Sasha's Observations

The food is really piling up in the cup. The caterpillars are getting much longer and taller. They are most black and I see a white stripe on their backs. Their bellies are gray. It looks like they are really hairy. Their heads are black. I think they will make their cocoons next week. 

Juniper's Observations

I notice that their color is looking more gray. They have grown so much. I measured them with a ruler and they are over an inch long! It's funny that one of them is hanging and eating at the same time. They have eaten a lot of food, especially Twinkie. Their food looks different closeup than I thought it would. I thought it would look more like sand but it really looks like teeny white cocoa puffs. I think they will form their cocoons in four days!

Joel's Observations

The caterpillars are getting huge! I think they are about 1 inch each. A few of them are smaller than the others. There are webs all over the place. They are practicing to make their cocoons. The food is getting really crumbly and some of it is sticking to the webs and hanging off of the webs. The caterpillars are also shedding. There is also some poop in the cup. One caterpillar is climbing in a web and another is sleeping. Everything is good in the cups. 

Dylan's Observations

The caterpillars are getting fatter! They are making webs around the cup and their food is getting stuck in it. They are eating a lot of food. It looks like tiny dots and it is very crumbly. They are all different sizes but they are about a quarter of my finger. They are black and we can see their feet. It looks like they are shedding because I can see little black balls in the cup. 

Lucas' Observations

The caterpillars are spikey and cute. They like to climb. They have gotten a little bigger since we got them. They are moving and very slowly. I think that they are cool.

Henry's Observations

The caterpillars are very squirmy. Cookie Dough is busy eating. I think he is getting full. Another caterpillar (I think it is Candy), is fighting with another caterpillar. The caterpillars are as big as my fingernails. If you look very closely, you might see a little brown on them. I can see three of five legs. They also have spikey things on their backs. 

What an Awesome Surprise!

Since we still had many questions that were not answered from our story, we had to find a way to figure out the answers. We learned that two ways we can find out more information is to ask good questions and look up information in a nonfiction book or on the Internet. We also talked about observation and that we can look at and watch things to learn more information. We thought maybe we could convince Mrs. Friedrich to take us outside to look for some caterpillars, but she actually had a huge surprise for us! She got us 12 tiny caterpillars! Mrs. Friedrich said the caterpillars were delivered this morning. She thinks they are about 3 days old. They are really tiny. They are smaller than our fingernails! We names them Cookie, Coconut, Candy, Cookie Dough, Twinkie, Brownie, Lovey, Cutie, Tiny, Reese's Pieces, Smiley and Rufus! We are going to observe the caterpillars change into butterflies right in our classroom!

We talked about how this wasn't the natural habitat for the caterpillars, but it was ok because we were using the caterpillars to learn. We found out it would take almost a month for them to have a complete life cycle and become Painted Lady Butterflies. It is going to be really hard to be so patient… but Mrs. Friedrich knows we can do it! The caterpillars are in 2 containers. At the bottom of each container is food. The food is yellow. They are crawling all of over the containers. We are keeping them on the counter and 2 kids can observe them at a time, so we don’t scare them. We know to observe with our eyes, not our hands. We notice that they are black and have a lot of feet. They are also very fuzzy. Be sure to read everyday so you can observe the caterpillars along with us!

I'm a Caterpillar

During today's Community Read, we read I'm a Caterpillar, by Jean Marzollo. In this story, we learned about the transformations of a caterpillar to a butterfly. Caterpillars eat a lot of food and get bigger and bigger. When they are full, they hang from a stem and wait until they shed their skin. The soft skin that is left is called a pupa. The caterpillar then grows a hard shell to protect the pupa. The shell is called a chrysalis, or a cocoon. Inside the chrysalis, the caterpillar is changing into a beautiful butterfly! Once the wings dry off and unfold, the butterfly can fly. The butterfly visits lots of flowers and uses its long tongue to drink nectar. Butterflies aren't afraid of birds and birds aren't afraid of butterflies because they both think other one tastes awful! Soon, the butterflies will lay their eggs. The butterfly eggs have very thin shells. Caterpillars crawl out of them. Then, it starts all over again!

This story helped to answer some of the questions on our "What We Want to Learn" chart. We know more about how the caterpillars makes its own chrysalis and also about how much caterpillars eat.

We really enjoyed the rhyming sequence in this story. The illustrations by Judith Moffatt were also very beautiful. They were made out of different cut up pieces of paper. Mrs. Friedrich said we will be doing a project during Bonus Week where we will have to write our own poems and make the illustrations just like in this story. 

Becoming Good Scientists

Since we are learning to be good scientists, we made a KWL chart. This will help us sort out what we already know (K) about caterpillars and butterflies, what we want (W) to learn about caterpillars and butterflies and what we did learn (L) about caterpillars and butterflies.

This is what we already know about caterpillars and butterflies:

• Caterpillars make a chrysalis.
• Caterpillars turn into butterflies.
• There are many different types of butterflies.
• Some caterpillars eat their egg shells after they hatch.
• Butterfly wings can be very colorful.
• Butterfly wings are symmetrical.
• When a butterfly comes out of it's chrysalis, it's wings are wet.
• Butterflies live all over the world.
• Caterpillars find their own food.
• Some butterflies are poisonous.
• Some caterpillars are green.
• Caterpillars move by sliding and slithering.
• Caterpillars move very slowly.
• Some butterfly wings can be very surprising.
• Some butterflies are very pretty.
• Butterflies have 2 antennae.
• Caterpillars have legs.
• Caterpillars eat a lot.

We wrote our questions on post-it notes. This is what we want to learn about caterpillars and butterflies:

• Are caterpillars poisonous?
• How many years do caterpillars and butterflies live?
• How far do butterflies fly?

• Do butterflies drink nectar?

• How long does it take a caterpillar to change into a butterfly in a cocoon?
• How do butterflies have a baby?
• Can caterpillars eat insects?
• How do butterflies die?
• Do people or other animals hunt caterpillars and butterflies?
• Do caterpillars go underground?
• Can a caterpillar be a pet?
• How do caterpillars die?

• What do butterfly antennae do?
• Why are butterfly wings wet when they hatch?
• Do dogs eat caterpillars?
• Do caterpillars drink?
• Are butterflies nocturnal?
• How many eyes do butterflies have?
• How many types of butterflies are there?
• How many body parts are on a butterfly?
• How do butterflies find food?
• Where do butterflies lay their eggs?
• Do caterpillars make their own cocoons?
• Do butterflies have enemies?
• What do caterpillars hang onto when they make their cocoons?
• Do caterpillars have toes?

Changes in Nature

To start our unit on life cycles, we discussed the changes that we can observe in nature. Since we have been observing different things in the science center, and recently the flower experiment, we are used to making good predictions and observations. We also have been learning to keep science journals where we write down our observations and any questions we have.

We came up with a list of the changes that we can observe in nature:

• Leaves change colors.
• Leaves fall off trees.
• The weather changes. (rainy, sunny, cloudy, windy, snowy)
• Flowers and trees grow and die.
• The seasons change. (Winter, Spring, Summer, Fall)
• Animals and humans grow up.

In our long discussion about changes in nature, we talked a lot about animals that change, like tadpoles and caterpillars. We learned that these are called life cycles. It happens again and again, just like a circle goes around and around.
