As a snowflake falls from the sky, its crystal grows according to the humidity and temperatures of the air that it passes through. In this activity, students interpret a graphic that clarifies that growth and try to deduce what conditions…
In this activity students determine if this method for minimizing wrapping paper is actually more efficient then the traditional method. For a hands on learning experiment, have students actually wrap a small rectangular prism using any available paper in both the traditional and diagonal methods. Then let them compare the two quantities of wrapping paper and decide which method uses less paper and by what percent.
Students use the National Weather System chart to gauge wind chill, examine the patterns that correlate increasing wind and/or decreasing temperatures, use wind chill numbers to estimate possible wind and temperature factors, and generally become familiar with this sort of interpolation and calculation. There’s a great high school extention that uses fractional exponents and logs to solve.
