Activity Prep

Print Prep
In this lesson, students explore seasonal weather conditions across different regions. They investigate how weather patterns can be used to make predictions about future weather. In the activity, Snow Fort Weather, students organize daily temperature data from three snowy towns into a table so that they can compare weather conditions and predict which town is most likely to have the best weather for a snow fort festival next year.

Teacher Background

In this lesson, we discuss both the Celsius scale and Fahrenheit scale for measuring temperature. We mainly focus on Fahrenheit because students in the United States are more familiar with this temperature scale. We have Celsius worksheets available for the activity if you would like to use that temperature scale instead.
