### 4th Grade Next Generation Science Standards Learning Objectives & Essential Tools

Standards are often confused with being Learning Objectives. Standards are the content and skills students need to know by the end of a school year. Learning Objectives are the content and skills students need to know by the end of a lesson. Our Next Generation Science Standards Learning Objectives & Essential Tools guides display teachable Learning Objectives alongside the standards for easy reference. Here on Educeri, the guide also links to relevant lessons right here on the site, making finding a lesson easy. As we add more lessons, we will be updating this guide, so check back regularly.
