Someone asked how is it going to be night in India when it’s the day here.
“How do you know its night in India?”
“The sun moves in the night”
“Some places can be dark at the same time and light at the same time.”
“No! It’s because the sun can’t move to two places at once!”
“It’s not big enough to reach around”
“The sun is bigger than the earth”
“It’s so far away, it’s actually bigger”
We wonder: “Why do leaves change colors?”
“I know! They fall down to hibernate for the winter!”
“They change color so they can fall off!”
“Temperature. The snow is too cold for them.”
“Older trees don’t change color, young trees do.”
We ask: “Are you sure? Is it definitely true that older trees don’t change color? How do you know that?”
Some of us say there are trees that stay green forever. They are called evergreen. There’s a clue right in the name. So far we think you can tell them from the trees that change colors because they are darker green and they have a different shape.
These two videos tell the science about why leaves change colors:

We are called the Sycamore and Sassafras class this year. We go on a walk every day. We are learning the names of all of the trees! We study books to match the picture and the words. Trees tell you their name by their leaves and bark and branches. Can you tell what kind of trees these are just by reading their leaves?
Some people say trees are magic because they can change the colors of their leaves. Ms. Echternacht (Ek-ter-knocked) keeps looking at the leaves on the trees but so many still look green. Ms Cagney says, “be patient”. Do you think these leaves will change color?
One day, we found a “bouquet” of leaves on the ground. We asked, “Will this bouquet of leaves change color?” 4 people said, “YES!”, 12 people “weren’t sure” and 1 person said, “NO!”
The 4 people who said the bouquets of leaves would turn colors explained “all green leaves change colors.”
The 1 person who said no said she thought they “have to be attached to get food to grow and change.”
Some people started changing their minds. We are thinking to put the bouquets in cups of water and see if they will change now.
What do YOU think?
We walk everyday looking for evidence that green leaves will change colors. Nothing happened for a long time. Then one day….
Do all leaves change colors? How are trees doing this bit of magic? Can YOU change your colors? Why do you think trees do this? We are digging deeper everyday to discover the mysteries of trees.
We like these two songs about the Water Cycle! What do you know about the water cycle?
Mrs Cassidy is a first grade teacher in Canada. Canada is the neighbor of the United States. Look how fast our neighbors get ready for the snow- can YOU beat their time?
Last summer, Ms Echternacht (Ek-ter-knocked) went on an airplane to a teacher meeting in a place called Atlanta, Georgia. It’s hot and steamy there. It’s the place where Dr Martin Luther King, Jr. was born. One afternoon, Ms Echternacht rode the train to go see where Martin Luther King was born.
It was a long train ride. When Ms Echternacht got off the train, she was hot and tired. She looked around for a sign to show how to get to Dr. King’s house, but there were no signs. No one was even around. It was an empty part of town.
So, she started walking and hoping that she would see a sign soon, but there weren’t any. A Mom and her two little boys in bright red matching shorts were walking in front of her and Ms Echternacht heard them ask a man “Where is Dr. King’s house?”. The man she asked didn’t have very many teeth and at first, he did look a little scary, but he said, “This way, I’ll show you!” Ms. Echternacht said to the Mom, “I’m going there too!” So we all walked together.
The Mom and kids were from Chicago visiting their family and they really wanted to see where Dr. King lived. So did Ms Echternacht. We walked past the park and some empty stores. We walked past a big apartment building with lots of people sitting outside. They waved to us and the man with no teeth. It was where he lived. He told us “go left and go right and then a few more blocks and you’re there” and then told us goodbye. We said, ‘Thank you!” and waved back. We were so glad he showed us the way to get there!
Ms Echternacht and the Mom and her two boys with bright red shorts all went into the church together to see what it was like. Everyone sat down very quietly and said prayers.
Ms Echternacht could feel Martin in the church. When she was ready to go, she thought maybe the Mom and her two boys in matching shorts had already gone, but no! they were still there! We all went to the gift shop together. Ms Echternacht got her six year old nephew a bright yellow T-shirt that said “Ebenezer Baptist Church”.
Finally, we were ready to get to Martin’s house. It was just one block away! We were almost there! But when we got there, the house was closed. It had taken us so long to get there that we couldn’t go in! We were just happy to see his house though, and so the boys in the bright red matching shorts sat on the front steps of Dr. King’s house and we all took a picture.
We were getting tired, but there was still more to see! The big museum was just across the street and we wanted to see that too. Also the place where he was buried.
When Dr. King died, everyone was crying. Well, most everyone. The boss of Georgia did not want to give Dr King a big funeral. He wanted everyone to go away and forget about Martin. He thought Martin was bad. But everyone knew that Martin was good and everyone remembered him. They came from all over the world to march three and half miles and cry, sing and be very still and quiet for his funeral. People still cry today for Martin and teachers make sure to teach kids about him so no one will ever forget him.
We were all quiet for a long time. Then we went to the Museum. They had important things there from when Martin was alive.
Finally, we went across the street to the Dr King National Park.
After seeing all of this, Ms Echternacht and the Mom and her two boys with the matching red shorts were very tired, but very happy. We were all so glad that no one would ever forget about Dr King. Then we started the long walk back to the train together.
We were out playing and noticed the leaves were all over the ground! And they were different colors! Ms Echternacht couldn’t believe someone would tear all the leaves off the trees and paint them like that. What’s happened out there?!
Someone said “No, that’s supposed to happen! It’s fall. That’s what happens in the fall.”
Teacher: “But why?! Why now? Why do they fall off?! How is that even possible to change colors? Are trees magic?”
“No! No one painted them! They just change.”
“The wind blows and it makes the colors change”
“No! That doesn’t make sense because it was windy in the summertime too.”
“The colder it gets, the heavier the leaves get and they fall down.”
“The leaves are happy.”
“They change on the first day of fall.”
“Maybe it has to do with water.”
“They don’t fall! They connect down. When it’s not fall, they connect up.”
‘They are hanging there and they just can’t take it anymore and they fall off!”
Then someone noticed that the brown leaves were crinkly and fell apart easily and the green ones were harder to tear. We will continue digging into this science question!

Someone noticed that one of the triangles had two long sides and one short side. We labeled the sides “L” for “long” and “S” for “short”. Then someone noticed the rectangle had two long sides and two short sides. Then we wanted to know “how long” because math girls always dig deeper and know exactly “how long” or “how short”. We used a measuring stick to find out the numbers and then wrote that down. We then traced the lines of the shapes. See how our math conversation continues:
