Hi, young learners! Welcome back to Primary 3 Basic Science & Technology. In our previous lesson, we learned about Description of keys on the keyboard and their functions. Today, we’re going to learn about INPUT DEVICES – Functions of the mouse.
Objectives
By the end of this lesson, you should be able to: * List the functions of the mouse * Demonstrate how to highlight a given text using a mouse * Demonstrate how to scroll up and down using a mouse * Demonstrate how to use a mouse and a keyboard to input your names into the computer
Functions of the Mouse
The mouse is an important part of a computer. It’s an input device, which means it helps us tell the computer what to do. Think of it like a remote control for your TV, but for your computer!
There are many things you can do with a mouse, such as:
- Selecting items: Clicking on something with your mouse tells the computer you want to choose it. For example, you can click on a picture to open it.
- Highlighting text: Dragging the mouse over words lets you select them, which is useful for copying or editing.
- Scrolling: Moving the mouse wheel up or down lets you see different parts of a webpage or document.
- Opening documents or launching applications: Double-clicking on an icon with your mouse opens a program or file.
Practical Use of the Mouse
Let’s see how the mouse works in practice!
- Highlighting text: Open a document or webpage on your computer. Place the mouse pointer over the text you want to highlight. Press and hold the left mouse button, and drag the mouse across the text. You’ll see the selected text change color. Let go of the button when you’ve highlighted the text you want.
- Scrolling: Find a webpage or document that’s longer than your screen. Use the mouse wheel to scroll up and down. Turn the wheel forward to move down the page, and turn it backward to move up.
Practical Use of the Mouse and Keyboard
Now, let’s try using both the mouse and keyboard together!
- Typing your name: Open a word processing program or a text editor. Click in the empty space where you want to type. Use the keyboard to type your name. You can use the mouse to move the cursor around if you need to make corrections.
Evaluation Questions
Now that you’ve learned about the functions of the mouse, let’s see if you can answer these questions:
- What are some of the functions of the mouse?
- How do you highlight text using the mouse?
- How do you scroll up and down with the mouse?
- How can you use the mouse and keyboard to input your name into the computer?
- Can you think of other ways the mouse is used on a computer?
Conclusion
You’ve learned a lot about the mouse today! Remember, it’s a powerful tool that helps us interact with our computers. Keep practicing using the mouse, and you’ll become a computer expert in no time!
