How Can You Estimate The Volume Of An Intact Sphere? Turn your frozen classroom into a geometric extravaganza! Students will take snowball engineering to a whole new level when they argue over how to determine the volume of the white orb. - In Cold Never Bothered Me Anyway, students brainstorm ways to determine the volume of a sphere that is whole. Let them work through this in small groups to see if any team can come up with the solution. Then, students will examine various snowballs, use given circumference measurement, determine the radius, and use the radius to estimate the volume of the sphere. - In Fixer Upper, students apply previous thinking and determine volumes of multi-sphered snowmen to determine which has the largest overall volume. - In You Wanna Build a Snowman?, (weather permitting) teams of students will be tasked to build a snowman. The challenge is to see which team can create the snowman with the largest estimated volume. (Use play dough if snow is scarce.)
