Grade: 1st

Subject: Science

Topic: Introduction to Electrical Appliances

Time: 35 minutes

Objective: - Students will be able to identify common electrical appliances. - Students will understand the basic concept of electricity and its use in appliances. - Students will learn about the importance of electrical safety.

Materials: - Pictures or flashcards of common electrical appliances (e.g., refrigerator, television, toaster, fan, lamp, etc.) - Chart paper and markers - Whiteboard and markers - Safety posters or visuals - Extension cord (optional)

Procedure:

1. Introduction (5 minutes)
   • Begin the lesson by asking students if they know what electricity is and how it is used in their daily lives.
   • Show them a picture of an electrical appliance and ask if they can identify it.
   • Explain that today, they will be learning about different electrical appliances and how they work.
2. Identifying Electrical Appliances (10 minutes)
   • Show pictures or flashcards of various electrical appliances one by one.
   • Ask students to raise their hands and identify each appliance.
   • Write the names of the appliances on the chart paper or whiteboard as they are identified.
   • Discuss the purpose of each appliance and how it helps us in our daily lives.
3. Understanding Electricity (10 minutes)
   • Explain to students that electricity is a form of energy that powers these appliances.
   • Draw a simple diagram on the whiteboard to show how electricity flows from a power source (e.g., outlet) to the appliance.
   • Discuss the concept of on/off switches and how they control the flow of electricity to the appliance.
   • Emphasize the importance of not touching electrical appliances with wet hands or when standing on a wet surface.
4. Electrical Safety (5 minutes)
   • Show safety posters or visuals that depict electrical safety rules.
   • Discuss the importance of not inserting fingers or objects into electrical outlets.
   • Explain the dangers of playing with electrical cords or pulling them out forcefully.
   • Emphasize the need to ask an adult for help when dealing with electrical appliances.
5. Recap and Conclusion (5 minutes)
   • Review the names of the electrical appliances discussed during the lesson.
   • Ask students to share one thing they learned about electrical appliances or electricity.
   • Summarize the importance of using electrical appliances safely and responsibly.
   • Conclude the lesson by reminding students to always seek adult supervision when dealing with electricity.

Extension Activity (optional): - If time permits, set up a small demonstration using an extension cord and a lamp to show students how electricity flows from the outlet to the lamp when it is turned on. - Allow students to take turns plugging and unplugging the lamp (with adult supervision) to reinforce the concept of electrical safety.

Assessment: - Informally assess students’ understanding throughout the lesson by asking questions and observing their participation. - Use the extension activity as an opportunity to assess students’ comprehension and ability to apply the concepts learned.

Note: Ensure that all electrical demonstrations and activities are conducted under adult supervision to ensure safety.
