The Tiny Seed Mystery
Read the night before Day 1 | A science story
“I found a treasure!” Malik called.
Nia hurried over. In his palm lay a small, striped sunflower seed. It had
fallen beside a pot in their school garden in Trenton.
“That?” Nia asked. “It looks like a tiny pebble.”
Their teacher, Ms. Rivera, smiled. “A pebble cannot grow leaves. A
seed might. Let’s solve its mystery.”
Nia peered through a magnifying glass. She saw a pale stripe and a
pointed end. No leaves. No roots.
“How could something this small become a tall sunflower?” she
wondered.
“The beginning is already inside,” Ms. Rivera said.

A Young Plant and Its Packed Lunch
This model shows a seed’s inside parts. The drawing is much larger than a real seed.
Ms. Rivera opened a picture book about seeds.
“A seed coat is a covering that protects the parts inside,” she explained.
“A sunflower seed has an outer shell too.”
“Like a jacket?” Malik asked.
“A protective jacket,” she said. “Inside the seed is an embryo. That
means a tiny young plant.”
Nia leaned closer to the picture. “So the plant begins small before we
can see a sprout!”
“Yes. The seed also holds stored food. The young plant uses it as it
starts growing.”
“A packed lunch for a plant!” Malik said.
Nia laughed. “A very, very small lunch.”
“That’s a useful way to remember it,” Ms. Rivera said. “Later, green
leaves help the growing plant make its own food using light.”

A Mystery Worth Watching
Ms. Rivera showed them the sunflower’s life cycle: the stages it goes
through during its life.
“A seed can sprout into a seedling, a young plant. It grows into an adult
sunflower. Later, the plant can make new seeds.”
“And those seeds can grow new sunflowers?” Nia asked.
“If conditions are right. Not every seed grows. The original sunflower
eventually dies, but new plants can continue the cycle.”
Malik looked at the empty pot. “Can ours grow by tomorrow?”
“A whole sunflower takes many weeks or months,” Ms. Rivera said.
“We’ll watch for small changes first. Water, air, and suitable warmth
help a seed begin growing.”
Nia carefully handed the seed to her teacher.
Now it looked less like a pebble and more like a mystery worth
watching.
She had one question ready for class: “Which part will appear first—a
root or a leaf?”
