Sixth-grader Ryan Muhlenkamp closely analyzes the amount of water he and Jacob Sealscott, at right, squeezed into a graduated cylinder during an engineering experiment the students participated in recently at St. Henry Middle School. The students were asked to use a material similar to a frog's membrane (such as sponges) and develop an idea to keep it moist for a set period of time. The Project Lead the Way activity is designed to teach students the various steps necessary to work out a problem from start to finish.
