Conservation of Mass for Middle School Science

Do you need to introduce the conservation of mass to your middle school science students? 

Using this unit, students will learn about the conservation of mass and matter through hands-on science investigations and developing and using models.

This unit contains a variety of activities, including a PowerPoint slideshow with strategic note-taking guide, two labs, a hands-on activity making a physical model, an informational text article on the conservation of mass, response pages, a quiz, and answer keys for everything!

I am so glad to have this resource that focuses on conservation without requiring students to do more advanced work, like balance equations. Activities were good, especially the hands-on one with blocks.

This is a standards-based unit, covering NGSS MS-PS1-5 and Utah SEEd 8.1.6.

With one of my standards-based units, you can be sure you’re adressing everything that you need to cover!

NGSS MS-PS1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. 

Utah SEEd 8.1.6: Develop a model to describe how the total number of atoms does not change in a chemical reaction, indicating that matter is conserved. Emphasize demonstrations of an understanding of the law of conservation of matter. Balancing equations and stoichiometry will be learned at the high school level. (PS1.B)

My students loved the labs and I found the slide show and strategic note-taking guide super helpful. This author does such a great job aligning to standards. I have purchased several of Lynda’s resources and they are always terrific!
