30个有趣的科学博览会项目创意，以添加到您的小学生名单中

科学博览会可能是小学生所爱的传统，并被父母深深地记住，但让我们面对现实：当您是老师时，请计划science公平是很多工作！您必须提出一份简单的科学博览会项目创意列表，以使您的学生入门，绘制出良好的科学博览会项目的组成部分，当然还计划博览会本身的所有元素。

The teachers on the Teach Starter team have been right where you are, Googling like mad for help to make the science fair a success for their students. Good news! We’ve put together science fair project ideas for 5th graders and 3rd graders (as well as a few other grades!), suggestions on how to throw a successful science fair in elementary school, and more tips to ignite purpose and possibility in your classroom!

是什么使一个好的科学博览会项目？

Before we dive into the best science fair project ideas, it seems wise to take a look at exactly what makes a good science fair project. Students may focus on the fun — and fun is a wonderful aspect of science — but you want them to actually learn something through experimentation!

一个好的科学博览会项目应遵循科学方法或使用engineering design process。学生可以从科学问题建立或确定他们打算解决的问题。无论哪种方式，该项目都应集中于结果或特定期望。提醒学生，一个好的科学博览会项目是一个实验，而不是演示！

您的学生科学博览会项目的组成部分可以包括：

1. A project title
2. A question that the project answers
3. 一个假设
4. 材料清单
5. An explanation of the experiment — what procedures were done to test the hypothesis?
6. 结果报告
7. Data analysis such as charts or graphs

科学Fair Project Ideas

您可以想象，“什么是一个好的科学博览会项目想法”的答案将大大变化，具体取决于您所教的成绩。有理由认为，三年级学生的科学博览会项目不会像六年级学生的科学博览会项目那样复杂。

The answer to this question will also depend on the units you’ve covered in class and students’ access to materials. It’s important to give students guidelines so the project is appropriate for their grade and skill level to ensure students are activating their knowledge, rather than getting frustrated with a project that’s well beyond grade level. It’s also helpful to provide a list as it limits students to projects you know are largely safe — ahem, no mixing dangerous chemicals — and allows you to set up parameters that keep the playing field equal among students of different socioeconomic backgrounds.

This list compiled by our Teach Starter teacher team is designed for use in elementary school or the lower middle school grades. Some of the science projects challenge students to test their understanding ofchemical reactions, others challenge students to use他们对能量的了解，同时更多地专注于研究水。每个人都有一些东西！
