Students will be asked to tackle a food system issue at home, at school, or in the community. This lesson will help you facilitate a structured design challenge in your classroom.
The goal of this lesson is for students to
Prep Time: 10 minutes
Activity Time: 60 minutes
This is the fifth and final activity in the Flipside Science: Our Hungry Planet unit designed for a middle school audience. In this lesson, students explore environmental issues related to the food we grow and eat with an emphasis on engineering and design thinking. Before implementing this design challenge in your classroom, it is recommended you start with the preceding activities in the unit:
If you are using this design challenge independently of the unit, your students can become more familiar with issues surrounding our global food system and some proposed solutions by watching the Our Hungry Planet videos.
‘Design thinking’ is a structured method that can be used to create a product, or to develop and implement solutions to a problem. Through the design thinking process, students can “learn to sharpen the focus of problems by precisely specifying criteria and constraints of successful solutions, taking into account not only what needs the problem is intended to meet, but also the larger context within which the problem is defined, including limits to possible solutions” (Engineering Design in the NGSS for Middle School).
The Design Challenge Levels outlined below are adapted from Design for Change’s design thinking toolkit. Each level can be printed off and given to students as a handout as they work through the challenge. Encourage students to keep track of their ideas and progress in a design notebook or on a blog.
Encourage your students to brainstorm together food system issues that they would feel empowered to tackle either at home, at school, or in their broader community. You can make this a whole class discussion, small group brainstorm, or individual homework. Check out examples of design challenge food topics on the Food Topic Design Challenge Spectrum that vary from one-day challenges to week-long challenges.
Students should work through the challenge in groups. Choosing a challenge that incorporates the whole class can not only help your students build teamwork skills, but can bring comradery to your classroom as your students empower not only each other, but youth outside of their own communities through the sharing of their designs.
Print out the following design thinking levels worksheet for your students.
Design Challenge Level 1: What do your students want to change?
Think about the different groups that your students are a part of: their family, their school, their city, their extracurricular clubs or sports teams, etc. Think about the food system issues that might be present in one of these groups. How healthy are the snack options in the school vending machine? Is there a lot of uneaten food that gets thrown away after dinner at home? How many vegetarian options are there for lunch in the school cafeteria?
Have students discuss the following issues with their group, and keep track of their progress in their design notebooks or on their design challenge blog.
Design Challenge Level 2: How can your students make a change?
In order to imagine change, your students need to brainstorm the possibilities. The possibilities multiply when they can brainstorm without constraints. Thinking outside of the box and sharing their ideas with each other can lead to highly successful and perhaps unforeseen solutions.
How do the students decide on a design? Have them discuss the following issues with their group, and keep track of their progress in their design notebooks or on their design challenge blog.
Design Challenge Level 3: Make the change!
Now it’s time for students to put their hard hats on! It’s time for them to get to work. Remind them why they have accepted this challenge! What is motivating to the students to design a solution? Who is going to benefit or be impacted by their solution? What do they need to take action? Discuss the following points with each group, and have them keep track of their progress in their design notebooks or on their design challenge blog.
Design Challenge Level 4: Share their experience
Congratulations to your students on completing their design! They should be proud of their accomplishment and want to share it with others. They should think about a time when someone else’s inspiring story has motivated them to take action. They will inspire others to make changes and design solutions by sharing their own experience!
How will they empower others? Have the students discuss the following points with their group, and keep track of their progress in their design notebooks or on their design challenge blog.
