不是所有小虫子都是昆虫

不是所有小虫子都是昆虫：要区分昆虫和其他小虫子。蜘蛛有8条腿和2个身体部位（蛛形纲动物），潮虫有14条腿（甲壳纲动物），蚯蚓没有腿，蜗牛有壳和一只脚。还有“它是昆虫吗？”的分类游戏。

Not all minibeasts are insects: distinguishing insects from other minibeasts. Spiders have 8 legs and 2 body parts (arachnids), woodlice have 14 legs (crustaceans), worms have no legs, snails have a shell and one foot. The 'Is it an insect?' sorting game.

学习证据 / Evidence

• 能按照“有六条腿就是昆虫”的规则，把一组小虫子分成“昆虫”和“不是昆虫”两类
• 能通过指出蜘蛛有八条腿和两个身体部位，来解释蜘蛛不是昆虫
• 能说出昆虫和另一类小虫子之间的至少一个不同点，比如蚯蚓没有腿，或者潮虫有十四条腿

• Sort a set of minibeasts into 'insect' and 'not insect' groups using the six-legs rule
• Explain why a spider is not an insect by noting it has eight legs and two body parts
• Name at least one difference between insects and another minibeast group such as worms having no legs or woodlice having fourteen

评估问题 / Assessment

如果你拿一只蜘蛛给{{name}}看，并问{{name}}这是不是昆虫，{{name}}能解释为什么不是昆虫吗——比如说出蜘蛛有八条腿而不是六条？

If you showed {{name}} a spider and asked whether it's an insect, could they explain why not — for example, that spiders have eight legs, not six?
