Let me carefully examine each item and decide whether it is a machine or not, based on the learning objective: *a machine is a device that does work or performs a task, often using energy* — especially a smart machine like a computer.
I’ll go row by row:
Row 1:
- Calculator → Yes, it’s an electronic device that performs calculations.
✔ machine
- Smartphone → It’s a smart device that processes information, runs apps, etc.
✔ machine
- Dog (cartoon) → A living animal, not built by humans to do work in this sense.
✘ Not machine
Row 2:
- Washing machine → Designed to wash clothes automatically.
✔ machine
- Flowers → Living plants, not machines.
✘ Not machine
- Desktop computer → Classic example of a machine (smart machine).
✔ machine
Row 3:
- Sun → Natural star, not a human-made machine.
✘ Not machine
- Airplane → Human-made vehicle that flies using engines; performs transport work.
✔ machine
- Butterfly → Living insect, not a machine.
✘ Not machine
Now I will confirm each with a quick check:
- Machines here = calculator, smartphone, washing machine, computer, airplane.
- Not machines = dog, flowers, sun, butterfly.
Final Answer:
calculator: blue
smartphone: blue
dog: green
washing machine: blue
flowers: green
computer: blue
sun: green
airplane: blue
butterfly: green
