Topic intro: Criteria and constraints
The topic opens on a scene and a question. It teaches nothing and coins no word; the lessons close the gap.

| # | Narration | On screen |
|---|---|---|
| 1 | Here's Mr. Park's class. Pencils roll off the desks all day long. | a classroom; one desk in front; two pencils roll off its edge and drop to the floor; no title slide |
| 2 | So Mr. Park sets a challenge: design a pencil holder for your desk. | Mr. Park, a whole figure with plain oblong arms, no fingers, at the front; speech chip DESIGN A PENCIL HOLDER |
| 3 | Erin builds a tall one with stars on it. Luis builds a short, plain one. | two holders side by side on a desk: Erin's tall and narrow with stars, Luis's short and wide and plain; chips IVY and LUIS under them |
| 4 | Someone bumps the desk. Erin's holder tips over. Luis's holder stays up. But Erin's used less cardboard, and it looks great. | the desk wobbles with short motion lines; Erin's holder tips and its pencils spill; Luis's stays upright |
| 5 | So which holder is better, and how would you decide before anyone starts arguing? | a question mark between the two holders |
| 6 | To find out, we will look at what a design must do, what it may use, and how to test it fairly. | the two holders stay; the question mark fades |
| 7 | Okay, so are you ready to find out how to tell if a design really works? | the three poll replies appear |
