Student lesson
- There are five oceans.
- The Pacific is the largest and deepest.
- Oceans give food, transport and weather.
- Sierra Leone has a coast on the Atlantic Ocean.
Words to know
a very large body of salt water
a steady flow of water in the sea
the land beside the sea
a sheltered place where ships can stay safe
1. Discover: Salt water everywhere
Mr Cole points to the blue parts of the globe. “About seventy of every hundred parts of the Earth’s surface are covered by ocean,” he says. “They are connected, so one big world ocean has five named parts.” Mei traces the Atlantic. “This touches Sierra Leone,” says Mr Cole. “Freetown has one of the great natural harbours of West Africa.”
Think: What does the ocean give to people near the coast?
2. Understand: The five oceans
Idea 1: The five oceans
The five oceans are the Pacific, Atlantic, Indian, Southern and Arctic. The Pacific is the largest and deepest; its Challenger Deep, in the Mariana Trench, is about 11 kilometres deep. Oceans cover about 71 percent of the Earth.
Idea 2: Why oceans matter
Oceans give fish and other food, carry ships and trade, shape weather and climate, and hold huge amounts of heat. A current carries warm or cold water across the sea. A good harbour protects ships along a coast; Freetown’s deep natural harbour is one of the finest in West Africa.
Idea 3: Caring for oceans
Plastic waste, oil spills and too much fishing harm ocean life. People can protect the sea by keeping beaches and rivers clean, reducing single-use plastic and following fishing rules. Protecting ocean life helps coastal families in places such as Sierra Leone.
3. Worked examples
Example 1 (I show you): Name
Three oceans.
- Think.
- List.
- Say.
Answer: Pacific, Atlantic, Indian.
Example 2 (We do it together): Locate
Sierra Leone’s ocean.
- Think.
- Say.
- Check.
Answer: Atlantic.
Example 3 (You try): Explain
One use.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Fishing.
Did you know?
The Pacific Ocean is larger than all the Earth’s land put together.
Why this matters
Oceans give food, shape the weather and connect the world.
4. Explore: Ocean map
Label the five oceans on an outline world map. Draw a ship route from Sierra Leone across the Atlantic and add two uses of the sea.
- Label.
- Draw.
- Add.
- Share.
Think about it: what did you notice?
What did you notice? Oceans link places.

If a learner struggles
- Find the misconception: “The oceans are separate.” They are connected.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make an ocean poster.
- 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 learns about oceans. Please stress safe behaviour near water. You do not need to be an expert to help.
- Look at maps.
- Talk about water safety.
- Reduce plastic.
- 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: name five oceans; locate them; describe uses; explain ocean care.
Prerequisite knowledge. Grade 3 ideas: reading maps, directions, keys, scale and physical and political maps.
Materials. Outline maps, atlas. 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 ocean maps.
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). Tell the salt water story.
Explanation (10 min). Teach oceans.
Guided activity (10 min). Ocean map.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Why do oceans matter and how can we protect them?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “The oceans are separate.” They are connected.
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. Make an ocean poster. Enrichment. Find one new example near your home or school, draw or write about 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.
