Sinking and Floating Objects

The structured inquiry approach significantly enhances student learning outcomes by fostering a systematic process of questioning, investigation, and analysis, thereby cultivating critical thinking and problem-solving skills (Walden University, 2023; Pedaste et al., 2015). This method encourages active engagement with content, facilitating connections between theoretical frameworks and real-world applications (Krajcik & Blumenfeld, 2006).

In the provided work samples, the efficacy of this approach is evident through several key indicators:

1. Inquiry Process Articulation: Students’ artifacts demonstrate a clear progression through the inquiry cycle, including question formulation, data collection, and analysis (Pedaste et al., 2015).

2. Conceptual Mastery: The samples reflect accurate application of subject-specific concepts, underscoring the development of robust knowledge structures (Krajcik & Blumenfeld, 2006).

3. Reflective Reasoning: Written reflections exhibit enhanced metacognitive awareness, with students evaluating outcomes and connecting findings to prior knowledge.

4. Skill Development: The work showcases growth in essential competencies, including data interpretation and communication of results (Walden University, 2023).

As noted by Walden University (2023), “Inquiry-based learning empowers students to take ownership of their educational journey, fostering a deeper, more enduring understanding.” This aligns with Pedaste et al.’s (2015) framework, which emphasizes the iterative nature of inquiry as a catalyst for transformative learning experiences.

Appendix A: Samples of Student Work

Sample 1: Student Prediction and Observation Worksheet

Description:
This scanned worksheet shows a student’s predictions and test results for objects that float or sink (e.g., apple, golf ball, scissors, ruler, paper clip, crayon, pencil). The student recorded both predictions and actual outcomes after testing each object in water.

The worksheet demonstrates the student’s ability to:

• Make predictions prior to investigation

• Test objects systematically

• Record observations accurately

• Compare predictions with results

Teacher markings indicate feedback and confirmation of correct observations, showing formative assessment in action.

Sample 2: Student-Created Push and Pull Force Model

Description:
This photograph shows a student-designed model constructed from recycled materials (e.g., cardboard, bottle caps, and packaging). The model was created to investigate how push and pull force work.

Evidence of Learning:
The model demonstrates:

• Application of inquiry concepts to a real-world design task

• Understanding that objects can float depending on material and structure, not just size

• Engagement in hands-on problem-solving

This artifact supports NSTA Standard 2b by showing learning through investigation and model construction.

Sample 3: Investigation Setup – Floating Test

Description:
This image shows the experimental setup used by students to test whether objects float or sink. A plastic container filled with water was used to test a plastic bottle cap, which is shown floating on the surface.

Evidence of Learning:
This image documents:

• Proper use of materials during investigation

• Direct observation of floating behavior

• Safe and appropriate handling of equipment

The photo serves as visual evidence of student participation in the inquiry process.

Appendix C: Assessment Findings and Graphic Representations of Student Learning

Assessment Findings (Based on Student Work Samples)

Summary of Results:

• Most students accurately predicted and recorded whether objects floated or sank.

• Students demonstrated strong observational skills during hands-on testing.

• Some students were able to explain results using simple scientific reasoning (e.g., “It floats because it is light”), while others needed prompting to explain why objects floated or sank.

Instructional Implications

The student work samples indicate that structured inquiry was effective in supporting observation and data collection skills. However, additional instruction is needed to strengthen students’ ability to explain results using scientific reasoning. Future lessons will include sentence starters and Claim–Evidence–Reasoning (CER) frameworks to support explanation development.
