The video tutorial explores the engineering process of solving problems by testing solutions. It emphasizes the importance of isolating variables to determine the effectiveness of a solution. Through experiments with a slingshot and a bowling game, the video demonstrates how changing one variable at a time helps in understanding the success of a solution. The criteria for success are defined, and the concept of variable isolation is explained. The video concludes by highlighting the importance of setting criteria and isolating variables in engineering problem-solving.

Describe the process of changing one variable at a time during trials.
