Most of these science coloring pages can be re-created on a kitchen counter, which is the fun of the set. The volcano experiment bubbles over, a magnet lifts paperclips, a beaker fizzes next to its dropper, and test tubes wait in their rack.
The rest rounds out the lab. A microscope, a lab scale, safety goggles (color those first, it sets a good precedent), a lightbulb with idea-rays, and a solar system mobile with the planets strung in a row.
Everything downloads as a free US Letter PDF, A4 handled by Fit to page, and colors in the browser with progress on your device. A good pairing: color the volcano page, then do the baking-soda version for real. The page becomes the lab report.

Every magnet has two poles
North and south, always; snap a bar magnet in half and each piece grows its own pair. The Magnet and Paperclips page looks right with the classic red and silver horseshoe.

Eight planets, one easy mobile
Our solar system has eight planets, and the mobile page puts them on strings. Mercury gray, Venus cream, Earth blue-green, Mars rust, and the gas giants in soft bands make it read like the real lineup.

The lightbulb took thousands of tries
Edison and his team tested material after material before a filament lasted. The Lightbulb Idea page with its rays and stars is the right place to mention that ideas usually take more than one attempt.
