Energy Economy
Part of Module 2 of Bitcoin for Juniors →
PROCEDURE
OPENING
- Prepare a large Energy Tracker graph on the board or poster:
- Horizontal axis: Time of Day (Sunrise → Sunset)
- Vertical axis: Energy Level (Low → High)
- Lay out flashcards so they are visible and easy to access.
- Prepare individual handouts and writing materials.
- Ensure clear space for students to approach the board safely.
PRE-ACTIVITY
3-5 minutes
- Introduce the idea:
- Ask the class:
- Make it personal:
- Use quick show-of-hands questions:
Objective In Student's Words
- "See how my energy changes during the day and what uses or gives me energy."
ACTIVITY
30 minutes
Setup
- If possible, use visual aids to illustrate time and energy tracking (See Appendix A)
- Return to the Energy Tracker graph previously drawn.
- Explain that the horizontal line shows the day from sunrise to sunset.
- Explain that the vertical line shows energy from low at the bottom to high at the top.
- Ask students to name examples of activities they do in the morning, afternoon, and evening.
Model
- Choose one flashcard such as eating breakfast.
- Ask: "When do you usually do this?" and "Does this give you energy or take energy?"
- Place the card on the graph using student input.
1. Group Graphing
15 minutes
- Show one activity card at a time.
- Ask: "When do you usually do this?" and "Does this give energy or take energy?"
- Use class consensus to place the card left to right based on time of day and up or down based on energy level.
- Repeat with 8–10 activity cards.
- Encourage discussion and disagreement by reminding students that activities can feel different for different people.
- Step back and review the completed graph.
- Ask: "What do you notice?" "When does energy seem highest?" "What happens later in the day?"
2. Individual Graphing
10–15 minutes
- Distribute Energy Tracker handouts. (See Appendix B)
- Instruct students to think about a typical day, choose 4–6 activities they usually do, and plot them on their own graph using words or drawings.
- Support non-writers by providing printed images to glue or tape, allowing drawing instead of writing, and pairing with a buddy if needed.
Reflection
2 minutes
- Ask: "What time of day do you have the most energy?" "Which activity uses the most energy?" "What helps you feel more rested?" "How could you use your energy better?"
- For older students ask: "What happens if all your energy is used in the morning?" and "How can we save energy for things that matter?"
FOLLOW-UP
3 minutes
Content review with students
- Review that energy changes during the day, activities affect energy differently, and people have different energy patterns.
- Connect forward by explaining that these patterns affect how we work, rest, play, and make choices.
CLOSE
5 minutes
- Collect handouts and materials.
- Remove or clear the class graph if needed.
- Thank students for participating and reinforce the message that energy is limited and how we use it matters.
NOTES
Classroom management
- Use clear turn-taking rules, limit placement decisions to a few seconds, encourage listening and respectful disagreement.
Extensions & Sponge Activities
- Compare school day vs weekend energy graphs, small-group graph comparisons, physical energy demo using crouch for low energy and stand tall for high energy.
- Use the same principles to look at energy across longer time scales (weekly, seasonally, lifespan etc)
Differentiation
- Younger students: Optional partner support for younger students, drawing and image cards.
- ELL/Accessibility: visuals, modeling, partner support.
- Safety: supervise movement near the board.
