Help your students build real understanding of conservation in reactions through ninety questions that move from basic recognition to genuine reasoning about physics concepts.
Students will answer questions such as "Which diagram best represents a balanced chemical reaction?", "In a closed system, if 50 grams of A react with 50 grams of B, what is the mass of products formed?", and "What is the role of coefficients in a chemical equation?"
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 complete physics unit. The unit also covers Chemical and Physical Changes, Indicators of Reactions, Simple Reactions Lab, Reaction Types Overview, Endothermic and Exothermic, and Real World Chemical 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.
