是导体还是绝缘子？- 工作表

如果您在课堂上说“指挥”一词，那么您的学生可能首先认为您会深入研究有关火车的课程。

But as fun as it is to say “ALL ABOOOOARD!!”…

…在这项科学活动中，您的学生将试图预测通用材料的能量传递能力。

是导体还是绝缘子？

让电子自由移动的材料，允许转移热能称为导体。阻碍电子运动的材料，因此阻止能量传递称为绝缘体。

在这项活动中，学生将切断页面底部的对象，并将其分类为导体和绝缘体：

• Silver
• 玻璃
• 油
• 塑料
• 铜
• 橡皮
• 海水
• Gold
• Wood
• 钢

此资源也可以用作交互式笔记本活动。

Materials needed:

• 每个学生的工作表
• 剪刀
• Glue

此下载还包括一个快速分级的答案密钥。

与学生一起“进行”的其他活动

Don’t stop there! We’ve got a few other ideas for how to turn this exercise into more opportunities for independent practice and group learning:

Class Assessment

Curious to see what your students already know about conductors and insulators? Before teaching about the concept, have your students work on their科学调查和推理技能为了确定以前的这些材料的经验是否可以告诉他们材料的传导程度或隔热性。他们对不同的金属，木材，玻璃和其他人了解什么？完成课程测试后，他们通过要求学生再次作为退出票来学习。

小组课

Using your smartboard or another projection device, present the entire sheet so that your students can see both columns and the materials at the bottom of the page. Work through the material options together as a whole class, discussing the properties of the materials and writing your answers in the columns.

科学中心活动

No scissors, no glue, no problem! Create a reusable conductors and insulators activity by printing this resource on a single sheet of heavy cardstock to make it extra durable. Then, cut out the material cards to make them reusable game pieces. Put it all in a folder to keep the board and pieces together. You’ve just created a sustainable classroom activity that can be played again and again!

How to Prepare This Resource for Your Students

Because this download includes the answer sheet, we recommend first printing one copy of the entire file. Then, make photocopies of the blank worksheets for students to fill out on their own.

Students will also need glue and scissors to complete this worksheet. But they can also write the name of the material in the column instead.

If you plan to use this resource as a science center activity, we suggest printing on heavy cardstock for durability.
