This comprehensive Middle School NGSS packet on Physical and Chemical Reactions is designed to align with the NGSS Middle School MS-PS1-2 and MS-PS1-5 standards. A visually interactive 50 slide powerpoint covers the main concepts in the standards "analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred" and "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". The physical and chemical properties of substances is covered as well as looking at everyday chemical interactions. Over 20 pages of student activities, questions and notes complete and compliment this engaging resource.
This is typically a topic that students find hard to grasp. I've designed this in simple incremental steps that builds upon previous knowledge that is sure to make this topic more engaging.
"Writing Curriculum this summer, what a great resource!" Maureen V.
PS1-A - Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.
PS1-B - Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. (MS-PS1-2),(MS-PS1-3),(MS-PS1-5)
The total number of each type of atom is conserved, and thus the mass does not change. (MS-PS1-5)
Acid/Base Neutralization Comic which are perfect for an INB.
