Gr. 7 Chemistry

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.
