LabLearner’s 3-D Approach to Scientific Inquiry
Phase 1 – Defined Understanding
The defined boundaries of this phase provide a framework for engaging parents and identifying students’ current knowledge of the topic(s) being explored.
Phase 2 – Dynamic Understanding
Change, activity, and progress characterize the dynamic phase. Its design will enable you to enhance students’ existing skills, interests, and understanding, as well as meaningfully build new ones.
Phase 3 – Deeper Understanding
By this point, students have moved through powerful and purposeful tasks that had them actively and intentionally construct an understanding of concepts. In this final phase, students will consolidate knowledge and make deeper connections among ideas.
Phase 1 – Defined Understanding
► Questions to Investigate in this CELL
- How are physical and chemical weathering different?
- How do physical and chemical weathering combine to weather rocks?
► Parent Newsletter
Encourage parents to connect to their child’s learning by providing them with a framework of the CELL. Use this link to access and share the Parent Newsletter.
► Baseline Assessment
Assess students’ current knowledge of the topic(s) being explored then set instructional and student learning goals. Use this link to schedule then invite students to take the Pre-test for the CELL.
Phase 2 – Dynamic Understanding
► Introduction and Fun Facts
Enhance your conceptual understanding by reading the student-level research on the topic(s) being explored. Use this link to access the research.

► CELL Vocabulary
Chemical weathering: decomposition of rock material due to the chemical reaction of compounds in the rock with chemicals in the environment. Not all rocks are composed of the same chemicals or minerals, so chemical weathering affects rocks differently.
Erosion: the processes by which rock and soil materials are loosened or dissolved and transported from one place to another.
Minerals: the elements and compounds found in rocks are often called minerals. All minerals are solid and possess a crystal structure.
Physical weathering: disintegration or breaking of rock material into small fragments or pieces. In physical weathering, the chemical components of rock remain unchanged.
Rocks: mixtures of different elements and chemical compounds that combine in different proportions to form hard, solid materials of the Earth’s surface.
Soil: the mixture of organic components, sand, and gravel that makes up the upper surface of the Earth.

Phase 3 – Deeper Understanding
►Deep Analysis Classroom Discussion
These questions can be used to elicit in-depth discussions based on the lab experience. Teachers may use any or all of these discussion points depending on the time available.
► Summative Assessment
Evaluate student learning at the end of the CELL by comparing the Summative Assessment to students’ Baseline Assessments. Use this link to schedule then invite students to take the Post-test for the CELL.
