Students identify machines vs. non-machines in this interactive worksheet.

Problem Description:

The task is to identify whether the objects in the images are machines or not. If an object is not a machine, you should place the color green in the box below it. If an object is a machine, you should place the color blue in the box below it.

Solution Approach:

1. Understand the Definition of a Machine: A machine is a device that performs or assists in performing physical tasks, often using energy to do so. Examples include calculators, phones, washing machines, computers, and airplanes.
2. Analyze Each Image: Carefully examine each image to determine whether the object depicted is a machine or not.
3. Mark the Boxes: Based on your analysis, mark the boxes with either green (for non-machines) or blue (for machines).

Step-by-Step Analysis of Each Image:

#### Row 1:
1. Calculator:
- A calculator is a machine because it performs mathematical calculations using electronic components.
- Mark: Blue (machine)

2. Smartphone:
- A smartphone is a machine because it processes information, communicates, and performs various tasks using software and hardware.
- Mark: Blue (machine)

3. Dog:
- A dog is a living organism, not a machine. It does not perform tasks using mechanical or electronic means.
- Mark: Green (not a machine)

#### Row 2:
4. Washing Machine:
- A washing machine is a machine because it uses electricity to wash clothes by spinning and agitating them.
- Mark: Blue (machine)

5. Flowers:
- Flowers are part of a plant, which is a living organism. They are not machines.
- Mark: Green (not a machine)

6. Computer:
- A computer is a machine because it processes data, runs programs, and performs tasks using hardware and software.
- Mark: Blue (machine)

#### Row 3:
7. Sun:
- The sun is a star, not a machine. It is a natural celestial body that emits light and heat through nuclear fusion.
- Mark: Green (not a machine)

8. Airplane:
- An airplane is a machine because it uses engines and other mechanical parts to fly and transport people or goods.
- Mark: Blue (machine)

9. Butterfly:
- A butterfly is a living organism, not a machine. It does not perform tasks using mechanical or electronic means.
- Mark: Green (not a machine)

Final Answer:

Based on the analysis, the markings for each image should be as follows:

| Image | Marking |
|---------------|---------|
| Calculator | Blue |
| Smartphone | Blue |
| Dog | Green |
| Washing Machine | Blue |
| Flowers | Green |
| Computer | Blue |
| Sun | Green |
| Airplane | Blue |
| Butterfly | Green |

Box Filling:

- For each image, fill the corresponding box with the color indicated above (green for "Not machine" and blue for "Machine").

Final Answer in Box Format:

\[
\boxed{
\begin{array}{ccc}
\text{Calculator} & \text{Smartphone} & \text{Dog} \\
\text{Blue} & \text{Blue} & \text{Green} \\
\hline
\text{Washing Machine} & \text{Flowers} & \text{Computer} \\
\text{Blue} & \text{Green} & \text{Blue} \\
\hline
\text{Sun} & \text{Airplane} & \text{Butterfly} \\
\text{Green} & \text{Blue} & \text{Green} \\
\end{array}
}
