## Snowflake Modeling

Source: Bentley Snowflake

Type: Investigation

Theme: Nature

Grades: 5, 6, 7, 8, 9, 10

Learning Target: Students will model snowflake formation using multiple media types.

Instructions

For this investigation each student group will:

1. Choose two of the following methods to model snowflakes:

1. Paper folding and cutting

2. Desmos Calculator model

3. Desmos Geometry model

5. Geogebra model

6. An animation of falling snow

7. Coding method of your choice

2. Investigation will include:

1. A PowerPoint project.

2. Two six-sided snowflake models (see options above).

3. One well-written paragraph describing how your model patterns after nature.

4. A list of resources.

3. Select a partner for your group. You may work independently.
