Friday: Test Version 2

Rocket builds the new tower with a wide bottom row.

Four cups, then three, then two, then one.

Nova counts. "One, two, three... ten! It is still standing."

Raven measures with her ruler. "Let us compare it honestly."

"It is shorter," Rocket says. "But it stands!"

Compare honestly

Engineers tell the truth about results.

Version 2 stood for ten seconds.

But it was not as tall as a single stack.

Every design has trade offs.

READ THE RESULTS
  • Read the question.
  • Tap your answer.
Which version stood for ten seconds?
What one thing did Rocket change?
IdeaTrue or false?
Engineers tell the truth, even if version 2 is shorter.?
After Improve, engineers test again.?
If a tower falls, the engineer failed forever.?
WHY THIS EXERCISETesting and improving is how every good design grows.
Try it
Build your version 2.
Count to ten.
Measure it with a ruler.
Safety first
Build on the floor or a low table.
Do not stand on chairs.

Trade offs

A trade off means you gain one thing and give up another.

Version 2 gained strength.

It gave up some height.

Engineers choose what matters most for the goal.
