This resource turns closed and open systems into a complete, ready to use review for Grade 6-8 physics, covering the same idea from three different angles.
Among the ninety questions, students will see prompts such as "What is crucial for a fair comparison between open and closed system experiments?", "In an open system, which scenario would likely lead to mass increase?", and "What would best demonstrate mass loss in an open system?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a NGSS aligned physics unit. The unit also covers Law of Conservation of Mass, 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.
