Egg Rescue Challenge

thingiverse

Students will apply problem-solving skills and engineering design process knowledge to create a device that meets the safety zone criteria and transports Eggbert Egg without further injury. I designed this by creating a solid piece with a copy made for each wall section. One copy becomes the hole, while the other forms the printable wall piece. To create hooks for holding the rod, I used cylinders with holes. Eggbert Egg's trouble is your problem to solve as part of a rescue team. He wandered off the trail and can't get up after falling. Your task is to design a 3D printable device using Tinkercad that safely transports the egg from one area to another without causing further injury. The device must be easily assembled and disassembled. Students will use their engineering design process skills to apply solutions within specified constraints. The attached design is an example device. Lesson Plan and Activity: Eggbert Egg has gotten into a heap of trouble by wandering off the trail during a hiking expedition and falling, unable to get up. As part of a rescue team, you must build a device that safely transports Eggbert back to safety without causing further injury. Students will use Tinkercad to design a 3D printable device that can be easily assembled and disassembled to safely transport an egg from one area to another. The student's design must: Include three or more interlocking pieces Be collapsible and able to fit in a ziploc sandwich bag Must be quickly and easily assembled Prevent the "victim" from rolling off and out of device Allow the victim to be scooped into the device without hands Must be lightweight, have low print time, or include non-printed materials (optional) Must be low-cost Students will start at Location A (Safe Zone) with their device completely disassembled in a ziploc sandwich bag. They will create a path around obstacles from one area of the room to Location B (Rescue site). At the Rescue site, students will assemble their device and transport the egg back to the Safe zone without touching it or causing damage. Teams will be timed from start to finish during the rescue. Duration of Lesson: 5 days (40-50 minutes/day) Preparation: Students should know the Engineering Design Process. Experience with Tinkercad would also be helpful but not necessary. If they do not have experience, add 40-60 minutes to the duration. Rubric and Assessment: Students will be evaluated on Teamwork, Meeting Design Criteria, Successful completion of the task. A grading rubric can be used. Objectives: Students will learn how to apply the engineering design process to successfully complete a task. Audience: Middle School Science This lesson is suitable for grades 6-8 but could be modified for lower or higher grades. Subjects: Middle School Science This lesson could be used in Science, Math, and/or STEM classes. Skills Learned: ETS1-1 Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions. ETS1-2 Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem. ETS1-3 Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success. ETS1-4 Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved. Common Core Math Standards 6.NS.C.6.C: Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane. 5.MD.A.1 Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real-world problems.
