Unit Overview

In Mosa Mack’s Design Thinking unit, students discover the steps of the Design Thinking process, and then use that process to design and build a product to rescue a stranded sloth.

  • Lesson 1
    Lesson 1: Design Thinking Mystery: A Stranded Sloth!

    Design Thinking Mystery: A Stranded Sloth!

    In the solve, students discover that problem-solving is a process that involves brainstorming, prototyping, testing, refining designs and retesting. (40 mins)

  • Lesson 2
    Lesson 2: Build a Tower & Discover the Design Thinking Process

    Build a Tower & Discover the Design Thinking Process

    Students will experience Design Thinking through the creation of a rescue tower challenge. They will create a reference booklet based on their reflection. The optional extension provides students with the opportunity to analyze famous engineering designs. (150 mins)

  • Lesson 3
    Lesson 3: Engineering Challenge! What will you build to save a sloth from a pit of hungry gators?

    Engineering Challenge! What will you build to save a sloth from a pit of hungry gators?

    Students will use the design process to plan and test a solution in order to save a sloth, Dullis, from the tree. Students will use their solution to write a final page of the story from lesson 1. (160-170 mins)

    Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
  • Inquiry Scale
    • Each lesson in the unit has an Inquiry Scale that provides directions on how to implement the lesson at the level that works best for you and your students.
    • “Level 1” is the most teacher-driven, and recommended for students in 4th-5th grades. “Level 4” is the most student-driven, and recommended for students in 7th-8th grades.
    • For differentiation within the same grade or class, use different inquiry levels for different groups of students who may require additional support or an extra challenge.
  • Common Misconceptions
    • Students may not realize that prototypes need to use proper proportions and should be designed from similar materials to that of the actual engineered product to test efficiency of materials.
    • Students may believe that Design Thinking is only used by engineers, but in fact this process is used in many areas and across many industries.
    • Learners may believe that since the steps of Design Thinking are presented in a specific order they must always follow them exactly as shown. Reinforce to students that Design Thinking is a creative process that may take different paths.
    • Students may initially think that a prototype should only be tested once. Emphasize to students that prototypes typically need to be tested and the design needs to be refined and retested a number of times before a final engineered product is produced. Through multiple tests, multiple variables can be identified and tested to make a more successful product.
    • Learners may be inclined to go with the first idea they come up with. Reinforce that brainstorming is a very important component to the process, and encourage students to be open to many ideas.
