Snowflakes can vary significantly in size and shape, often influenced by atmospheric conditions as they form. Each snowflake is unique, showcasing a fascinating array of structures due to the intricate process of crystallization that occurs as water vapor freezes in the atmosphere.

Spark you thinking!

1. Set up your science mini spark recording page: #16: Snowflakes

2. Watch this TED-Ed video. Take detailed notes on your recording sheet.

3. At this site you can see some snowflakes under a microscope and read about how snowflakes are formed. Record 5 things you learned on your recording page.

4. Create a script where you are interviewing a snowflake. Include 3 or 4 interview questions with the snowflake providing answers. You can use the questions ideas below as a guide or you can create your own.

• What initiates the formation of a snowflake and how does it evolve into a complete snowflake?
• Explain the process of crystallization and how it contributes to the symmetrical shape of a snowflake?
• Why do snowflakes have six sides?
• How does the temperature and humidity of the air influence the basic shape of an ice crystal?
• What are the types of ice crystals formed at different temperatures, and what conditions contribute to their formation?
• Describe how the atmospheric conditions encountered by an ice crystal affect the intricate shape and arms of a snowflake.
• How do the different paths from the sky to the ground influence the unique appearance of individual snowflakes?
• What are some of the diverse forms and patterns that individual snowflakes can resemble?
• In what ways do slight changes in the surrounding temperature or humidity impact the growth and direction of the arms of a snowflake?

5. Share your science mini spark recording page with your teacher/EY coordinator.
