3rd Grade Writing Science Explanations

3rd Grade Writing Science Explanations Worksheet (Explaining with Evidence, TEKS 3.3B)

Students read shadow length data from one sunny day, find when the shadow was shortest, then use a word bank to finish scaffolded sentence frames like The data tells me and I noticed that. Simple black and white doodles and big, easy to read text keep the focus on the thinking, not the reading. No prior knowledge is needed: the page teaches the idea first.

What's Inside

• A teach strip with four science sentence frames
• Part A: read shadow lengths at 9:00, 12:00, and 3:00 and circle answers
• Part B: write words from a word bank to finish four sentence frames, with one done
• 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 writing explanations with sentence frames, part of the grade 3 scientific and engineering practices.

Why It Works

Each sheet teaches one idea first and uses simple sentence frames, so writing never gets in the way of the science. Every activity has a done for you example, and students only circle, sort, or write a letter, so they can finish on their own. Wrong choices are believable, not silly, so students have to think. Pair it with the other Explaining with Evidence sheets to cover claims and evidence, explanations, solutions, sharing findings, writing with sentence frames, and science talks.
