Activity 01
Whole Class: Environmental Problem Brainstorm
Present a local issue like waterway pollution. Guide the class through Ask and Imagine stages by listing questions on the board and sketching ideas collectively. Transition to small groups for initial plans.
Explain each stage of the engineering design process.
Facilitation TipDuring the Environmental Problem Brainstorm, record all student ideas visibly so they see connections between different environmental challenges and engineering solutions.
What to look forProvide students with a scenario: 'Your school playground has too much litter.' Ask them to write down one question they would 'Ask' to understand the problem, one idea they would 'Imagine' for a solution, and one material they might use to 'Create' a prototype.

Activity 02
Small Groups: Prototype Build and Test
Groups use recycled materials to Create prototypes for their chosen solution, such as a litter trap. Test designs under simulated conditions like water flow, record failures, and discuss initial improvements.
Analyze how engineers use this process to solve real-world problems.
Facilitation TipFor Prototype Build and Test, limit material options to force creative problem-solving and avoid overwhelming students with choices.
What to look forAs students work on their design projects, circulate and ask probing questions. For example, 'What problem are you trying to solve with this design?', 'What is one constraint you are working with?', or 'How will you test if your prototype works?'

Activity 03
Pairs: Improve and Iterate
Pairs swap prototypes with another group, provide feedback, then revise based on tests. Repeat one iteration cycle and present final versions to the class.
Construct a flowchart illustrating the iterative nature of design.
Facilitation TipIn Improve and Iterate, provide sentence stems like 'When we tested, we noticed... so we will try...' to scaffold reflection.
What to look forAfter students have created a prototype, have them present it to a small group. Each group member should provide feedback using a simple checklist: Did the prototype address the problem? What is one thing that works well? What is one suggestion for improvement? The presenter should note the suggestions.

Activity 04
Individual: Flowchart Creation
Each student draws a personal flowchart of the process, including arrows showing loops from Improve back to Imagine or Plan. Share one key learning in a class gallery walk.
Explain each stage of the engineering design process.
Facilitation TipDuring Flowchart Creation, model how to use arrows and loops to show design cycles before students begin.
What to look forProvide students with a scenario: 'Your school playground has too much litter.' Ask them to write down one question they would 'Ask' to understand the problem, one idea they would 'Imagine' for a solution, and one material they might use to 'Create' a prototype.

Generate Complete Lesson→A few notes on teaching this unit
Teach this topic by modeling your own design process out loud. Think aloud as you ask questions, sketch ideas, and consider trade-offs so students see the messy, non-linear reality. Avoid rushing students past the 'Improve' stage, as this is where critical learning happens. Research shows that students retain design thinking best when they experience failure as a natural part of the process, so normalize setbacks by celebrating them as discoveries.
Successful learning looks like students confidently shifting between steps, not just completing them in order. You will see groups testing prototypes, identifying flaws, and revising designs without prompting. Students should begin to articulate why iteration matters, using vocabulary like constraints, testing, and improvements during discussions.
Watch Out for These Misconceptions
During the Prototype Build and Test activity, watch for students assuming their first prototype should work perfectly.
After testing, ask each group to share what failed and why, then prompt them to map the failure back to their original plan. Use these shared examples to explicitly discuss the iterative nature of engineering.
During the Improve and Iterate activity, watch for students abandoning their initial ideas after the first test.
Require students to document each iteration with a brief explanation of what changed and why. This creates a record of learning that counters the idea of abandoning ideas prematurely.
During the Flowchart Creation activity, watch for students drawing only straight arrows without loops.
Display a sample flowchart with clear loops marked and labeled, then have students identify where their own designs required going back to previous steps. Use colored arrows to highlight iterations.
