Help your students build real understanding of law of conservation of mass through ninety questions that move from basic recognition to genuine reasoning about physics concepts.
The set includes questions like "Which of the following is a key concept in the law of conservation of mass?", "In a combustion reaction, what remains constant according to the conservation of mass?", and "How does the law of conservation of mass relate to chemical reactions?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned physics unit. The unit also covers Closed and Open Systems, Mass Measurement in Labs, Simple Equation Balancing, Lab Baking Soda and Vinegar, Particle Modeling for Mass, and Conservation in Physical Changes, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 physics classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-PS1-6.
