3rd Grade Decomposition Makes Soil

3rd Grade Decomposition Makes Soil Worksheet (Earth and Space, TEKS 3.10B)

Students learn that decomposition breaks down dead plants and animals into humus with help from worms and fungi. They number the steps from fallen leaf to soil, then decide which statements are true. Simple black and white doodles and big, easy to read text keep the focus on the science, not the reading. No prior knowledge is needed: the page teaches the idea first.

What's Inside

• A teach strip on decomposition, worms, and fungi
• Part A: number the steps from a fallen leaf to rich soil, with one done
• Part B: circle True or False, including that decomposition does not break rocks
• A friendly squirrel guide that points out the key idea
• A visual answer key with answers marked in red, plus a short teacher note

How Teachers Use It

Use it as a mini lesson follow up, a quick check, or a science center. It takes 6 to 8 minutes and prints clearly in black and white. The focus skill is explaining how decomposition helps form soil, part of the grade 3 earth and space strand.

Why It Works

Each sheet teaches one idea with everyday objects kids already know. Every activity has a done for you example, and students only circle, sort, number, or write a letter or word, so they can finish on their own. Wrong choices are believable, not silly, so students have to think. Pair it with the other Earth and Space sheets to cover weather, how soil forms, landforms, and fast changes to Earth's surface.
