Chemical Reactions Mastery Bundle: Slides, interactive notebook and 40 mark test.

Transform your chemistry unit from “confusing formulas” into a hands-on exploration of the building blocks of the universe! This comprehensive bundle provides everything you need to teach Chemical vs. Physical Changes, Gas Tests, Word Equations, and the Law of Conservation of Mass.

Featuring a “Brick Balancing” activity and high-engagement lab observations, this bundle is designed to build a rock-solid foundation for middle school or introductory high school chemistry students.

What’s Inside?

1. Instructional Slideshow (PPTX)
   Visual Transitions: Clear distinctions between physical changes (reversible) and chemical changes (new substances).
2. Student Companion Notes (DOCX)
   Observation-Driven Learning: A structured lab log for students to record results from 5 different reactions (including heating sucrose and mixing magnesium with acid).
   Gas Test Toolkit: A handy reference table for identifying Hydrogen (“Squeaky Pop”), Oxygen (“Glowing Splint”), and Carbon Dioxide (“Limewater”).
   Scaffolded Practice: Exercises for identifying reactants vs. products and a dedicated “Balancing Equations” workspace with 10 increasingly difficult problems.
3. Comprehensive 40-Mark Unit Test (DOCX)

The “Steel Wool Practical” included in these notes is a game-changer for teaching the Law of Conservation of Mass. Seeing the mass increase on the scale usually confuses students—until they use the slideshow to realize they’ve actually “captured” oxygen from the air! It’s the ultimate “Aha!” moment.

Before you print- the mark scheme is included in the same document as the test (and yes I have printed and given out the test with the mark scheme to a whole class!)
