Our Fall inquiry started with many wonders. We wonder:
“Why do they (leaves) change from green?”
“Do leaves change every season?”
“Why do the leaves fall down?”
“Why do the leaves change colour?”
“How does it get colder?”
“Why are the leaves red?”
On our nature walk we explored around Parkcrest Park and looked for different kinds of leaves. We sorted them into Fall colours (brown, yellow, red, orange) and green and then tried rubbing leaves on paper to see if they leave a colour. We were pretty amazed to see nature colours on our paper!
We worked as a team and sorted leaves into different sizes- small, medium, big, biggest.
As scientists, we investigated why leaves change colours in the fall. First, we made some guesses.
“The weather is cold.”
“We have less sun.”
“It rains a lot.”
Then, we sorted the fall leaves by colour, ripped the leaves into bits and covered it with rubbing alcohol. We put coffee filters into the leaf and rubbing alcohol mixture and allowed it to sit long enough to absorb the liquid. As the liquid travels up the coffee filter it separates all the colors that were inside the leaf.
We learned that during fall, the days get shorter so the leaves don’t get enough sunlight and the green chlorophyll disappears from the leaves. As the green fades away, we begin to see yellow, orange, red and/or brown colours. Small amounts of these colors have been in the leaves all along!

Our Leaf People
The Leaf Man goes where the wind blows…
Our Leaf People flew to a lot of places and saw many things. Some flew to a pumpkin patch, some went to a forest, one went to a big city, a couple went to a farm and a few flew home. Please ask your child to tell you their Leaf Man story 🙂
