Hello, young learners! Welcome back to Primary 2 Basic Science And Technology. In our previous lesson, we learned about Uses of a Keyboard. Today, we’re going to learn about the Features Of A Mouse.
Objectives
By the end of this lesson, you should be able to:
- Identify two features of the mouse.
- Explain the importance of a mouse in using a computer.
Features Of A Mouse
A mouse is a small device that we use to control our computer. It’s like a tiny remote control for our computer screen! Let’s learn about some of its important features:
What is a Mouse?
A mouse is a common input device used to control a computer. It’s called a “mouse” because it looks like a small rodent.
The Main Features of a Mouse
There are several important features of a mouse, and they are:
- Size: A mouse is typically small and fits comfortably in the hand of the user, making it easy to move and control.
- Buttons: Most mice have at least two buttons – a left button and a right button. These buttons are used for various functions, such as selecting, clicking, and dragging.
- Scroll Wheel: Many mice have a scroll wheel between the two buttons. This wheel allows users to scroll up and down on a webpage or document without moving the entire mouse.
- Cord or Wireless: Mice can be either connected to the computer with a cord or operate wirelessly through technologies like Bluetooth. The corded ones have a cable, while wireless mice are battery-powered and communicate with the computer without a physical connection.
- Optical Sensor: Modern mice often use an optical sensor for tracking movement. This sensor detects movement on a surface, translating it into cursor movement on the computer screen.
Evaluation Questions
Now that you’ve learned about the features of a mouse, let’s see if you can answer these questions:
- What are two features of a mouse?
- Why is a mouse important when using a computer?
- What are the different types of mice?
- What is the function of the scroll wheel on a mouse?
- How does an optical sensor help a mouse track movement?
Conclusion
We’ve learned about the important features of a mouse, which is a crucial tool for using a computer. Remember, a mouse helps us control the cursor on the screen, allowing us to click, drag, and scroll. Keep exploring and learning about different computer devices! See you in the next lesson!
