  1. The World of Snowflakes

  2. The Water Cycle

  3. The Water Cycle evaporation

  4. condensation The Water Cycle evaporation

  5. condensation The Water Cycle precipitation evaporation

  6. Snowflakes form at the condensation stage. The Water Cycle

  7. Snowflakes form at the condensation stage. The Water Cycle The water vapor condenses directly into ice!

  8. Snowflakes form at the condensation stage. The Water Cycle This process is called “sublimation.” The water vapor condenses directly into ice!

  9. Every snowflake starts out as the same basic shape.By the time each snowflake touches the ground, it isunique. Why?

  10. Weather conditions within the cloud...

  11. Weather conditions within the cloud... temperature

  12. Weather conditions within the cloud... temperature Temperature: the measurement of how hot or cold something is.

  13. Weather conditions within the cloud... humidity

  14. Weather conditions within the cloud... humidity Humidity: the amount of water vapor in the air.

  15. Conditions in the atmosphere as the snowflakes fall to the ground.

  16. Properties of a Snowflake

  17. Properties of a Snowflake • A snowflake is made of ice crystals.

  18. Properties of a Snowflake • A snowflake is made of ice crystals. • A snowflake is tiny.

  19. Properties of a Snowflake • A snowflake is made of ice crystals. • A snowflake is tiny.

  20. Properties of a Snowflake • A snowflake is made of ice crystals. • A snowflake is tiny. • A snowflake is symmetrical.

  21. Symmetry – Two Dimensional Polygons Key words:

  22. Symmetry – Two Dimensional Polygons Key words: A regular polygon is a polygon in which all sides are the same length.

  23. Symmetry – Two Dimensional Polygons Key words: A regular polygon is a polygon in which all sides are the same length. A line of symmetry for a polygon is any line on which the polygon can be folded so that one half of the polygon will fall exactly on the other half.

  24. How many lines of symmetry does Snowflake 1 have? __________ How many lines of symmetry does Snowflake 2 have? __________ What regular polygons are these snowflakes? __________________

  25. Properties of a Snowflake • A snowflake is made of ice crystals. • A snowflake is tiny. • A snowflake is symmetrical.

  26. Properties of a Snowflake • A snowflake is made of ice crystals. • A snowflake is tiny. • A snowflake is symmetrical. • A snowflake is 3 dimensional.
