Teach chemical reactions and the law of conservation of matter (AKA law of conservation of mass) using this presentation and the corresponding Cloze notes worksheet.
Students will be able to:
- Identify the reactants and products of chemical equations
- Identify that the arrow of a chemical equation means “yields”
- State the law of conservation of matter (law of conservation of mass)
- Analyze a reaction to see that the atoms present in the reactants are the same atoms in the products
Teacher Notes:
- INCLUDES AN ANSWER KEY.
- Related standards: NGSS MS-PS1-2 and MS-PS1-5
- Both the presentation (PPT and Google Slides) and Cloze notes worksheet (Word) are fully editable.

Related Standards:
- NGSS MS-PS1-2: Analyze and interpret data on the properties of substances before and after interaction to determine if a chemical reaction occurred.
- NGSS MS-PS1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
