Define Criteria and Constraints for a Design

Give the sheets in order, since each uses the thinking of the one before. Test Prototypes and Record Results and Compare Test Results and Plan a Redesign both use sample data, so no materials are needed.

Write a need statement for a flooding school garden, then sort criteria and constraints. The directions on the page read: Read the scenario and study the site sketch and limits box. Then write your need statement on the lines. An answer key is included.

Yes, both. We made it for 7th grade engineering and design, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

It is a short statement of the problem a design must solve. Define Criteria and Constraints for a Design asks students to write one for a school garden that floods.

Score each design on the same needs and add the points. Score Design Ideas With a Decision Matrix uses a score guide, then asks for a paragraph that recommends one design.

Compare the data from each version, find what each change fixed and plan what to change next. Compare Test Results and Plan a Redesign uses load and sag data for a model bridge.
