On a recent sunny afternoon, Liberty second grade students went to the surface of the moon. Actually, it was about 20 pounds of flour in a wading pool outside their classrooms, but it served as a realistic substitute for a lesson involving the study of science concepts, integrated with a writing component. The lesson, developed by Liberty second grade teachers Amy Moore and Jana Pierce, was created using a STEAM approach, which uses cross-curricular elements of science, technology, engineering, art, and math to help students problem solve. The problem the second grade students were to solve the other day? “Why do the craters on the moon stay the same?”
Students used the scientific method to develop a hypothesis and the wading pool and flour served as the testing ground. Students dropped various sized meteors (balls) and examined the resulting crater sizes and shapes. They then completed the experiment by summarizing the results and writing their concluding remarks. “They stay the same because there is no wind on the moon.” said Gigi from Mrs. Moore’s class. Austin from Mrs. Pierce’s class added that “the meteors crash down and push the moon in and they are too deep to fill”. The lesson will continue with an examination of the phases of the moon. Materials for that lesson include Oreo cookies, flashlights, paper cups, and small round balls. “I really like studying the moon”, said Sergio from Mrs. Pierce’s class. “It’s exciting and fun!”.
