Add the Vocabulary of an Expert

Identify and define domain-specific vocabulary words related to the topic, adding them to strengthen the report.

Real experts use specific vocabulary words for their topic -- words a beginner might not know. Using a few of these words (and explaining them) makes your report sound like it was written by someone who really knows the subject.

When you use an expert word, briefly define it in the same sentence or the next one, so your reader is not left confused. "Octopuses use camouflage, which means blending in with their surroundings, to hide from predators."

Do not overload your report with too many hard words -- a few well-chosen, well-explained ones are more effective than a report full of confusing vocabulary.

📋 For the teacher
Teach it (10–15 min):
  • Look through your child's sources together to find two or three genuine expert vocabulary words already used there.
  • Practice the pattern "word, comma, quick definition" out loud together before writing it into the report.
  • Limit this week to two or three new vocabulary words -- quality of explanation matters more than quantity of words.
  • Ask your child to explain an expert word back to you in their own words, to check real understanding, not just copying.
Talk about it:
  • What expert vocabulary word did you add to your report?
  • How did you define that word for a reader who might not know it?
  • Why is it important to define a hard word instead of assuming the reader already knows it?

Mastery looks like: They add at least one genuine, topic-specific vocabulary word to the report and define it clearly within the sentence.

Common stumbles: Using an expert word without explaining it; overloading a paragraph with too many unfamiliar words at once.
