Scientific Explanation Vocabulary

Scientific Explanation Vocabulary Worksheet (Grade 6 Science, TEKS 6.3A)

Give grade 6 students the words they need to explain science with evidence. This one-page vocabulary sheet defines nine key terms in plain language, then puts them to work in a short story about testing paper towels.

What's Inside

• A word box with simple, kid-friendly definitions for all 9 words, with examples for several
• Activity 1: Students fill in five blanks in a story about which paper towel soaks up the most water
• Activity 2: Students circle the word that best completes four sentences
• A visual answer key with answers marked in red

Words covered: claim, evidence, reasoning, data, model, scientific principle, scientific theory, scientific explanation, and conclusion.

How Teachers Use It

Use it to preview words before a lesson, as a bell ringer, or as a review before a quiz. Every word is defined on the page, so no prior knowledge is needed. The sheet takes about 10 minutes, works for independent work, partners, or homework, and prints clearly in black and white.

This worksheet is part of the Science Vocabulary series for grade 6. It supports Texas TEKS 6.3, developing evidence-based explanations and communicating findings, and pairs with the Reading in Science sheets for the same standard, so students meet each word in a lesson and then review it here.

Why It Works

Students see each word with a short, clear definition, then use it in a real-world sentence or example instead of copying definitions. Activities stay at the circle, match, and fill-in level, so students build confidence while the answer key lets teachers check work fast.
