Design Challenge: Tiny Titanic

The Problem: Design & construct a floating device that holds the most weight
Explore – What do we already know about this topic? / Specify Requirements
Criteria (wants): construct a floating device that holds the most pennies before leaking, sinking,or tipping
Constraints (needs):
  • Device cannot touch the container
  • Supplies:5 straws & 1 metermasking tape

Imagine – Brainstorm a few possible solutions. Can you develop at least three?
Develop a Solution– As a collaborative group, choose the best solution. Draw and label your plan below. / Why did you choose this solution? Be specific.
Create & Test Prototype– Raise your hand to receive supplies. Build and test your prototype. Obtain data and measurements. Explain your observations and findings, and consider sketching the finished prototype.
Evaluate Solution– Consider the results. Discuss or list the strengths & weaknesses of your initial prototype.
Strengths / Weaknesses
Develop a Redesign– What could you do differently to make an even more successful design? Discuss as a group and collaboratively choose the best option. Draw your new plan below and explain why you chose this redesign.
Drawing of Redesign / Explanation of Redesign
Create & Test Redesign – Raise your hand to receive NEW supplies to build and test the redesign. Obtain data and measurements. Explain your observations and findings, and consider sketching the finished prototype.
Evaluate Redesign– Consider the results. Discuss or list the strengths & weaknesses of your redesign.
Strengths / Weaknesses
Develop Final Design – This is it! Time to create a final design to share with the class. Are you going to modify your previous two builds or create a brand new design (risky!)? Discuss your ideas as a group, thenchoose the best option.
Drawing of Final Design / Explanation of Final Design
Create & Test Final Design– Raise your hand to receive NEW supplies to build your FINAL design. Do NOT test this one at your station; wait for teacher directions as you’ll be testing this design in front of the class.Obtain data and measurements. Explain your observations and findings, and consider sketching the finished prototype.
Evaluate Final Design– Consider the results. Discuss or list the strengths & weaknesses of your redesign. How did your final design compare to your other prototypes? How did your design compare to the winning design(s)? How did it compare to the losing design(s)?
