Organized by Design
Design Brief

Challenge

Students are finding their lockers and desks a mess due to the unorganized clutter of school supplies. To
help organize the student body, design and build a container to store and organize supplies. Because the
need for such a product is so great, we will be looking to mass-produce the items at a later date. For this
reason, your product must be made with the materials available in our workroom and cost less than \$10.00.
Only one design will be chosen for manufacturing, so the product should have at least three organizational
features that are sturdy and securely attached.

Criteria

Use only materials and tools available in the workroom.
Spend less than \$10.00 for materials.
Build at least three features that are sturdy and securely attached to organize supplies.

Problem Solving Design Loop Procedure
1.   Brainstorm ideas for containers and features. List all the ideas generated on your Design Loop Journal
Page. Choose a design and draw a scale model of it with a ratio of 1:2 on graph paper.
2.   Build the container your group chooses making sure it meets the guidelines.
3.   Test your container using the criteria.
4.   Redesign, making improvements and additions to the design. Retest using the criteria.
5.   Clean up your area and prepare to present your product and its features to the class.
