We took a final look at our seeds today before inviting students to take their seeds home and plant them in their home gardens. Many of our final reflections continue to be about why some seeds grew and others did not. There was also some discussion about how seeds grow at different rates. Click here to listen to an audioboo from some of today's researchers. Ask your child to tell you what they learned about seeds from our experiment. Can they name the important parts? Can they tell you the 5 things plants need to grow?

We will continue to look closely at the concept of growing as we research our growing caterpillars, multiplying isopods and hopefully soon-to-hatching praying mantises. It will be an opportunity to strengthen our understanding of growing and what it means for the different plants and animals in our world.

May 7th - 9th
As our seeds continue to sprout and grow, we have been looking closely and comparing their growth. We noticed that most have shed their seed coat; this reminded us about how many of us have grown out of our own coats and shoes this year! We used uni-fix cubes to measure a sample of our growing seeds. Our research groups sorted the beans into two categories - short and long.
They represented the length as a number; our tallest bean was 17 cubes long and our shortest was one cube long. As the final step, students ordered the growing seeds from longest to shortest.
We noticed that the same conversation about length was happening in other parts of our classroom, with different living things. Students noticed our caterpillars are growing at different rates, our isopods have babies and youngsters of different sizes, and our potatoes are also growing shoots at different rates.

What do you notice about growing things where you live?

We read a book called "How a Seed Grows" to help us think a bit more about how our seeds are growing. We compared and contrasted what is happening in our classroom Seed Lab, with what happened in the book.
  • Megan - "Our seeds grow fast. I know because I see the stem popping up. Some have two leaves and some have one. Mine has two leaves."
  • Jordan "Our seeds are brown ovals. It grows fast. The seed's coat falls off and the green stem comes out."
  • Oskar: I don't think seeds are living because they don't move.
  • Oliver: I think seeds are living because when you give them water, they grow.

This led us to talk about the kinds of seeds we eat: Avery B (sunflower seeds), Kody (beans in soup), Oskar (the inside of a coconut), Anina (strawberry seeds - they are on the outside), Oliver (Tomato seeds), Owen (white watermelon seeds). We were stumped to come up with seeds we should not eat. Oskar thought we should not eat our bean seeds... Do you know?

We made some predictions about what we thought plants need: Oliver (water), Oskar (sun), Sheridan (dirt). We watched a video about the 5 things that plants need to help us build our understanding in this area. Ask your child to tell you what a plant needs to grow; how is it different from what we need to grow?

May 5th
As we get further away from our planting day, the differences between our seeds continues to grow. Some seeds remain dormant while others have rotted A handful of seeds have leaves! No one has quite decided what these seeds might turn into; our predictions continue to change daily. Our research group today wondered why some seeds grow faster than others. Riley sparked a conversation about how many different colours seeds could be. We knew that watermelon seeds were black and ours were brown, so we decided we are not growing watermelons in our classroom. We also continue to build and experiment using the new vocabulary we have learned. We are adding labels such as roots, shoots, sprouts, stems, and leaves to our diagrams now. We are also beginning to use comparative measurement terms such as shorter, taller, and fatter to describe what we notice about our growing seeds.

Here is a snapshot showing some of our growing seeds and ideas on Day 13 in their growth cycle:

Our research group had these thoughts to share:
  • Kody "I wonder why we have to have paper towels?"
  • Bridget "The been is growing!"
  • Jerahmeel "I see there is a little yellow in the middle of the seed."
  • Mia "I think it is growing into a flower with rainbow petals. I think the leaves will be purple though."
  • Riley "I wonder why the seed is brown? Watermelons have black seeds. Pumpkin seeds are grey."
  • Lilly "I wonder if my seed will grow? I think I see a sprout!!!"
  • Darla "My seed is a little bit shorter than my pencil."
  • Keria "My seed is as tall as my pinkie finger."

May 2nd
  • Jackson - "Why is my seed getting fatter?"
  • Kyhler - "It's growing. I see lots of roots growing out of it. The roots are white with a little brown and green on the outside."
  • Chase "I saw brown on it. It has a medium crack. I wonder if it might be a tulip?"
  • Ellissa - "It makes me think of a flower. It looks like a flower seed. Maybe a rose?"

When we looked closely at our seed lab today we were very EXCITED! Today's research group documented what they saw, thought, and wondered to share on our blog:
"The pod cracked!"
"Seeds grow. They need water, soil, and sunshine."

"It reminds me of my box growing flowers at home."
"I wonder why my paper towel is dry?"

In celebration of today being one of the the last days in National Poetry Month here in Canada, we learned a new poem about seeds. We created actions to go along with the poem. We drew a diagram of what our seed looked like today and drew a prediction of what we thought it might become in the future. Here is the poem we learned:

Little Brown Seeds (author unknown)

Little brown seeds so small and round,

Are sleeping quietly under ground.

Down come the raindrops

sprinkle, sprinkle, sprinkle.

Out comes the rainbow,

twinkle, twinkle, twinkle.

Little brown seeds way down below,

Up through the earth they grow, grow, grow.

Little green leaves come one by one.

They hold up their heads and look at the sun.

Today we noticed some big changes in our seeds! When today's research group sat and looked closely they thought:
  • Charlie: I noticed my seed is brown. I think it will turn white.
  • Devyn: My seed is almost about to bloom.
  • Breanne: I wonder why it is bigger? I think it is growing!
  • mallory: It was dark brown but now it's light brown. It used to be short but now it's big.
  • Adam: It looks like the beans I eat. It smells like them too. I think it will grow into a big bean!
  • Dylan: I wonder what the seed will grow into?
  • Bella: It feels wet on my paper towel.
  • Brixton: I see a swiggle.
  • Sierra: Why is there a little hole in the middle?


We noticed many students had questions and were not sure what to name the new growth they were noticing. We shared the following books to help us grow our vocabulary and developing understandings.

Do you have a favorite book about seeds and/or growing? We invite you to tweet us, or post in the comment section below, some of your favorite books!

When today's research group looked closely, their observations led them to draw detailed diagrams and ask some interesting questions:
  • Brooke: Why do we have to put a paper towel in the bag? I think if we took the paper towel out the seed won't open up.
  • Amaka: I wonder why there is yellow on the edges of the seed. It's changing colour; maybe it's starting to open up?
  • Breanna: I wonder why it changed from black to light brown. Why is the paper towel yellow now?
  • Philip: I wonder how seeds grow?
  • Anina: I wonder why there are lines on the seed? I think my seed will become a sunflower.
  • Beckham: I wonder why my seed shrinked?
  • Avery D.: I predict my seed will grow into a carrot.
  • Joey: There is one line on my bean.

Because we never quite know what the weather will be like here in Calgary, we have decided to start our seeds inside. Each day a group of scientists will be sharing what they see, think, and wonder about our seeds. Here is what today's scientists thought:

April 22nd
Today we started our seeds as one way to celebrate Earth Day! We spent some time looking closely and shared some of our initial thoughts:
  • Beckham – It’s dark brown.
  • Bridget – But it’s light brown inside
  • Dylan – There’s a white dot on the side.
  • Avery B – It feels hard.
  • Brixton – It’s kind of pointy on the top.
  • Lauren – It’s soft
  • Rania – It might grow into a straweberry plant.
  • Bella – Mine has a white line.
  • Kaitlynn – Mine is smooth.
  • Anina – It makes me think of chocolate because it’s brown too.
  • Sheridan - When it gets closer to the spot it gets blacker.
  • Joey – It’s shaped like an oval.
  • Alex R. – It reminds of the story Jack and the Beanstock!
