Is a spider an insect?

Teams sort sixteen animal clue cards into groups using features, not looks: backbone or no backbone, then fish, amphibians, reptiles, birds and mammals, then insects, spiders and others. They test the tricky cards (a bat, a dolphin, a penguin, a platypus) and build a yes-or-no key.

Read this to the class:

In the schoolyard, Dalia found a small black creature with long legs on a web. "An insect!" she said. Her friend Kofi counted its legs and shook his head. "That's not an insect." They argued all the way to lunch. Someone has to settle it. A scientist would not argue about looks. She would check features. Your team's job: sort sixteen animals into groups using features, and find out where a spider belongs.

Teams of three, with three rotating jobs: Sorter (moves the cards), Checker (reads the clues aloud) and Recorder (writes each group name and its deciding clue).
