Zombie Detective Slides Case File #001
Zombie Detective Agency
Cracking the code of Active vs. Passive Voice.
Crime Scene Investigation
Witness Statement A:
"The detective solved the case."
Witness Statement B:
"The case was solved by the detective."
What's the difference?
Both sentences mean the same thing.
One feels faster and more direct.
Who is DOING the action in Statement A?
Anatomy of Active Voice
THE DOER
(Subject)
THE ACTION
(Verb)
THE RECEIVER
(Object)

THE ZOMBIE TEST
If you can add the phrase "...by zombies" after the verb and the sentence still makes sense, it's PASSIVE VOICE .
1
"The brain was eaten by zombies."
PASSIVE!
2
"Zombies ate the brain by zombies."
ACTIVE!
Detective Practice

AGENT BRIEFING
Detectives, we have reports of "Passive Sentences" cluttering our files. They hide the person responsible for the action! Use the Zombie Test to identify them. If you can add "...by zombies" after the verb and it still makes sense, you've found a passive sentence.
Part 1: Diagnostic Testing
Apply the Zombie Test to each sentence. Check the box if the sentence is Passive . Leave it blank if it is Active .
1. The ancient scrolls were stolen from the museum.
Test: The scrolls were stolen
2. The chef prepared a five-course meal for the guests.
Test: The chef prepared
3. A massive meteor was spotted by the astronomers.
Test: A meteor was spotted
4. The team won the championship game on Saturday.
Test: The team won
5. Instructions were given to the new recruits.
Test: Instructions were given
Part 2: Evidence Analysis
In your own words, explain how the Active Voice version of a sentence differs from the Passive Voice version. Why might a detective prefer one over the other?
Part 3: Visual Reconstruction
Read the two sentences below. Draw a simple sketch in the boxes that represents the "Focus" of each sentence.
Active Focus
(Sketch the subject performing the action here)
"The detective investigated the clue."
Passive Focus
(Sketch the object receiving the action here)
"The clue was investigated by the detective."
Detective's Summary Challenge:

The Sentence Flip
Mastering the mechanics of writing conversion.
Why Flip?
More Energy
Active sentences feel faster and more exciting to read.
Shorter Length
Flipping usually removes unnecessary "helper" words.
Total Clarity
The reader knows exactly who is responsible immediately.
Efficiency Test:
Passive (9 words):
"The delicious pizza was eaten by the hungry students."
Active (6 words):
"Hungry students ate the delicious pizza."
The 3-Step Flip Blueprint
1
Hunt the Doer
Find the person or thing hidden after the word "BY".
"...by the dog."
2
Lead the Way
Move that hidden doer to the very front of the sentence.
"The dog..."
3
Trim the Fat
Delete "was/is/be" and change the verb to its strongest form.
"The dog ate..."
Flip Workshop: Drill 01
Passive Construction:
"The ancient ruins were visited by many tourists."
Step 1: Who is the Doer?
Many tourists
Final Active Flip:
?
What is the active version? Discuss!
The Ghost Subject
Sometimes, the passive voice hides the "doer" completely! We call this an Unknown Agent.
"The bank was robbed."
To flip this, you must invent a logical subject:
Option A:
"Thieves robbed the bank."
Option B:
"A masked man robbed the bank."

Circuit 01: Passive
"The national anthem was sung by the world-famous pop star."
Circuit 02: Passive
"New rules for the cafeteria were announced by the principal."
Circuit 03: Passive
"The mysterious glowing object was discovered by a young hiker."
Level 02: The Ghost Subject Challenge
Danger: Missing Agents
In these sentences, the "doer" is completely hidden. To flip these into active voice, you must invent a logical subject (e.g., The police, Someone, A mysterious figure).
"The window was broken."
Subject missing!
New Active Flip:
"Dinner is served at 6:00 PM."
Subject missing!
New Active Flip:
"The lost dog was finally found."
Subject missing!

Workshop Reflection
Compare the passive sentences above to your active flips. How much shorter are your new sentences on average? Why does this make your writing more powerful?

Subject Safari Slides Expedition #03
Subject Safari
Hunting for hidden actors in the tall grass of vague writing.
The "Vague Verse" Mystery
The Foggy Version:
"There was a loud noise in the trees. There were shadows moving across the path. It was a terrifying moment for the hikers."
Vague, slow, and hides the action!
The Safari Version:
"A thunderous roar shook the trees. Dark shadows lunged across the path. The hikers trembled in fear."
Active, direct, and full of life!
Spotting the "Filler" Camouflage
Some sentences use expletives—placeholder words that delay the real subject.
"There is"
Hides the subject behind a state of being.
"There are"
Multiple subjects hidden later in the grass.
"It is"
Points to nothing in particular. Very vague!
The Extraction Technique
1
Scan the Sentence
"There is a huge spider on my tent."
Found the real subject!
2
Move it to the Front!
"A huge spider sits on my tent."
Stronger verb + Active lead!
Live Safari Drill
Extract the real subject and lead with it!
Construction:
"There are many reasons to visit the rainforest."
Your Active Lead:
"Many reasons..."
Construction:
"It is important that you stay on the trail."

Part 1: Spotting the Camouflage
Sentences starting with "There is," "There are," or "It is" often hide the real subject deep in the brush. Underline the real subject in each sentence below.
There are three rare birds nesting in the mahogany tree.
There is a poisonous spider hiding inside your hiking boot.
It is likely that a heavy storm will arrive by nightfall.
There were dozens of monkeys swinging through the canopy.
Part 2: Active Extraction
Extract the real subject and start your sentence with it. Use a powerful action verb to make the sentence more exciting!
Original: "There is a jaguar stalking its prey."
Original: "There are many secrets hidden in the jungle."
Original: "It is necessary for us to clear the path."
Part 3: The Safari Narrative
Read the boring, vague field notes below. Rewrite the entire passage to eliminate all "There is/are" openers. Make the jungle come alive with active subjects!
"There was a thick mist over the river. There were crocodiles resting on the muddy banks. It was a dangerous place for a traveler. There was a single boat waiting for us."
Expedition Check-Out
Think about the rewrite you just did. Why does leading with the "Mist," the "Crocodiles," and the "Boat" make the story feel more immediate than starting with "There was"?
Perspective Prober Slides Analysis Lab #04
Perspective Prober
Analyzing how voice shapes the truth in the real world.
The Power of Choice
Voice isn't just a grammar rule. It's a rhetorical tool that authors use to change what you notice first.
Active Voice
Focuses on:
THE ACTOR
Puts the blame or the credit directly on the person doing the thing.
Passive Voice
Focuses on:
THE EVENT
Emphasizes the result, often hiding the person responsible.
Case File: The Broken Trophy
Statement A (Active):
"Leo knocked over the expensive trophy."
Statement B (Passive):
"The expensive trophy was knocked over."
The Analysis Question:
In Statement B, do we know who broke it?
Which statement would Leo's parents prefer to hear?
Which statement is "hiding" the truth?
When Passive is Actually Useful
Scientific Reports
"The liquid was heated to 100°C."
It doesn't matter WHO heated it; the process is the focus.
Unknown Actors
"The cave paintings were created thousands of years ago."
We don't know the specific artist, so passive works best.
Official Notices
"Laptops must be returned by Friday."
Focuses on the rule and the object rather than the person.
The Objectivity Trap
Many writers use passive voice to sound more scientific or objective. But sometimes, they are just avoiding responsibility.
Avoiding Blame:
"Mistakes were made during the study."
Taking Ownership:
"We made mistakes during our study."
Which one feels more honest? Why?
Open Case File: Analysis
It's time to analyze real-world reports. Look for the "hidden actors" and uncover the intent behind the voice.

Research Case: Rhetorical Intent // Lab 04
Lead Analyst:
Station:
Evidence File A: The Playground Collision
Compare these two accounts of an accident on the soccer field.
Account 1 (Active)
"Max ran into Chloe while chasing the ball, causing her to fall and scrap her knee."
Account 2 (Passive)
"Chloe was knocked over during the chase for the ball, and her knee was scraped."
1. Responsibility Analysis:
In which account is it clearer who is responsible for the scrape? Explain why.
2. Empathy Target:
Which account makes you feel more sorry for Chloe? Why does the sentence structure change your feeling?
Evidence File B: Science Journal
"The chemical solution was poured into the beaker. A bright blue reaction was observed by the students. Finally, the data was recorded in the logs."
3. Functional Passive:
This passage is almost entirely passive. Why might a scientist prefer this over saying "I poured the liquid" or "We saw the color"?
4. The Ownership Flip:
Rewrite the science passage in Active Voice . Does it sound more or less "professional"?

Crime Report Cards Crime Report Analysis Cards
Lesson 4 Hook: Perspective Comparison
"Detectives: Compare the tone and focus of these two reports. One uses Active Voice to identify a suspect; the other uses Passive Voice to focus on the object of the crime. How does your opinion of the incident change based on the voice?"
Report Alpha Active
The Vandalism
"The local high school student spray-painted the side of the community center last night. He ruined the mural that the neighborhood kids painted last summer."
Analysis Note:
This version points a finger directly at the 'doer'.
Report Beta Passive
The Incident
"The side of the community center was spray-painted last night. The mural, which was painted last summer, was ruined in the incident."
Analysis Note:
This version emphasizes the damage rather than the person who did it.
Debriefing Questions
Q1:
Which report sounds more like an accusation?
Q2:
Why might a newspaper choose the Passive report?
Q3:
Which report feels more "objective" or scientific?
