Hide a bowl of ice or snow under a towel. Invite children to take turns placing one of their hands in the bowl and describe what they feel. Possible responses: It's cold! It's freezing!
Ask children what activities can be done in the winter but not in summer (skiing, sledding, ice skating, making a snowman, etc.). Discuss what is needed to be able to do these activities (snow and cold weather).
Explain to children that you are going to talk about snowflakes today. Ask, "Who likes to play in the snow? What is snow?" Ask children if they know how snow is made. Write their answers on the board. Explain that snow is frozen water. Snowflakes start as ice crystals that form in the cold clouds. Discuss that the temperature in the clouds needs to be cold (below 32 degrees). If it is not cold enough, rain will fall out of the clouds. When the crystals fall, they join up with other crystals to form a snowflake. The size of a snowflake depends on how many crystals hook together. This is why it is very difficult to find two snowflakes that are exactly alike.
Say, "Let’s read a book about snow to find out more about it." Read the book The Story of Snow the Science of Winter's Wonder.
Snowflakes form in clouds where the temperature is below freezing. The ice crystals form around tiny bits of dirt that have been carried up into the atmosphere by the wind. As the snow crystals grow, they become heavier and fall toward the ground.

Snowflake, snowflake, freeze my toes. (Touch toes.)
Snowflake, snowflake, swirl around. (Make spirals with hands and arms.)
Snowflake, snowflake, make no sound. (Put finger up to mouth to make quiet sign.)
Place a black piece of craft paper in the freezer. When it snows get children bundled up and take them outside. Have them take turns catching the snowflakes on the paper. Then, have them examine the snowflakes with a magnifying glass.
On a snowy day I like to . . . .
Provide children with a bowl of craft foam snowflakes and a sheet of light blue craft paper. Draw a large shape on the board (examples: triangle, line, plus sign, etc.). Let children copy the shape on the paper with the snowflakes. Repeat with different shapes.
Add real or instant snow to your sensory table.
