"I just got a text from NASA.
There's a Mars rover that's driving,
is stuck at a canyon.
We have to build and design something
that can transport a round object
that looks similar to our mini basketball here.
From one surface, in our case a table,
to another surface without any human intervention,
meaning you can't touch it,
you can't kick it, blow it.
You are the experts.
I need you to tell me how you can make that work."
What as Lehman frames the engineering design challenge
as a real world problem for youth to solve.
Listen to the constraints of the challenge
and notice how lemon moves youth
through the engineering design process
as they design something to move the object
from one surface to the other
without human intervention.
"Can we like put it on the top to go down?"
"Okay, that was a good question.
Everybody listen up.
Can you put the object onto your device
or whatever you are making?
Yes, you can start a process."
"I need at least one person from each team
to draw a design sketch.
Excellent, they have already started their sketch."
"Yeah we should put the box..." >> "We can..."
"How you're gonna
or where you gonna place it on the box?
I guess that is a better question.
Like you're gonna make a flat surface.
Okay, and just set it on the top?
"Yes." "Excellent idea.
Who's ready to build?"
"All our teams are ready to build.
We are gonna use cardboard
and not just any cardboard though.
This is space cardboard
meaning is very, very expensive.
You'll only get a little bit,
so you gotta make it count."
"You have to use what we have, right?
make it work.
Be mindful how you are releasing your rover."
"Alright, our original plan was
that all this like will stay up,
so that when we put the ball,
it'll roll down like this."
"Alright, let's see in action.
"Oh!"
"It's frozen." "Give it another try."
"Give it little bit fire."
"Oh!"
"Oh!"
"That was a valid effort.
That was actually a very good design.
If you had more time and more materials,
what would you do complete your project?"
Yeah, cause the tape, it dries out like
when you leave it in air."
"Yes, so we noticed that the tape dries up.
Your design, it works.
You just need to secure
some of those connections, I think, right,
if you have some more time."
"Let's pipe it out for this good guy here.
Good job."
