不见的地图

Mira carried a map to the school treasure hunt. When her team reached the gate, the map was gone. She almost blamed Theo, who had carried the bag. Then she remembered taking the map out beside the fountain. "Let’s check there first," she said. Theo came with her. The map lay under a dry bench, where Mira had left it while tying her shoe. Mira thanked Theo and admitted her mistake. Back at the gate, she clipped the map to the bag. Her team followed the first clue together.

纸桥测试

虚构的练习数据或情境，并非真实研究报告。

In one invented classroom test, students compared a flat paper bridge with an accordion-folded bridge. They used sheets of the same size and paper type. Each sheet rested across the same gap between two books. Students added identical blocks one at a time until each bridge could not support another block. The flat bridge supported one block; the folded bridge supported four. The class recorded only one trial of each design. They wrote a conclusion about this test and planned to repeat it before making a broader claim.
