Engineering Design Process (EDP): Mark the step that BEST matches each statement.

	Ask	Imagine/Research	Plan	Create/Test	Improve
Write the problem and success criteria
Brainstorm at least 3 launcher ideas
Make a labeled sketch and materials list
Build and run multiple launch trials
Redesign to fix what your data showed

In engineering, **criteria** are the you want to meet; **constraints** are the you must follow.

After your “pumpkin” leaves the launcher, which forces act on it while it is in the air?

Gravity and the launcher’s push

Gravity and air resistance

The launcher’s push and air resistance

Only the launcher’s push

Match each variable type to the BEST example for this launcher experiment.

Přetahovatelná položka		Odpovídající položka
Dependent variable		Pullback distance you choose
Controlled variable		Distance traveled (m)
Independent variable		Same projectile each trial
Controlled variable		Same launch line each trial

You want to test how projectile mass affects distance. Which plan BEST keeps the test fair?

Change only the mass and keep pullback distance and launch angle the same

Change the mass and also change the pullback distance each trial

Keep the mass the same and have different students launch each time

Change the mass and move the launch line closer or farther each trial

You want your launcher test to be a fair test. Which plan BEST supports a fair test?

Change the target distance each trial to see what happens

Let each group member launch however they want for creativity

Keep the same projectile and launch angle, and change only pullback distance

Change the pullback distance each trial and switch projectile types randomly

Based on your data, describe one redesign you made to improve distance or accuracy. Include: (1) what you changed, (2) what evidence from trials led you to that change, and (3) what you expected to happen after the redesign.

Which conclusion BEST uses evidence to justify a redesign decision?

We should redesign because our mean distance was low and our distances varied a lot across trials, so we will change one variable to improve consistency and distance.

We should redesign because our mean distance increased every single trial.

We should redesign because our launcher looked cool but felt weak.

We should redesign because another group said their launcher was better.
