岩石的种类
Types of Rock
了解三种主要岩石类型：火成岩（由熔岩或岩浆冷却形成）、沉积岩（由一层层物质堆积挤压形成）和变质岩；并知道化石存在于沉积岩中。
Know the three main types of rock — igneous (formed when lava or magma cools), sedimentary (formed from layers pressed together), and metamorphic — and that fossils are found in sedimentary rock
学习证据 / Evidence
- 说出三种主要岩石类型：火成岩、沉积岩、变质岩
- 解释火成岩是由熔岩或岩浆冷却变硬形成的
- 说明化石保存在沉积岩中，因为沉积岩是一层层堆积形成的
- Name the three main rock types: igneous, sedimentary, metamorphic
- Explain that igneous rock forms when lava or magma cools and hardens
- State that fossils are preserved in sedimentary rock because it forms in layers
评估问题 / Assessment
如果{{name}}在海滩散步时捡到不同的岩石，他们能进行分类，并说明有些岩石是由冷却的熔岩形成的，有些是由一层层物质长期挤压形成的，还能说出化石是在成层的岩石中发现的吗？
If {{name}} finds different rocks on a beach walk, can they sort them and explain that some formed from cooled lava, some from layers pressed together over time, and that fossils are found in the layered ones?
