Step 1: Begin by observing whether the transformation involves a change in composition or just in appearance. If the identity of the substance remains the same, it’s a physical alteration. If the substance itself is altered, a new material is formed, indicating a chemical shift.

Step 2: Pay attention to key indicators such as color change, gas production, or temperature variation. These often signal a reaction where one substance is converted into another, which is typical of chemical processes.

Step 3: Record your findings and compare with known reactions. For example, when a substance dissolves in water without altering its chemical structure, it’s a physical change. However, when heat is released and a new substance is formed, like when wood burns, it is a chemical shift.
