Small rocks.
Vinegar (for chemical weathering).
Freezer (for physical weathering).
Soil or moss (for biological weathering).
Notebooks and pencils..Introduction to Weathering: Explain the different types of weathering and their effects on rocks.
Conduct Experiments:
Chemical weathering: Soak rocks in vinegar and observe changes.
Physical weathering: Place rocks in water, freeze them overnight, and observe cracks.
Biological weathering: Place rocks in soil or moss and observe changes over time.
Observe and Record: Note the effects of each type of weathering in notebooks.
Discussion: Discuss how weathering shapes landscapes and contributes to soil formation.
Analysis: Compare the results of different weathering types and analyze their impact on rocks and landforms.
