Engineering Design What is engineering? What are engineering jobs? Who can be an engineer?

Engineering Design Process • What is the Problem? Identify • What are the Rules? (Criteria/Constraints) • Explore the Materials Imagine • Brainstorm Ideas Plan • Think of an Idea to Share • Select a Group Idea • Gather Materials • Create your Idea Create • Test your Ideas • Look at the Score • Make the Design Better Improve • Repeat if Needed

Problem • Scenario: Jose loves to entertain his community by designing hay mazes every year. He needs some help this year in thinking of a new maze design. • Today, you will be putting on your engineering hat to build a maze! Identify • What is the Problem? • What are the Rules? (Criteria/Constraints)

Criteria: (Desired Outcomes) (Gr. K) Design a maze that: • is solvable • has all key elements drawn (connected walls, entrance, exit) • has only one entrance and exit • paths wide enough for a magnet to fit through • Bonus: Maze takes longer than 20 seconds to solve. • Bonus: Has barriers that stay up on their own Identify • What is the Problem? • What are the Rules? (Criteria/Constraints)

Criteria: (Desired Outcomes) (Gr. 1) Design a maze that: • is solvable • has barriers that stay up on their own • has only one entrance and exit • paths wide enough for a magnet to fit through • Bonus: Maze takes longer than 20 seconds to solve. • Bonus: Maze barriers are taller than 1” Identify • What is the Problem? • What are the Rules? (Criteria/Constraints)

Constraints: (Limitations) • • Time Limit: You will have 25 minutes to build the maze. Materials: You can only use the materials available. Cost: You will have 20 counters to complete this challenge. Collaboration: One design element from each team member must be used in the final design. • Redesign: Each team can test their prototype as many times as needed during the 25 -minute design phase. Identify • What is the Problem? • What are the Rules? (Criteria/Constraints)

Explore Materials Here are the materials we will be using. Can you classify them? What do they have in common? • • • Paper plate Chopsticks Marker Colored pencils Magnets Imagine • Explore the Materials • Brainstorm Ideas • • • Chenille stick Glue stick Scissors Construction paper Paper rolls

Brainstorm • 1 minute: Individual Design • Draw a plan of how you think Jose should design his maze and what materials would be used in the design. • 5 minutes: Each member presents their ideas to the group. • Share your ideas and focus on things you like the most about your idea that you would like to see be used as a design element for the final design. Imagine • Explore the Materials • Brainstorm Ideas

Plan Development (Gr. K) • Score card and criteria • Design a maze that: • is solvable • has all key elements drawn (connected walls, entrance, exit) • has only one entrance and exit • has paths wide enough for a magnet to fit through • Bonus: Maze takes longer than 20 seconds to solve • Bonus: Has barriers that stay up on their own • Select what materials will be used for the design Plan • Think of an Idea to Share • Select a Group Idea • Gather Materials

Plan Development (Gr. 1) • Score card and criteria • Design a maze that: • is solvable • has barriers that stay up on their own • has only one entrance and exit • has paths wide enough for a magnet to fit through • Bonus: Maze takes longer than 20 seconds to solve • Bonus: Maze barriers are taller than 1” • Select what materials will be used for the design Plan • Think of an Idea to Share • Select a Group Idea • Gather Materials

Team Member Responsibilities • Assign responsibilities of each team member during the process • Materials collector • Budget manager • Match the maze to the prototype Plan • Think of an Idea to Share • Select a Group Idea • Gather Materials

Test (Gr. K)

Test (Gr. 1)

Redesign: Discussion • What worked? • What didn’t work? • What do you want to improve? • Look at the Score • Make your Idea Better Improve • Repeat if Needed
