Roland-Story students Jon Sobotka, Kari Stephens, Cleo Phelps and Killian Erickson were recently involved in an experiment to learn more about the topic of dew and frost — what they are and conditions needed to form. This activity required the students to develop their own experiment to demonstrate how and why dew and frost will form. The overall purpose of the assignment was to have students become more familiar with the concept of scientific proofs. Contributed photo
