This week in Science we practiced identifying triangles and rectangles.
First, we remembered what a circle and a square looked like (from a few weeks ago).
Then we looked carefully at a triangle – it has three sides and this one is blue.
We tried making triangles with our fingers.
Then we looked carefully at a rectangle – it has four sides and this one is red.
We identified pictures of triangular
and rectangular items.
Then we explored a bin of triangular and rectangular objects.
Finally, we went on a shape hunt through the room to find triangles and rectangles.
Good job everyone!
Chag Sameach – see you next week,
We Sang “Apples and Honey for Rosh Hashanah”
We Danced Like Bees!
There were lots of apples
We heard the shofar
Went to Soergels
And of course baked…
What a wonderful time learning about Rosh Hashanah! Wishing you a happy and healthy New Year!
This week in Science, we compared and contrasted butterflies and moths.
First, we reviewed our caterpillar lesson from a few weeks ago. We picked out the two types we observed in class. (top left and bottom right)
Then we compared ourselves with an Eastern Tiger Swallowtail butterfly.
For example, we each have two eyes, two legs, no wings, use our nose for smelling and our tongue for tasting.
A butterfly has two eyes, six legs, four wings, smells with its antennae and tastes with its feet.
A butterfly also has a ‘proboscis’ – a sort of tongue / straw that it uses to drink nectar. The proboscis is curled up under the insect’s face:
Next we took a look at a Cecropia moth.
Again – two eyes, six legs, four wings, smells with its antennae and tastes with its feet.
…but the moth’s antennas don’t look at all like the butterfly’s.
How can we tell if a creature is a butterfly or a moth? We learned four differences between them.
(Note to email readers: There are hundreds of butterflies and thousands of moths in North America alone. The following distinctions are generally true, but many exceptions exist.)
Butterfly antennas have balls at the ends.
We could see the balls on the ends of the Pearl Crescent’s antennas:
Moth antennas are feathery.
Check out thisCecropia moth’s antennas!
2) Day or Night
Butterflies generally fly during the day.
Moths generally fly at night.
3) Wings at rest
Butterflies rest with their wings held upright. We tried doing that. It’s not very comfortable.
Moths rest with their wings folded over their backs
or stretched out flat.
4) Chrysalis or cocoon
Moth and butterfly caterpillars both hatch out of eggs, and their life cycles are very similar with one exception.
Before a caterpillar turns into a butterfly, it forms a chrysalis. A moth spins a cocoon.
Note: The Very Hungry Caterpillar book:
as cute as it is, is wrong on this point. Butterflies do not come out of cocoons – so either the cocoon in the story should be a chrysalis or the beautiful butterfly is really a beautiful moth.
Finally, we got a chance to compare a real cocoon and chrysalis.
A few weeks ago we observed some Milkweed Tussock Moth caterpillars at school. They looked like this:
The cocoon we looked at todaywas made by a Milkweed Tussock Moth caterpillar.
A few weeks ago we also observed a Monarch butterfly caterpillar. It looked like this:
A week later, when it was much larger, it climbed up the side of the jar and formed a chrysalis. We got to see the chrysalis in class today.
I’m hoping that a butterfly will emerge sometime next week.
Before we finished class, we also took a look at an old chrysalis – this is what is left after the butterfly emerges:
See you next week,
This week in Science, in honor of the letter ‘B,’ we learned about bird beaks.
First, we did the following activity:
We sat in groups of 4-5 around plates. Everyone got an empty blue container and a tool (either a spoon, clothespin, tweezers or tongs).
Then we had to use our tools to pick up sponges, straws, packing peanuts, and rocks off of the plates and put them in our containers. No hands allowed!
When we had picked everything off the plates,
we sorted our collected items onto graphing mats:
It turned out that the children with the tweezers or the tongs picked up the greatest number of items and the children who had the clothespins and spoons picked up the fewest.
Next, we read a book about beaks that explained that different types of birds have different types of beaks that are good for eating different types of food.
We tried making our arms into flamingo heads. They eat with their beaks upside-down!
We also made our fingers into crossbeak bills. They use their beaks to pry open pinecones.
Then, everyone got a picture of a bird.
We looked carefully at the beaks on our birds.
We matched the pictures with the type of food the birds eat.
They are all birds, but they have very different beaks to eat very different things!
Last, we reviewed our first activity – and matched our beaks with the ones in the pictures. (spoon = spoonbill, etc.)
The shape of each tool made it easier or more difficult to pick up each type of object – just like the shape of a bird’s beak makes it easier or more difficult to pick up different types of food.
Great job everybody!
See you next week,
This summer we have been traveling around the world! Our first three countries were Italy, South Africa, and Israel. (Click here to read about those weeks). Our next three countries were Russia, India, and China.
When we visited Russia, Morah Marina was our special teacher. She taught us Russian Words, about different kinds of Russian Food, and taught us special Russian Dances. She also told us Pushkin’s Folk Tale: The Fisherman and the Goldfish. Also thank you to Morah Nataly who brought in Russian Nesting Dolls and other fun items.
After Russia we traveled to India. Ms. Sandhya brought in Saris and other items from India and Milo’s grandfather read us Monkey: A Trickster Tale from India. We played with different spices, made Naan pizza, and made rangoli.
Then last week we went to China. Ms. Yann came in and made dragons with us and Ms. Diane danced with us and also taught us numbers in Chinese. We used different media to make Chinese symbols and also practiced using chopsticks!
This week we are traveling to Australia and next week to Brazil. We’ve been great travelers!
