Science Context Answer Key
About This Worksheet
This Grade 7 Language Arts worksheet helps students use a nonfiction passage to determine the meanings of scientific words. The article explains how scientists monitor volcanoes using tools, observations, and long-term data. Students define bold terms such as seismograph, emissions, data, and predict by studying how each word is used in the passage. For example, the description of a device that records vibrations helps readers understand what a seismograph does.
Learning Goals
The main goal is to help students use context clues while reading subject-area nonfiction. Students should already be able to locate bold vocabulary and identify nearby details. This activity moves them toward explaining word meaning with evidence from definitions, examples, and descriptions in the text. It supports CCSS.ELA-LITERACY.L.7.4 and CCSS.ELA-LITERACY.RI.7.4, which focus on determining the meanings of academic and technical terms in context.
Student Tasks
On this worksheet, students will read a short passage titled “Watching Volcanoes.” They will write a meaning for four bold scientific words using information found in the article. Afterward, students select one vocabulary term and copy the exact clue that helped them understand it. Their answers should show that the definition came from the passage rather than from guessing or outside knowledge.
Common Challenges
Some students may copy an entire sentence without identifying which words actually give the clue. Others may know a scientific term already but fail to explain how the passage supports that meaning. Words such as data and predict may also seem familiar, yet students still need to define them accurately in this context. Encourage them to underline the smallest useful phrase before writing the definition.
Teaching Suggestions
A teacher can model one term by covering the bold word and reading the surrounding sentence aloud. The class can suggest a simple replacement that preserves the meaning. At home, a parent can ask the child to explain each term as though speaking to someone who has never studied volcanoes. This keeps the definitions clear and prevents students from repeating complicated wording they do not fully understand.
Worksheet Features
The worksheet combines a short science passage with four focused vocabulary questions. Bold print makes the target terms easy to locate, while the article provides direct and indirect clues. A final “Show the Clue” section requires students to connect one definition to exact evidence. This page is useful for context-clue lessons, science integration, independent reading, or homework.
