by
:  Danielle Brown
Grade Level
: Elementary

Goal: To experience the shape and unique design of snowflakes 

Learning Objectives: Students will:
share what they already know about snow
formulate models by making their own snowflakes out of tissue paper
fold and cut paper equally so that they will be able to make six sided snowflakes
write about what will happen to their snowflake when it lands

NJ Science Standards: 5.8: All students will gain an understanding of the structure and behavior of matter, #2 Recognize that matter can exist as a solid, liquid, or gas and can be transformed by heating and cooling.

Materials/Resources:

Book to read: I am Snow by Judith Moffatt
Book to show: Snowflakes in Photographs, by W. Bentley
circle patterns for students to pace and cut
scissors
pieces of unlined white paper
lined paper for story writing

Procedure:
Introduction:

I will start the lesson with a question, “Does anyone know where snow comes from?’  Then I will read the story I Am Snow. Snowflakes all have 6 sides. I will explain that just like snowflakes humans are not the same; they are all unique. Before they go back to their desks to make their snowflakes, I will have them close their eyes and think of a place that their very own snowflake could land.  They will write about the journey of their snowflake.

Exploration:
Now the students will have to trace their own circles so they can make their own snowflakes or Stella’s friends.  Then they have to cut the circle as round as they can, and then they will fold them.  I will go step by step with them, so they don’t get confused.  When they have their snowflake, they will make a name for it. The procedure is as follows:

Fold perfect circle in half, then in 3rds, then in half again. Cut as many fancy designs as you can – the more cuts the prettier – but make sure the pieces stay connected. Cut the top curve down towards the point to get 6 arms. Cut the tip to get a hole in the middle. When you unfold it – you should have 6 sides each having the same pattern. Look for other patterns in your snowflake. A follow up lesson might include the reading of Snowflake Bentley (Caldecott Medal Book) by Jacqueline Briggs Martin, Mary Azarian (Illustrator).

Student Product: 
Application:
Write a story about what happens to your snowflake. Where does it land? What kind of adventure does it have? They must also include the name that they gave their snowflake and an illustration. Snowflakes can be hung on the window and stories on a bulletin board. Students should read their stories to their classmates.

Assessment:
Students need to know that snowflakes have 6 sides and pick up more crystals as they fall so they get bigger. In their journals they will answer these questions:

Snowflakes all have ____ sides.
Snowflakes are made of tiny _________ of ice.
When it gets too warm, the ice melts into ____________.
I like snow because_______________________…
 

Reflection:
I think that my lesson went pretty well. Asking them where they thought snow came from was good, because they all had different answers.  Then I started to read them the story. I included facts into the story and asked them questions as I went through it. When I was done I had them close their eyes and think of where their snowflake could fall, because they were now going to make their very own snowflake.  I was a little nervous for the folding of the snowflake, I wasn’t sure if everyone would understand. I had to help a few of the students out, but most of them were able to do it.  The cutting part was a little hard because their scissors didn’t cut very well. I was going to use tissue paper but I thought it would rip, but the duplicating paper worked. Then they named their snowflake, and one girl named hers after me!  I was surprised that they remembered what I had said in the story because most of the students wrote facts in their snowflake stories.
