Key Concepts Covered

➡️ Physical Changes – Changes that alter the form or appearance of a substance but do not create a new substance, such as melting, freezing, or cutting.

➡️ Chemical Changes – Changes that result in the formation of one or more new substances with different properties, such as rusting or burning.

➡️ Reversible vs. Irreversible Changes – Understanding when changes can be undone versus when they result in new substances.

➡️ Atoms and Molecules – The role of atomic rearrangement in chemical changes, emphasizing conservation of mass.

➡️ Indicators of Chemical Change – Observations like color change, gas production, or precipitation that indicate a chemical reaction is occurring.
