Description

The Law of Conservation of Matter: Students will make a model to demonstrate that the total number of atoms does not change in a chemical reaction and matter is conserved. Students will learn about the conservation of mass and matter through hands-on science investigations, developing and using models and follow-up pages. Students will learn to count atoms. They will also learn that the same number and type of atoms in the reactants are found in the product, although they might be rearranged.

This resource includes a slide show, two labs, a hands-on activity making a physical model, an informational text article, response pages, and a quiz.

Science Standards Addressed in this Unit:

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 Standard 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)

Note to Teacher: My resources, including the slide show, are not editable. They are secure for copyright reasons.

The focus of this unit is on the introduction to the concept of the Law of Conservation of Mass. The words: mass and matter are both used in this lesson and in the scientific community when talking about this law.

The labs use simple materials: vinegar, powdered drink mix, baking soda, water, balloon, and a scale that can measure in grams. You will also need some plastic building blocks for the hands-on physical model

I am so impressed with this unit which manages to be distance learning and hands-on at the same time.  Really well thought out and engaging activities that allow students to practice each of the eight Science and Engineering Practices.  Really no prep for me!

The elephant article was excellent but I also thought the lab on dissecting a flower was broken down so easily, even telling me where to get inexpensive flowers!  This resource helped me teach this challenging standard in an engaging way.  Worth every penny!

My students loved this unit. I was able to present different elements of it throughout the month. It is hard to find interesting non-fictional, age-appropriate text for my students that they will enjoy. This was a great unit that aligned well for my students who have very different goals within the same group.
