Grade 5 Term 1 Revision Questions

Grade five learners observed the above animal during a nature walk.

Which animal belongs in the same group with animal shown above?

• Turtle

• Frog

• Salamander

• Shark

Answer explanation

✅ The correct answer is: Turtle! 🐢

Why?

A chameleon is a reptile, and so is a turtle! Reptiles have dry, scaly skin and lay eggs on land. That makes them part of the same animal family.

Why not the others?

❌ Frog & Salamander – These are amphibians! They have wet, slimy skin and live both in water and on land. Chameleons don’t like water that much!

❌ Shark – Sharks are fish! 🦈 They breathe underwater using gills, but chameleons need air like us!

Fun Fact!

Did you know chameleons don’t change color to hide? They do it to show feelings—like when they’re happy or angry! 😃😡

Which of the following animals is an example of a vertebrate?

• Snail

• Spider

• Butterfly

• Lizard

Answer explanation

✅ The correct answer is: Lizard 🦎

Why?

A lizard has a backbone (spine), which makes it a vertebrate! All vertebrates have bones inside their bodies.

Why not the others?

❌ Snail 🐌 – No bones at all! It has a soft body and a hard shell.

❌ Spider 🕷️ – It has an exoskeleton (a hard outer body) but no backbone.

❌ Butterfly 🦋 – Like spiders, butterflies have an exoskeleton but no backbone.

Fun Fact!

Lizards can regrow their tails if they lose them! It’s their way of escaping from predators. 🦎✨

Below are examples of birds. Which one cannot move by flying?

• Dove

• Emu

• Duck

• Owl

Answer explanation

✅ The correct answer is: Emu

Why?

An emu is a large bird that cannot fly! Instead, it has strong legs and runs very fast—up to 50 km/h!

Why do the others fly?

🕊️ Dove – Flies high and fast! Often seen in cities and parks.

🦆 Duck – Flies, but also swims in water.

🦉 Owl – A great night-time flyer with silent wings!

Fun Fact!

Even though emus can’t fly, they have tiny wings—but they’re just too small to lift their big bodies! 😄

Grade five teacher wrote the following as symptoms of a certain condition or disease of the breathing system.

i) Shortness of breath.

ii) Pain in the muscle.

iii) Pain in the chest.

iv) Difficult in breathing.

v) Lack of taste and smell.

Which condition or disease has the above symptoms?

• Coughs

• Asthmа

• COVID - 19

• Allergy

Answer explanation

✅ The correct answer is: COVID-19 🦠

Explanation:

The symptoms listed match COVID-19, a viral disease that affects the breathing system.

• Shortness of breath – People with COVID-19 may struggle to breathe.

• Pain in the muscles & chest 💪❤️ – COVID-19 can cause body aches and chest discomfort.

• Difficulty in breathing 😞 – The virus can infect the lungs, making it hard to breathe.

• Loss of taste & smell 👃🚫 – A unique symptom of COVID-19! Many people with COVID-19 cannot smell or taste food.

Why not the other options?

❌ Coughs – Coughing is a symptom, not a disease.

❌ Asthma – Causes breathing problems but does not cause loss of taste or muscle pain.

❌ Allergy – Can cause breathing problems, but does not cause fever, chest pain, or loss of taste.

Fun Fact!

Did you know that some people with COVID-19 don’t feel sick but can still spread the virus? That’s why washing hands and wearing masks was so important! 😷✨

Grade 5 learners were taught about the breathing system. Which of the following shows the correct path of air when breathing in?

• Nose → Lungs→ Trachea

• Nose → Trachea → Lungs

• Diaphragm → Lungs → Trachea

• Lungs → Diaphragm → Trachea

Answer explanation

✅ The correct answer is: Nose → Trachea → Lungs

Explanation:

When we breathe in, air follows this path:

1️⃣ Nose – Air enters through the nose, where it is cleaned, warmed, and moistened. 👃
2️⃣ Trachea (Windpipe) – The air moves down the trachea, which is like a tube leading to the lungs.
3️⃣ Lungs – Air reaches the lungs, where oxygen is taken into the blood.

Why are the other options wrong?

❌ Nose → Lungs → Trachea – The air must pass through the trachea before reaching the lungs.

❌ Diaphragm → Lungs → Trachea – The diaphragm is a muscle that helps with breathing, but air does not pass through it.

❌ Lungs → Diaphragm → Trachea – This is the wrong order! Air goes to the lungs, not the diaphragm.

Fun Fact!

Your lungs have tiny air sacs called alveoli—they look like little balloons and help take in oxygen! 🎈😊

Which statement does not explain characteristics of fish as a group of vertebrates?

• Their bodies are covered with scales

• They lay eggs in water

• They breathe through gills when young and lungs when adult

• They have fins that help them to swim in water

Answer explanation

✅ The correct answer is: They breathe through gills when young and lungs when adult

Explanation:

Fish breathe through gills their entire lives! Unlike amphibians (like frogs) that change from using gills to lungs as they grow, fish never develop lungs.

Why are the other options correct?

✔️ Their bodies are covered with scales. – Most fish have scaly skin to protect their bodies. 🐟

✔️ They lay eggs in water. – Most fish lay eggs in water, where baby fish (called fry) hatch. 🥚🌊

✔️ They have fins that help them swim. – Fins help fish move and balance in water. 🏊‍♂️

Fun Fact!

Some fish, like sharks, don’t have bones! Their skeletons are made of cartilage, just like your ears and nose! 🦈

Grade 5 learners collected the materials given below to make a model of the breathing system. Which material did they use to represent the trachea?

• Rubber band

• Plasticine

• Balloon

• Straw

Answer explanation

✅ The correct answer is: Straw 🥤

Explanation:

The trachea (windpipe) is a tube that carries air from the nose to the lungs. A straw is the best material to represent it because it is hollow and allows air to pass through, just like the real trachea!

Why not the other materials?

❌ Rubber band – Used for tying things, but it doesn’t act like a tube.

❌ Plasticine – It is solid and cannot let air pass through.

❌ Balloon – Balloons are better for representing the lungs, since they expand and contract when filled with air. 🎈

Fun Fact!

The real trachea has small rings of cartilage to keep it open, just like how a straw doesn’t collapse when you suck on it! 😃

Which part of the breathing system relaxes to allow air out when breathing out?

• Lungs

• Nose

• Trachea

• Diaphragm

Answer explanation

✅ The correct answer is: Diaphragm

Explanation:

The diaphragm is a muscle below the lungs that helps with breathing.

• When you breathe in, the diaphragm contracts (moves down) to make space for air in the lungs.

• When you breathe out, the diaphragm relaxes (moves up) to push air out of the lungs.

Why are the other options incorrect?

❌ Lungs – The lungs don’t relax; they just shrink as air moves out.

❌ Trachea – The trachea is just a tube that carries air, it doesn’t control breathing.

❌ Nose – The nose helps air enter and exit, but it doesn’t make air move.

Fun Fact!

Did you know that hiccups happen when the diaphragm moves suddenly? That’s why you make a funny "hic!" sound! 😆

Grade 5 learners were asked in their groups to give examples of mammals that lay eggs. Who gave the correct answer?

• Maurine → Shark

• Beatrice → Bat

• Caroline → Spiny ant eater

• Deborah → Dolphin

Answer explanation

✅ The correct answer is: Caroline – Spiny Ant eater (Echidna) 🦔🥚

Explanation:

Most mammals give birth to live young, but there are two special mammals that lay eggs:

1️⃣ Echidna (Spiny Ant eater)
2️⃣ Platypus

These animals are called monotremes, and they are only found in Australia and New Guinea!

Why are the other options incorrect?

❌ Shark – Sharks are fish, not mammals. 🦈

❌ Bat – Bats are mammals, but they give birth to live babies, not eggs. 🦇

❌ Dolphin – Dolphins are marine mammals, but they give birth to live young, not eggs. 🐬

Fun Fact!

Even though echidnas lay eggs, they still produce milk to feed their babies—just like other mammals! 🍼😊

The picture above shows a certain plant. Use it to answer questions 10 and 11.

Which statement is not true about the plant?

• It produces flowers

• It has green leaves

• It does not produce flowers

• It makes food in the leaves

Answer explanation

✅ The correct answer is: It produces flowers. ❌🌸

Explanation:

Ferns do not produce flowers! Instead, they reproduce using spores, which are tiny dust-like structures found under their leaves.

Why are the other options correct?

✔️ It has green leaves. – Ferns have green, leafy fronds that help them make food. 🍃

✔️ It does not produce flowers. – True! Ferns never grow flowers. 🌱

✔️ It makes food in the leaves. – Like all green plants, ferns use photosynthesis to make food from sunlight. ☀️

Fun Fact!

Ferns are some of the oldest plants on Earth—they existed even before dinosaurs! 🦖🌿
