Science through a story
What we will explore
The characters' words and actions are fiction. Real science appears in Science notes, and things to try appear in Observation activities.
- Distinguish what a seed needs to germinate from when a growing plant needs light.
- Observe a bean's roots and leaves and find out what they do.
- Observe safely with a grown-up and separate predictions from what you actually see.
- Leave room for uncertainty and choose a question to investigate next.
Scene 01
A Beginning Smaller Than a Pebble
Coco tilted their head at the empty pot in Heart Garden. Mimi opened a paper packet and put three red kidney beans on a little dish. Window light shone on their smooth coats.
“Could a garden really begin inside one of those?” Coco asked. Mimi opened a blank notebook. “Let's look before we write the answer.”
Coco wrote, “A forest tomorrow!” Then the pencil stopped. Below the words, Coco drew the three beans. The beans in the drawing were much bigger than the real ones. “I've made them bigger so we can see them.” Together they left plenty of room below the first picture.
Scene 02
A Tiny Packed Bag
Mimi opened a reference picture showing the inside of a seed. Coco looked from the picture to the beans and back again. “There was something we couldn't see from the outside.”
“It looks like a travel bag,” Coco said. “As though a little traveler had packed ahead.” Mimi smiled. “That's a comparison you invented. There isn't really a zipper or a lunch box inside.”
Coco divided a notebook page into two spaces: an imaginary bag on one side, the seed picture they had checked on the other. They did not cut open a seed. “Imagination and facts can share a page,” Coco said, “as long as we know which is which.”
Scene 03
A House You Can See Through
Clean equipment, checked by the gardener, waited on the table. Coco held the clear cup toward the window. “We can see through the wall! We won't have to keep digging things up.”
Mimi fitted a damp paper towel inside. Coco watched the three beans, spaced apart near the cup wall. On the outside, Coco drew one dot beside the first bean, two beside the next, and three beside the last, so they could tell them apart.
They set the cup on a steady shelf inside the garden room. “Must we stay here all day?” “Let's have our walk, too,” said Mimi, clearing away the dish. They wrote the seed type and starting date on the cup. It did not need anyone's name.
Scene 04
A Morning That Looks the Same
The next morning, Coco hurried toward the cup, then slowed down. The beans looked much as they had before. “Did we forget something?” Coco's pencil hovered above the page.
Mimi did not cover the space where Coco was about to write “Failed.” Instead, Mimi asked, “How could we describe only what we can see?” Coco looked again. “No root is visible today.”
Together they read the seed packet and the instructions. Coco left the enormous tree drawn in tomorrow's calendar square, but added a question mark. “That was my prediction.”
Scene 05
The First White Tip
After several visits to the cup, Mimi called Coco over. A small white tip had appeared from the bean beside one dot. Coco held a magnifier outside the cup.
“Could we pull it closer?” Coco raised a hand, then stopped. Mimi moved aside. Looking from a little farther around the cup made the thin shape easier to follow.
Coco drew it very large and added a mark to show that the drawing was enlarged. “Someone might think it was a gigantic root.” The little tip inside the cup gave no answer to either of their voices.
Scene 06
Instead of Asking Who Won
The root beside one dot grew longer, but the other beans did not look the same. Coco began to draw a crown, then turned the pencil over. “This bean hasn't won a race.”
Mimi made three spaces and drew each bean as it looked. Coco did not fill the empty spaces with imagined roots. A small question mark could stay beside something they could not yet see.
“They share a cup, but they look different.” “Let's record the difference.” They placed yesterday's drawings alongside today's. There were no marks for getting the right answer, but there were more questions than before.
Scene 07
The Day the Leaves Met the Light
A little stem rose upward, and one day a pair of thin green leaves opened. Coco held out both hands. “It looks like a greeting.” Mimi laughed and waved to the little leaves, too. “Hello, new leaves!”
They looked at the leaves in a bright place. Light from the window touched their edges. Coco almost covered the drawing with magical sparkles, then drew the veins they could actually see instead.
“I thought plants ate soil,” Coco said, writing a question mark beside the reference page. Mimi left the question there. Beneath the leaf drawing was room for something new they had learned.
Scene 08
Almost a Puddle
Coco arrived carrying water. “Another cupful today!” Mimi pointed toward the bottom of the observation cup. The towel was still wet. Coco set the water down before pouring.
“I thought we should do it because we did it yesterday.” “Let's look at today before we choose,” said Mimi. Beside the notebook's water-drop drawing, they added, “Check first.”
Coco considered the water in the jug. What was available might be different from what was needed. Setting a helpful-looking tool down again had become part of their investigation.
Scene 09
Hands Preparing a New Home
A small pot and saucer stood beside the observation cup. While the gardener prepared to move the seedling, Coco cleared a space and Mimi collected the scattered tools. This time, neither reached in first to prove they could do it alone.
The notebook held more than pictures of things growing well. It also held an unchanged bean and drawings with unanswered questions. “Shall we throw these pages away?” asked Coco. “They're what we really saw. Let's keep them.”
They tidied the work area and washed their hands. With the soil washed from their palms, they could add one last drawing without smudging the page.
Scene 10
A Garden with Room on the Page
The small pot found a bright place in Heart Garden. Coco opened the first page. They both smiled at “A forest tomorrow!” and its question mark. There was still no enormous forest on the last page.
Instead, there was a first root, newly opened leaves, and a day when they had chosen not to pour more water. Coco pointed to the water, root, and leaf drawings in turn. Mimi turned back a page so they could examine something they remembered differently.
“Have we finished the book?” Coco asked. Mimi pointed to the last empty space. “We've finished what we saw today.” Coco tucked the pencil inside the notebook instead of leaving it beside the pot. Tomorrow's shape was something to visit tomorrow.
