- In the classroom, Amir looks at a cup of juice and talks with a friend. He says the juice would spill if the cup had short sides. The cup has tall sides that go up high. Amir points to the sides and says, "These tall sides make walls." He adds, "The walls hold the juice in." Amir says, "That helps so it doesn't spill when I carry it." He walks the cup to the sink carefully. His friend says, "So the sides are like a fence." According to Amir, what do the tall sides do?
- In the hallway, the class takes a long time to line up for lunch. Maya and Amir want to change this. They use a timer to see how long lining up takes each day, and they make a chart of where the line gets stuck (by the door or by the cubbies). They also count how many reminders the teacher gives. They learn when it takes the longest and where it slows down. What information did they collect?

- In the cafeteria, Amir and Maya watch kids carry lunch trays. They ask, "What is hard about trays?" Three kids say, "My tray is too heavy," and one says, "My milk spills." The teacher helps them count, and they see 5 spills in one lunch. Amir says, "Spills happen when trays tip." Maya defines it: "The problem is that lunch trays are too heavy and tip for small hands." They think an improved tray or holder could help. What problem did they define?
