By the end of the lesson, students will be able to:

1. Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled.
2. Understand the relationship between the pieces and the object they create.
3. Apply knowledge of matter and energy to explain the process of constructing and deconstructing objects.

Materials:

1. Various objects made of small pieces (e.g., building blocks, building bricks, puzzle pieces)
2. Pictures or diagrams of objects and their individual pieces
3. Drawing materials (paper, pencils, markers)
4. Observation sheets for students
5. Chart paper or whiteboard
6. Markers

Vocabulary:

1. Object
2. Pieces
3. Construct
4. Disassemble
5. Evidence-based
6. Account
7. Matter
8. Energy

Pre-lesson Discussion:

• Start with a discussion about the objects students encounter in their daily lives and how they are constructed.
• Introduce the idea that objects can be made up of smaller pieces and that these pieces can be taken apart and reassembled.

Lesson Activities:

1. Introduction to Objects and Pieces (CCC):

   • Show various objects made of small pieces to the class.
   • Discuss how these objects are constructed and what happens when the pieces are taken apart.

2. Observation and Discussion (SEP):

   • Engage students in observing the objects and their pieces.
   • Facilitate a class discussion on how the pieces fit together to form the object.

3. Hands-On Activity (SEP):

   • Provide students with a set of objects and pieces.
   • Allow them to disassemble and reassemble the objects, encouraging hands-on exploration.

4. Drawing and Describing (SEP):

   • Have students draw the objects and their pieces.
   • Ask them to describe the process of disassembling and reassembling the objects.

5. Class Discussion and Charting (CCC):

   • Lead a class discussion about the observations and experiences.
   • Chart key points on a whiteboard or chart paper.

Teacher Notes:

• Emphasize the importance of careful observation and encourage students to use descriptive language.
• Facilitate discussions about how energy is involved in the construction and deconstruction process.

Conclusion:

Wrap up the lesson by summarizing key observations and reinforcing the concept that objects are made up of smaller pieces. Discuss the role of matter and energy in the construction and deconstruction process. Encourage students to explore other objects in their environment and think about how they are constructed and can be disassembled.

Assessment:

• Observation Sheets (SEP):

  • Assess students based on their completion of observation sheets, focusing on the accuracy and detail of their observations.

• Class Discussion (CCC):

  • Evaluate student participation in the discussion about constructing and deconstructing objects and their ability to connect observations to the relationship between matter and energy.

• Drawings and Descriptions (SEP):

  • Assess the accuracy of students' drawings and descriptions, focusing on how well they communicate the process of constructing and deconstructing objects.
