
"Logically, justice should be based on facts. But morning hearings were far more likely to get parole than afternoon ones."
PREDICT: Why do you think the time of day mattered so much?
The Threshold
We have a daily threshold for making decisions. Once it's hit, the quality of our choices drops fast.
Think about a time you felt "brain dead." What time of day was it? What had you been doing?
My Daily Energy Graph
The Mission
Map your typical mental energy from 7 AM to 10 PM.
Label the Map
Identify your Peaks (highest energy) and Valleys (lowest energy).
Decision Markers
Mark where your biggest daily choices happen (School, Homework, Socializing).
Grab Your Graph Paper!
Guard Your Battery
Make Fewer Choices
Plan your outfit or meals the night before to save morning "juice."
The Friend Test
Imagine you're giving advice to a friend. It's less exhausting than deciding for yourself!
Filter Small Stuff
Don't waste high-energy moments on low-stakes drama or tiny details.

Mission Briefing
Track your mental energy levels throughout a typical school day. Step 1: Draw a line graph showing your energy from 7 AM to 10 PM. Step 2: Label your "Peaks" (Highest Energy) and "Valleys" (Lowest Energy). Step 3: Place stars (★) at the times when you have to make your biggest decisions.

Energy Audit
When is your "Peak" energy time?
What usually causes your energy to crash?
Strategic Alignment
Are your hardest choices at your lowest energy?
What's one choice you can move to a "Peak" time?
Tip: Don't spend your "gold" energy on "nickel" decisions!

Lesson Sequence
01
Warm-Up: The Smartphone Analogy (5 Min)
Ask students: "What drains your phone battery the fastest?" (Brightness, apps, TikTok, video). Draw a battery on the board. Transition to: "What is the mental equivalent for your brain? What drains your mental juice?"
02
Video & Discussion (10 Min)
Show the video "How to make smart decisions more easily." Use the pause points on the slides to facilitate discussion:
Pause at 0:52: Why did the judges' decisions change? (Answer: Fatigue/Hunger. It's easier to say "No" than "Yes" when tired).
Pause at 2:03: What does the energy meter represent? (Thinking isn't "free"—it burns actual physical resources like glucose).
03
Main Activity: Energy Graphing (20 Min)
Hand out the Daily Energy Grapher. Students should draw their line graph first. Then, they should overlay their "Decisions" as stars.
Discussion Anchor:
"Look at where your biggest homework or social choices fall. Are you making them when your battery is at 10%? How does that affect your stress?"
Exit
Closure: Charge Check (5 Min)
Students complete the Exit Ticket. Encourage them to pick one habit to automate (like picking clothes the night before) to save energy.
