This resource includes a ready-to-use interactive version of the PDF. Assign it to students to complete from any device. Easel by TpT is free to use! Learn more.


This pdf packet contains 12 separate worksheets/quizzes and 4 labs encompassing synthesis, decomposition, single & double replacement, combustion reactions, and the law of conservation of mass. The worksheets range from a "first day" worksheet to advanced/honors work. Over 300 unique equations in all, plus questions that support students in understanding the concept of balancing equations and why it's important.

The "Easel Activity" has been created for you - every equation has the boxes for balancing included! With over 300 equations and an average of at least four answer boxes per equation, that over 1200 answer boxes you won't have to create!

All answer keys for worksheets and quizzes are included in the file.

The 4 labs cover conservation of mass, types of reactions, and factors that affect the rate of reactions.

This product is easily three weeks of work in your class - at least. Great on its own, and also a great resource for emergency sub plans for those days when you are out unexpectedly and can't make lesson plans.

The preview file is the full packet so that you can determine if this product meets your needs.

to see state-specific standards (only available in the US).
Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. Examples of chemical reactions could include the reaction of sodium and chlorine, of carbon and oxygen, or of carbon and hydrogen. Assessment is limited to chemical reactions involving main group elements and combustion reactions.
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. Emphasis is on using mathematical ideas to communicate the proportional relationships between masses of atoms in the reactants and the products, and the translation of these relationships to the macroscopic scale using the mole as the conversion from the atomic to the macroscopic scale. Emphasis is on assessing students’ use of mathematical thinking and not on memorization and rote application of problem-solving techniques. Assessment does not include complex chemical reactions.
