Help your students build real understanding of reaction energy changes through ninety questions that move from basic recognition to genuine reasoning about chemistry concepts.
Students will answer questions such as "Which example is NOT an endothermic process?", "Which of the following indicates an exothermic reaction?", and "Which of the following is an indicator of an exothermic reaction?"
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 NGSS aligned chemistry unit. The unit also covers Chemical Reactions, Types of Chemical Reactions, Balancing Equations, Identifying Chemical Reactions, Predicting Products, and Chemical and Physical Change, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 chemistry classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-PS1-2.
