Help your students build real understanding of chemical formulas as models through ninety questions that move from basic recognition to genuine reasoning about how science works.
The set includes questions like "What do the elements in the formula MgO represent?", "In the formula CaCl₂, how many chlorine atoms are there?", and "Which of the following formulas represents a substance with 3 oxygen atoms?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a standards aligned science unit. The unit also covers Parts of an Atom and Their Roles, Atomic Particles by Charge, What Makes One Element Different, Similarities Within an Element, Reading and Writing Chemical Symbols, and Symbols to Communicate Element, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6 science classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard 6.5.e.
