- the page has a title
- a toy car rolls too far past the stop line
For the problem "a toy car rolls too far past the stop line", which statement is the success criterion?
- stop near the line
- Ramp mat stopped the car closest to the line
- use a slightly rougher mat
Which constraint limits the design for "rainwater washes soil from a small garden slope"?
- Plan C kept the most soil in place
- add plants near the low edge
- do not block the walkway
Which test evidence should guide the design decision for "lunch cards blow away outside"?
- the best design has the brightest color
- use safe classroom materials
- Clip design held cards in light wind
What improvement best follows the evidence for "a toy car rolls too far past the stop line"?
- use a slightly rougher mat
- change the goal after testing
- ignore the test results
Which engineering problem needs a solution?
- the page has a title
- books keep sliding off a classroom shelf
- the table has a color
For the problem "rainwater washes soil from a small garden slope", which statement is the success criterion?
- use every material in the room
- Plan C kept the most soil in place
- slow the moving water
Which constraint limits the design for "lunch cards blow away outside"?
- make any solution with no limits
- use safe classroom materials
- keep cards on the table
Which test evidence should guide the design decision for "books keep sliding off a classroom shelf"?
- the best design has the brightest color
- Shelf B held ten books without bending
- books keep sliding off a classroom shelf
What improvement best follows the evidence for "a paper bridge sags under blocks"?
- change the goal after testing
- fold the paper into stronger beams
- remove the working part
