Instructions: Read each mystery passage carefully. Use the Suspect/Clue Tracker to organize your thoughts as you read. Then, answer the questions based on the evidence found in the text.


Mystery 1: The Case of the Missing Class Hamster

Mrs. Gable’s classroom was usually a place of quiet focus, but today it was buzzing with panic. Nibbles, the beloved class hamster, was gone. The cage door was swinging open, and the cedar shavings were scattered across the floor like a miniature snowstorm.
"I fed him last night before I left," Leo said, his face pale. "I remember clicking the latch. I always do!"
Detective Maya and her partner Sam stepped forward to examine the scene. Maya noticed a trail of sunflower seeds leading away from the cage and toward the coat hooks. On the floor next to the wheel, she spotted a small, shiny blue ribbon—the kind used for hair.
Sam pointed at the window. "It's cracked open an inch. Maybe he squeezed out?"
"Hamsters can't reach windows," Maya countered. She walked toward the backpacks. Underneath a bright yellow bag, she found a half-eaten carrot. Nearby, Sarah was sitting at her desk, nervously tucking a loose strand of hair behind her ear. Usually, Sarah wore two blue ribbons, but today, only one remained in her hair.
"I didn't do it!" Sarah cried before anyone even spoke. "I just wanted to show him my new backpack!"

Mystery 2: The Locked Treehouse

Toby, Ben, and Sarah had a strict rule: no one enters the treehouse without all three members present. But when they climbed up on Saturday morning, the "Top Secret" metal box was missing from the corner.
"The door was locked when we got here," Ben noted, scratching his head. "Only we know the code to the keypad."
Sarah looked around the small wooden room. A red woolen scarf was snagged on a splintery branch right outside the window. "Is that yours, Toby?" she asked.
Toby shook his head. "I lost mine at the park yesterday. Besides, I've been wearing my blue hoodie all morning."
On the floor, Sarah found a set of muddy boot prints. They were much smaller than Ben’s size 8 sneakers. Sarah looked at her own boots—they were clean. Then she looked at the ladder. A trail of mud led all the way down.
"Wait," Ben said, pointing to the neighboring yard. "Isn't that Toby’s little brother, Timmy, wearing a red scarf? And aren't those your old boots he's wearing, Sarah?"
Timmy was sitting in his sandbox, frantically trying to pry open a metal box with a plastic shovel.

Mystery 3: Footprints in the Flour

Jamie’s mouth watered as he looked at the chocolate birthday cake cooling on the counter. His mom had spent hours on it for his sister’s party. "Don't touch it, Jamie!" she warned before heading to the garage to find the candles.
Ten minutes later, a scream echoed from the kitchen. A large, jagged chunk was missing from the side of the cake. White flour was dusted across the floor, and in the middle of the mess were two distinct footprints.
Jamie was standing by the fridge, looking innocent. "I just got here! I think Rex did it," he said, pointing to the family’s golden retriever. Rex was wagging his tail, but his paws were perfectly clean.
Mom knelt down to look at the flour. "Rex has paws, Jamie. These are shoe prints. And they look like the tread on your new sneakers."
Jamie looked down at his feet. He had tried to wipe them, but a tell-tale white dusting remained on his laces. Next to the cake, Mom found Jamie’s favorite blue whistle, which he usually kept in his pocket.

Mystery 4: The Vanishing Lunchbox

It was Tuesday—Taco Tuesday—and Noah couldn’t wait for lunch. But when the bell rang and he reached into his cubby, his neon-green lunchbox was gone.
"Someone took my tacos!" Noah wailed.
His friend Chloe helped him look. They checked the lost and found, the cafeteria, and even the principal's office. Nothing. As they walked back, they saw Dylan sitting alone on a bench. Dylan usually had a brown paper bag, but today he was eating out of a bright green container that looked very familiar.
"Hey, is that my lunchbox?" Noah asked.
Dylan looked up, surprised. "No, my mom bought me this one yesterday because my old one ripped. See? It has my name on the bottom."
Noah looked, and sure enough, 'DYLAN' was written in permanent marker. But then Noah noticed something else. A trail of shredded lettuce and a small packet of hot sauce—the specific brand Noah’s dad always used—was lying under the coat rack near Noah's cubby. Behind the rack, he found his neon-green lunchbox, empty, with a single muddy paw print on the handle.

Mystery 5: The Secret Note

Lila found a folded piece of purple paper on her desk. It said: Meet at the big oak tree after school. I have the secret map. It wasn't signed, but the handwriting was loopy and written in glittery silver ink.
Lila looked around the room. Three people were her top suspects. First was Mia, who was currently drawing in her notebook with a silver gel pen. Second was Sophie, who always wore purple headbands and had loopy handwriting in her posters. Third was Gabe, who had been talking about a 'secret map' all week during recess.
Lila watched them during the afternoon break. Mia was using a black pen now, and her notebook was full of straight, jagged lines—not loopy at all. Gabe was frantically searching his backpack, muttering about a lost piece of paper.
When the bell rang, Lila walked to the oak tree. Waiting there was Sophie. She was holding a compass and a piece of purple paper that matched the note.

Mystery 6: The Broken Trophy

The glass display case in the hallway was shattered. The "Best Science Project" trophy lay on its side, its golden base cracked. Principal Miller looked sternly at the three students standing in the hall: Marcus, Elena, and Tyler.
"I was in the gym," Tyler said quickly. He was holding a basketball and was still sweating.
Elena adjusted her glasses. "I was in the library. I have a late slip from the librarian to prove it."
Marcus stayed quiet. He was holding a heavy science textbook and a small, handheld magnet.
Principal Miller looked at the floor. Among the glass shards was a small, round magnet—exactly like the one Marcus was holding. There was also a scuff mark on the floor that looked like it came from a heavy book being dropped.
"Marcus?" the Principal asked.
Marcus sighed. "I was trying to see if the trophy base was magnetic. The magnet stuck too hard, and when I pulled, my textbook slipped and hit the glass. I didn't mean to break it."

Mystery 7: The Midnight Garden Visitor

Mr. Henderson took great pride in his prize-winning hydrangeas. But this morning, his blue flowers were flattened, and his garden gnome, Gnorman, was face-down in the dirt.
"It must be those neighborhood kids!" Mr. Henderson grumbled.
He checked the soft soil around the flower bed. There were no shoe prints, but there were large, circular indentations that looked like heavy pots had been dragged across the ground. Strangely, a small piece of gray fur was caught on a rose bush.
His neighbor, Mrs. Gable, was outside hanging laundry. "Did you see anything last night?" he asked.
"Only the stray cat, and maybe a shadow near the shed," she replied.
Mr. Henderson looked at his shed. The door was slightly ajar. Inside, he found his neighbor's dog, Barnaby, sleeping soundly on a pile of burlap sacks. Barnaby was a large, gray Great Dane. Next to him was a half-chewed garden hose. The circular indentations in the dirt matched the shape of Barnaby's large, heavy paws when he ran.

Mystery 8: The Switched Backpacks

"This isn't mine!" Leo whispered, horrified. His backpack was navy blue with a silver zipper—exactly like the one he was holding, but the contents were all wrong.
He looked around the bus. Two other students had navy blue backpacks. One was Maya, who was currently reading a book about space. The other was Lily, who was wearing a leotard under her jacket and humming a tune from The Nutcracker.
Leo walked over to Lily. "I think we have the same bag," he said.
