Compare Test Results and Plan a Redesign
Written by Adi Ackerman, Head Teacher
"Compare Test Results and Plan a Redesign" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-ETS1-4. A 6th grader who is already steady on engineering and design can use it too, and an older student can use it as a short review.

7th grade science worksheet: compare three versions of a model bridge using load and sag data, then plan a redesign. Answer key included. Part of our design process collection. Aligned to NGSS standards.
How do I use this worksheet?
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.
What students will practice
- Students will compare how much load each version of a model bridge held.
- Students will tell what each change fixed and cite evidence from the table.
- Students will fill in tables with words and numbers and plan a redesign.

FAQ
How do I use this design process worksheet?
⌄
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.
What does this worksheet teach?
⌄
Compare three versions of a model bridge using load and sag data, then plan a redesign. The directions on the page read: Read about the bridge tests. Study the drawings and the table for use on page 2. An answer key is included.
Can I use this design process worksheet for homeschool or classroom?
⌄
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.
What is a need statement?
⌄
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.
How do you pick the best design?
⌄
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.
How do you use test data to redesign a model?
⌄
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.
