Title: Exploring Laboratory Apparatuses

Grade Level: 7th Grade

Duration: 60 minutes

Subject: Science

Objective: - Students will be able to identify and describe common laboratory apparatuses. - Students will understand the purpose and proper use of each apparatus. - Students will demonstrate safe handling and care of laboratory apparatuses.

Materials: - Laboratory apparatuses (beakers, test tubes, graduated cylinders, pipettes, etc.) - Safety goggles - Handouts with images and descriptions of laboratory apparatuses - Whiteboard or blackboard - Markers or chalk - Worksheets for students to practice identifying apparatuses

Procedure:

1. Engage (5 minutes): - Begin the lesson by asking students if they have ever been to a science laboratory and what they observed there. - Discuss the importance of laboratory apparatuses in conducting experiments and investigations. - Show students a few laboratory apparatuses and ask if they can identify them.

2. Explore (10 minutes): - Distribute handouts with images and descriptions of laboratory apparatuses to each student. - Ask students to work in pairs or small groups to match the apparatuses with their descriptions. - Encourage students to discuss and share their answers with the class.

3. Explain (10 minutes): - Write the names of the laboratory apparatuses on the board. - Explain the purpose and proper use of each apparatus, emphasizing safety precautions. - Demonstrate how to handle and use each apparatus correctly. - Encourage students to ask questions and clarify any doubts.

4. Elaborate (15 minutes): - Divide the class into small groups. - Distribute worksheets with images of laboratory apparatuses. - Instruct students to label each apparatus correctly and write a brief description of its purpose. - Circulate around the classroom to provide guidance and answer questions.

5. Elaborate (10 minutes): - Bring out the actual laboratory apparatuses and place them on a table at the front of the classroom. - Allow students to come up one by one or in small groups to examine and handle the apparatuses. - Remind students of the importance of safety goggles and proper handling.

6. Evaluate (5 minutes): - Conduct a quick review by asking students to name and describe a few laboratory apparatuses. - Assess their understanding by observing their interactions with the apparatuses during the hands-on activity.

7. Extend (5 minutes): - Discuss real-life applications of laboratory apparatuses, such as in medical laboratories, food testing, or environmental research. - Encourage students to explore further by conducting simple experiments at home using safe apparatuses like beakers or test tubes.

Note: Throughout the lesson, emphasize the importance of safety, proper handling, and care of laboratory apparatuses.
