Solids, Liquids, and Gases PowerPoint

微软幻灯片软件, PDF|31页|等级：3-5

在向学生讲述固体，液体和气体时，将使用31张拼写的可编辑PowerPoint模板。

Use this teaching presentation when exploring物态和你的学生在一起。演示文稿还探讨了如何通过添加和删除来改变状态热.

本演讲中解决的一些关键概念包括：

物质状态的定义和示例（固体，液体，气体）
an explanation of how temperature changes can occur
explanations of how each change of state occurs
animated examples of various changes of state.

The presentation also includes links to a range of additional teaching resources that can be used to reinforce the students’ learning.

Note: This teaching presentation includes animations. To activate these functions on this PowerPoint, ensure that you have ‘Enabled Editing’ and are viewing the PowerPoint as a ‘Slide Show’.
