解读恐龙足迹

利用恐龙足迹（化石脚印）来推断恐龙的大小、速度和行为——间距宽的脚印表示奔跑，间距窄的表示行走。

Use dinosaur trackways (fossilised footprints) to make inferences about a dinosaur's size, speed, and behaviour — widely spaced prints suggest running, closely spaced suggest walking

学习证据 / Evidence

• 解释较大的脚印通常意味着恐龙体型更大。
• 比较脚印之间的间距，推断恐龙是在行走还是奔跑。
• 推测一组平行的足迹可能意味着什么（例如恐龙成群结队地移动）。

• Explain that larger footprints generally mean a larger dinosaur
• Compare spacing between prints to infer walking versus running
• Suggest what a set of parallel trackways might mean (e.g. dinosaurs travelling in a group)

评估问题 / Assessment

如果{{name}}在博物馆看到一排恐龙脚印，能根据脚印之间的间距判断恐龙当时是在行走还是奔跑吗？

If {{name}} saw a line of dinosaur footprints at a museum, could they figure out whether the dinosaur was walking or running based on how far apart the prints are?
