Gr. 7 Chemistry
All of our Pure Substances & Mixtures unit resources will be posted here and broken down into 3 sub units; Classifying matter, Solutions, and Separating Mixtures. Any extras (Could do’s) are located at the bottom of the page.
Lesson 1: Classifying Matter
1.1 – What is Matter? (Make a copy of all student textbook pages and add them to your Chemistry Folder)
1.2 – More About Matter (After adding to your Chemistry folder, read and answer questions #1 -4)
Lesson 2: Pure Substances vs. Mixtures
1.4 – Pure Substances and Mixtures (Read and answer questions #1, 3, and 4)
Classifying Matter Quiz Study Sheet
Lesson 3: Heterogenous vs. Homogenous
1.6 – Mechanical Mixtures and Solutions (Read and answer questions #1, 2, and 5)
Lesson 4: The Periodic Table of Elements
Some Key Concepts About Elements and their Atoms
- Atoms are made of extremely tiny particles called protons, neutrons, and electrons.
- Protons and neutrons are in the center of the atom, making up the nucleus.
- Electrons surround the nucleus.
- Protons have a positive charge.
- Electrons have a negative charge.
- The charge on the proton and electron are exactly the same size but opposite.
- Neutrons have no charge.
- Since opposite charges attract, protons and electrons attract each other.
