Quiz & PSA Script Guide

Teacher Script (5 minutes)

Teacher: “Great work on the quiz, everyone! Take a moment to look over your answers one more time. Today, you’ll turn one of your quiz facts into a short, powerful public service announcement—a PSA—to help others keep their hearts healthy.

Step 1: Review & Choose a Key Fact
Teacher: “In your group, share which question you got right and which one surprised you most. Then decide together on one heart fact you want to highlight in your PSA. It might be: “Your heart beats about 100,000 times a day,” or “Exercise helps strengthen your heart muscle.”

Possible Student Responses

• “I was surprised that our heartbeat changes when we exercise!”
• “I want to talk about how valves keep blood flowing the right way.”

Teacher Prompt: “Why did you pick that fact? How will it help someone make a healthier choice?”

Step 2: Plan Your 30-Second Script
Teacher: “Use this simple outline to build your PSA in 30 seconds:

1. Hook (5 seconds): Start with a quick question or surprising fact.
   • Example: ‘Did you know your heart beats so fast, it could circle the Earth in a single day?’
2. Key Fact (10 seconds): State your chosen fact clearly.
   • Example: ‘That’s right—your heart pumps 100,000 times every day to keep you alive!’
3. Why It Matters (8 seconds): Explain why this fact should matter to your audience.
   • Example: ‘A strong heart means more energy for sports, studying, and having fun.’
4. Call to Action (7 seconds): Tell people what they can do right now to protect their heart.
   • Example: ‘So, lace up your sneakers and get moving—your heart will thank you!’

Teacher Prompt: “Write one sentence for each of these four parts. Keep it short, clear, and catchy.”

Step 3: Peer Check & Polish
Teacher: “Once you have your draft, read it aloud to your group. Ask:

• ‘Does this grab our attention?’
• ‘Is our fact accurate and easy to understand?’
• ‘Does our call to action feel inspiring?’

Teacher Prompt: “If something feels too long, trim a word or two. If it’s unclear, swap in a simpler phrase.”

Teacher: “You’re ready to move on to storyboarding in just a couple minutes. Fantastic! Keep your script in front of you so you can match each line to a visual frame.”

PSA Storyboarding Activity

Objective: Translate your PSA script into a clear, engaging visual plan.

Materials:

• Printed storyboard templates (3–4 frames each)
• Colored pencils or markers

Instructions:

1. Distribute one PSA Storyboarding sheet and drawing tools to each group.
2. For each line of your script, create a frame:
   • Sketch the key visual scene.
   • Below the sketch, write the exact narration or dialogue.
   • Note any sound effects or on-screen text.
3. Follow the flow of your script:
   • Frame 1: Hook (grab attention)
   • Frame 2: Key Fact
   • Frame 3: Why It Matters
   • Frame 4: Call to Action
4. Use arrows or numbering to show the sequence.
5. Review with your group:
   • Is each frame clear and easy to understand?
   • Does the storyboard match your script timing?
   • Are visuals and text engaging?

PSA & Quiz Rubric Answer Key (#psa-quiz-rubric-answer-key)

This combined answer key includes two parts:

1. Quiz Answer Key – Correct answers with reasoning for each question.
2. PSA Evaluation Rubric – Criteria and scoring levels for grading student PSAs.

Part 1: Quiz Answer Key (5 points)

Each correct response is worth 1 point.
Use the explanations below to verify student understanding.

Step-by-Step Thought Processes:

• Q1: Recall the four anatomical chambers.
• Q2: Know that ventricles differ in destination; left goes body, right goes lungs.
• Q3: Understand left-side valve names and positions.
• Q4: Calculate average beats/minute × minutes in a day.
• Q5: Distinguish between aerobic and anaerobic exercise effects.

Part 2: PSA Evaluation Rubric (12 points)

Grade each group’s PSA (script + storyboard) using four categories.
Each category is scored 0–3 points. Total PSA score = 12 points.

Scoring Guide:

• Total PSA Points = Sum of category scores (0–15).
• Quiz Points = Number of correct quiz answers (0–5).
• Overall Lesson Score = Quiz Points + PSA Points (max 17).

Use this answer key to:

• Quickly score quiz submissions against correct answers and reasoning.
• Evaluate each group PSA for factual accuracy and effective communication.
• Provide targeted feedback (e.g., “Your fact was accurate, but your hook needed more impact”).

Teacher Tip:

• Circulate during storyboarding to check alignment with rubric categories.
• Encourage groups that score low in Creativity to brainstorm bolder hooks or visuals.
• Use rubric totals to identify students needing further support in heart-health concepts or communication skills.
