Student lesson
- Precise words make clear science.
- Roots help decode new words.
- Everyday and scientific meanings can differ.
- A glossary helps revision.
Words to know
a testable prediction
letters added to the start of a word
letters added to the end of a word
a list of terms with meanings
1. Discover: The word detective
Ms Badu writes “thermometer” on the board. “Therm means heat; meter means measure,” she says. “What could a barometer, a speedometer and a photosynthesis tell us about roots?” The class decodes five new terms.
Think: Which root did you already know?
2. Understand: Words of science
Idea 1: Roots
Many science words come from Greek and Latin: bio (life), geo (Earth), photo (light), hydro (water), therm (heat), micro (small), -ology (study of). Knowing roots helps you decode new words.
Idea 2: Precision
Some words mean different things in science: force, power, work and theory. Use scientific words exactly, with units and evidence.
Idea 3: Glossary
Build a personal glossary with the word, meaning, example sentence and a small picture. Review it often.
3. Worked examples
Example 1 (I show you): Decode
Words.
- Root.
- Meaning.
- Example.
Answer: Meaning.
Example 2 (We do it together): Use
Precisely.
- Term.
- Unit.
- Evidence.
Answer: Sentence.
Example 3 (You try): Compare
Everyday and science.
Show the steps and answer
- Work.
- Force.
- Theory.
Answer: Difference.
Did you know?
The word “scientist” was only invented in 1833; before that, people were called natural philosophers.
Why this matters
Strong vocabulary makes secondary science textbooks easier to read.
4. Explore: Root detectives
Cut word cards for 20 science terms, match each to its root and meaning, then write five sentences using the terms accurately.
- Cut cards.
- Match.
- Check.
- Write.
Think about it: what did you notice?
What did you notice? Roots helped us guess unknown words.
5. Practise

If a learner struggles
- Find the misconception: “A theory is just a guess.” Well-tested explanation.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Use science words precisely.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child revises science vocabulary and word roots. You do not need to be an expert to help.
- Quiz your child on roots.
- Ask “What does that word mean?”
- Use words at home.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: recall key terms; use word roots; write precisely; build a glossary.
Prerequisite knowledge. Grade 6 ideas: Units 1 to 11 of Grade 6 Science.
Materials. Word cards, scissors, notebook. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare cards.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Write thermometer and ask, “What could this mean?”
Explanation (10 min). Teach vocabulary.
Guided activity (10 min). Learners match.
Independent activity (10 min). Learners write.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What does the root mean? What is the exact word?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “A theory is just a guess.” Well-tested explanation.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Use science words precisely. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
