The activity limits teams to 100 cards and 2 feet of tape and allows about five minutes to build. Steps follow the engineering design process (Ask, Imagine, Plan, Create & Test, Improve) with prompts for constraints, stability, testing, measuring, and valuing failures through class discussion and notebook documentation.","Index card structure challenge – Basic Template  \n• The challenge: Can you build a stable structure using index cards, in order to display a small stuffed animal (or, hold a bag of beans or pennies)?  \n• The criteria:  \n-the structure must be as tall as possible  \n-it must be freestanding  \n-it must hold a small stuffed animal (or other objects such as a bag of 20 pennies)  \n• The constraints:  \n-you can only use 2 feet of tape, and up to 100 index cards per team  \n-you will have 5 minutes (adjust as appropriate for grade level, available time) to build  \nThis can be done as a “free build” activity, or extended into a formal lesson with time to discuss each of the steps and include writing/drawing in science notebooks and/or time for discussion with peers. Ideally this is done in groups of 2-4 students.  \nFor each of the “steps” of the engineering design process, some suggestions:  \nASK:  \n• This is when students are presented with a challenge:  \nCAN YOU BUILD AN INDEX CARD TOWER TO DISPLAY THE STUFFED ANIMAL?  \n• In the design process this is where a problem or challenge is identified by an engineer…  \n(e.g.“how can I make this   work better, more efficiently etc?” “How can I make this   stronger, taller, smaller?”)  \nIMAGINE:  \n• This is the brainstorming phase  \n• Independent brainstorming initially Encourage students to DRAW ideas!  \nThe pictures don’t have to look real, as long as they know what they mean…  \n• Use questions to prompt thinking:  \n-What are the constraints and criteria?  \n-What shapes are good for building?  \n-What designs might work? What won’t work?  \n-What kind of base will you use?  \n-How will you give your structure stability?  \nPLAN:  \n• Look at your brainstorm ideas and sketches.  \n• Which one seems like the best idea to try?  \nProvide productive discussion prompts for your students. Choosing between ideas and compromising can be difficult!  \n• Choose one idea, or synthesize multiple ideas  \n• How will you begin? How will you accomplish your goal within the constraints given?  \nCREATE & TEST:  \n• Build! Then, test. Adapt your building as you go. Measure your structure.  \n• Does your structure hold (the designated object)?  \n• What worked? What didn’t?  \n• Discuss successes and failures with the class –important to discuss the value of failure.  \nIMPROVE:  \n• What else could you try or do differently?  \n• Imagine, plan, and build a new structure, or adapt the structure you already built. Can you improve it?","cbCaijhlJKoAcpXL","https://ap.wps.com/l/cbCaijhlJKoAcpXL","pdf",381884,5,"English","en",105,"# Challenge Overview\n## Criteria and Constraints\n# Engineering Design Process Steps\n## ASK\n## IMAGINE\n## PLAN\n## CREATE & TEST\n## IMPROVE","[{\"question\":\"What are the main criteria for the index card structure?\",\"answer\":\"The structure must be as tall as possible, remain freestanding, and hold a small stuffed animal (or similar items like a bag of 20 pennies).\"},{\"question\":\"What constraints do students have during the challenge?\",\"answer\":\"Teams can use only 2 feet of tape and up to 100 index cards.
