1. How many different shapes of snowflakes are represented on the chart?
The shape of a snowflake is determined by what TWO conditions?
2. What conditions form the largest, prettiest snowflakes?
3. Very cold dry air, like that found in Antarctica will produce what type of snowflakes?
4. Which snowflake shape is able to form at temperatures ranging from just below freezing
to 25 degrees below zero, yet only at low humidity?
5. Make a general statement about the relationship between snowflake size and humidity.
6. At what temperature range do dendrites form?

Answer the “myths” below.
Why do snow crystals have six arms, not 5 or 8?
Why is snow white?
Is it ever too cold to snow?
Is it really true that no two snowflakes are alike?
Are snowflakes perfectly symmetrical?
Do different shaped snowflakes fall in different locations?
Are snowflakes frozen raindrops?
What are rime and hoarfrost?
How many types of snowflakes are there?
When a snowflake melts and refreezes does it make the same shape?
In the section titled “Snowflake Primer”, summarize the Life of a Snowflake in your own words.
