The Particle Model of Matter: Science Unit 1, Grade 8 (Letters & Devotion)

Description

The Particle Model of Matter is Unit 1 of Physical Science: Matter, Energy, and Interactions (Grade 8), the Letters & Devotion Science course, complete in one printable PDF: 12 lessons, the unit check-up and the answer key, 74 pages.

• Atoms and molecules as the building blocks of all matter
• Particle arrangement and motion in solids, liquids, and gases
• The relationship between particle spacing/motion and macroscopic state behavior
• Density as mass per unit volume, linked to particle spacing
• Density as evidence for distinguishing substances that look alike
• Temperature as average particle kinetic motion
• Conservation of particle number during phase change
• Conservation of particle number applied to an untaught phase-change context
• The distinction between phase change and chemical change at the particle level
• Generalization of the particle model to untaught states of matter
• Synthesis of particle spacing, motion, and conservation to explain a novel scenario
• Textual evidence supporting a scientific claim about phase change

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
