Which Explanation Is Stronger?

Which Explanation Is Stronger? Worksheet: Comparing explanations by their evidence (Grade 4 Science, TEKS 4.3C)

Students learn that a stronger explanation uses numbers someone can check, mark four soil drainage explanations as stronger or weaker, then read two speech bubbles about the same seed test and decide whose explanation is stronger and what would fix the other one. The page teaches the skill first, so no prior lesson is needed, and every student task is sort, circle, or fill in. One sheet is one page, with two short parts and nothing to write from scratch.

What's Inside

• A short teach box on what makes an explanation stronger
• Part A: write S (stronger) or W (weaker) for four explanations, first one done
• Part B: three circle the answer questions, first one done
• A visual answer key with answers marked in red, plus a short teacher note with what to watch for

How Teachers Use It

Each sheet follows the same three steps: read the short teach box, sort four items with the first one done for you, then answer three quick questions with the first one done for you. It takes 6 to 8 minutes and prints clearly in black and white. The focus skill is comparing explanations by their evidence, part of TEKS 4.3C: develop evidence-based explanations and communicate findings, conclusions, and proposed solutions.

Why It Works

Fourth graders can usually read a table before they can explain what it means. These sheets give them the words: claim, evidence, stronger, weaker. Each sheet stays inside one investigation, so students never have to hold two stories at once, and every question is one step. Wrong choices are believable, not silly. Pair it with the other five Grade 4 Explaining With Evidence sheets to cover explaining, proposing solutions, communicating, and discussion.
