5 Goals of Web Seminar: Snowflake taxonomy & classification IntroductionGoals of Web Seminar: Snowflake taxonomy & classificationMeet the scientists for The History of Winter:Dr. Peter WasilewskiEric ErbeScientist do some outrageous stuff!
12 Winter on other planets Ice Formation on Earth and Mars Solar System IceWinter on other planetsIce Formation on Earth and MarsIce Formation Demonstration
13 Solar System IceQuestion 1: Do you think you can have winter with ice on the lakes and snowflakes in the sky on all the other planets?YesNo
14 Question 2: How do you think winter will vary on Mars versus Earth? Solar System IceQuestion 2: How do you think winter will vary on Mars versus Earth?Ice will be colder on MarsIce will vary in color on planetsIce will vary in size on planetsIce will vary in shape on planetsIce will be made from different stuff
42 What affects snowflake formation? Question 12: Thinking back to the map of the US, what is different about each school location and how might this affect snowflake formation?
43 Graph analysis: Snowflake Formation NES Educators:Sue WhitesideLisa Stoner
44 Graph analysis: Snowflake Formation Question 13: Which factors might have the biggest impact on snowflake formation? A. Wind Speed B. Temperature C. Daytime/Nighttime D. Amount of water in air (humidity)
46 Today In ReviewIce and winter exist on other planets in the solar systemIce on other planets may be very different then water ice of EarthThere are different types of snowflakes on Earth that may be classified by a known taxonomyTwo main factors affect snowflake formation:Water content in air affects snowflake sizeTemperature of air determines snowflake type
