Living Things Classification Worksheet

Classification of living organisms

🔬 Part 1: Understanding Classification

1. Why do scientists classify living things? Circle the best answer:

To make biology more difficult

To organise and understand biodiversity

To create more work for students

To confuse people about nature

2. How many main kingdoms of living things are there?
3. List the five kingdoms of living things:

🌿 Part 2: Kingdom Characteristics

4. Match each kingdom with its main characteristics:
1. Animalia
2. Plantae
3. Fungi
4. Protists
5. Bacteria
A. Unicellular, very small, different cell structure
B. Multicellular, moves, eats other organisms
C. Absorbs nutrients, mostly decomposers
D. Multicellular, makes own food by photosynthesis
E. Mostly unicellular, mixed features
5. Which kingdoms can make their own food? Check all that apply:

Animalia

Plantae

Fungi

Protists (some)

Bacteria (some)

📸 Part 3: Organism Classification Activity

Instructions: For each organism described below, identify which kingdom it belongs to and explain your reasoning based on the observable characteristics.

6. Organism A: Kākāpō (Kakapo parrot)
Description: A large, flightless bird native to New Zealand. It moves around by walking and climbing, feeds on native plants, fruits and leaves. It has feathers, a beak, and lays eggs.

Kingdom: ________________

Key characteristics that helped you decide:

7. Organism B: Pōhutukawa Tree
Description: A large tree with red flowers found along New Zealand coastlines. It has roots, stems, leaves, and produces its own food using sunlight. It cannot move from place to place.

Kingdom: ________________

Key characteristics that helped you decide:

8. Organism C: Bracket Fungus
Description: A shelf-like growth found on dead tree trunks. It has no leaves or roots, cannot move, and feeds by breaking down dead wood material. It reproduces using spores.

Kingdom: ________________

Key characteristics that helped you decide:

9. Organism D: Amoeba
Description: A tiny, single-celled organism visible only under a microscope. It can change shape and move by extending parts of its body. It feeds by surrounding and absorbing food particles.

Kingdom: ________________

Key characteristics that helped you decide:

10. Organism E: E. coli Bacteria
Description: Extremely tiny, single-celled organisms found in the human digestive system. They are much smaller than other single-celled organisms and have a different internal structure with no nucleus.

Kingdom: ________________

Key characteristics that helped you decide:

11. Organism F: Tuatara
Description: A reptile native to New Zealand that looks like a lizard. It moves by walking, hunts insects and small animals for food, has scales, and can regulate its body temperature using the environment.

Kingdom: ________________

Key characteristics that helped you decide:

🧠 Part 4: Critical Thinking

12. Some organisms can be difficult to classify. Explain why scientists sometimes change how they classify living things:
13. Fill in the blanks about classification:

Classification helps scientists _____________ and study the incredible _____________ of life on Earth. As new _____________ is discovered and technology improves, scientists may _____________ how they group certain organisms.

14. Design your own classification activity: If you had to sort the students in your class into groups, what characteristics would you use? List at least three:
15. Circle the statement that best describes scientific classification:

Classification never changes once it's decided

Classification is based on opinions, not facts

Classification changes as we learn more about organisms

Classification is only useful for plants

🎨 Part 5: Creative Application

16. Draw and label an example organism from each kingdom in the space below:
17. Reflection: What was the most interesting thing you learned about classification today?
18. How might understanding classification help you in everyday life or future studies?
