Reading science with context clues
Informational text builds knowledge and vocabulary. This passage defines science words right in the sentences — magma, lava, erupt — so readers can use context clues to learn them, while the whole text supports one main idea about how volcanoes form.
How to use it
Have students underline the clue words that define each science term, then state the main idea. Builds on the honeybees passage and pairs with the water cycle passage.
👩🏫 Teacher note
Vocabulary in context (magma, lava, erupt) is a focus. Have students underline the clue words that define each term in the passage.
🏠 Parent note
When your child meets a hard word, have them reread the sentence to find clues to its meaning.
Common Mistakes to Watch For
- Choosing a detail as the main idea
- Guessing word meaning without using context
