Lesson on Common I.T Devices – Wristwatches for Primary 1

Hi, young learners! Welcome back to Primary 1 Basic Science and Technology. In our previous lesson, we learned about Common I.T Devices – Pager. Today, we’re going to learn about Common I.T Devices, specifically Wristwatches.

Objectives

By the end of this lesson, you should be able to:

• Identify and name different types of Wristwatches
• List 2 uses of a wristwatch

Common I.T Devices – Wristwatches

Wristwatches: are devices worn on the wrist to tell time.

Types of Wristwatches

There are three main types of wristwatches, and they are:

1. Analog wristwatch: This type of wristwatch uses hands to indicate the time. The hands move around a circular dial with numbers or markings that represent the hours, minutes, and sometimes seconds.
2. Digital wristwatch: This type of wristwatch displays the time using numbers on a digital screen. They often have additional features like alarms, stopwatches, and timers.
3. Smart wristwatch: These are advanced wristwatches that connect to your smartphone and can do many things besides telling time. They can track your fitness, send messages, make calls, and even control your music.

Uses of Wristwatches

Some of the common uses of wristwatches include:

1. Time telling: This is the primary function of a wristwatch. It helps you know what time it is.
2. Setting alarms: Many wristwatches have alarm functions that allow you to set reminders for specific times.
3. Tracking fitness: Smart wristwatches can track your steps, distance, heart rate, and other fitness data.
4. Making calls and sending messages: Some smart wristwatches allow you to make calls and send messages without needing your phone.
5. Controlling music: You can use some smart wristwatches to control the music playing on your phone.
