Phases of the Moon
All eight phases in order, from new moon to waning crescent, each with the correct lit side.

Layers of the Atmosphere
Earth's five atmospheric layers in order, from the troposphere up to the exosphere.

Types of Rocks
Igneous, sedimentary and metamorphic rock — what each looks like and how it forms.

Greenhouse Effect
How sunlight warms the Earth and greenhouse gases trap some of the heat.

Life Cycle of a Star
From a nebula to a main-sequence star, and the two paths for average and massive stars.
Physical Science 9
Matter and energy — the periodic table, states of matter and waves.

Periodic Table
A color-coded printable periodic table of all 118 elements — plus blank, with-names, and black & white versions.

States of Matter
Solid, liquid and gas — how the particles are arranged in each state.

Parts of a Wave
A labeled wave — crest, trough, wavelength, amplitude and rest position.

Atomic Structure
A labeled Bohr model — the nucleus of protons and neutrons, with electrons on their shells.

Magnetic Field
A bar magnet with its north and south poles and the curved field lines between them.

The seven bands from radio waves to gamma rays, in order, with the visible-light rainbow.

pH Scale
The 0–14 scale from acidic red to basic purple, with the neutral point at 7.

Parts of a Microscope
A labeled compound microscope — eyepiece, objective lenses, stage, focus knobs and more.

Forms of Energy
The eight forms of energy — mechanical, heat, light, sound, electrical, chemical, nuclear, gravitational.

Free, accurate, classroom-ready
Every science printable here is free, high-resolution, and made for the classroom. The periodic table is rendered from public-domain element data; the cell diagrams are clear, colorful labeled illustrations. Print them, hand them out, and teach.
This is a growing collection. More science printables — diagrams, charts, and reference sheets — are on the way.
