Moon MunchiesA Standards-Based Elementary School UnitPhotographic Overview of UnitNote: The teacher should discuss the safety rules with the students. Students should weargoggles when using tools.Getting StartedIf there are a variety of plastic trays (“pots”), the teacher may wantstudents to decide which one they will use first, as the size of the “pots”may determine the size of student lunar growth chambers. The teachermay suggest that students measure their “pots” before beginning tobuild. This may all revolve around a question/answer session. (Questionssuch as: What must go inside your chamber? How will you determinehow wide and long you will make your chamber? What can you do to Girlmake sure your “pot” will fit inside your chamber? Which material doyou think you should purchase first? Why?) For the building process, students may chooseto work on the chambers first and then the watering systems or vice versa. The electricalsystems and their containers should be the final pieces that students construct. They willneed to determine the length of the wires and the placement of the lights once the chambershave been constructed. The pictures below are intended to assist the teacher, but they are notmeant to suggest a particular way that items should be built. (For example, some studentsmay choose to measure and cut their tubing first and then poke a hole in their container.)When building the watering systems, chambers and electrical systems, students should beallowed to explore the materials and put materials together as they see fit.1MoonMunchiesPhotographicOverview ofUnitWatering SystemStudents need to determine the best placement for their tubing. They need to rememberthat the water needs to soak into the soil so that all the seeds/plants can be watered. Oncestudents have determined the placement of the tubing, a hole should be made in each “pot”using a pair of scissors, hole puncher or hammer and nail.BoyElementary School; NASA Engineering Design Challenge: Moon MunchiesBoy
