In science, the Law of Conservation of Matter tells us that matter cannot be created or destroyed, only _____ . This means that during both chemical changes and physical changes, the total amount of _____ stays the same, even though its _____ might change. For example, when you burn a piece of paper (a _____ change), it may seem like the paper disappears, but its atoms are actually transformed into ash and gases. Similarly, when you melt an ice cube (a _____ change), the water molecules remain the same; they just change from a solid to a liquid state. Whether matter undergoes a dramatic chemical change or a simple physical change, the total number of _____ involved doesn't increase or decrease. This fundamental principle helps scientists understand and explain many processes in our world, from cooking in the kitchen to complex industrial reactions.

In science, the Law of Conservation of Matter tells us that matter cannot be created or destroyed, only transformed. This means that during both chemical changes and physical changes, the total amount of matter stays the same, even though its form might change. For example, when you burn a piece of paper (a chemical change), it may seem like the paper disappears, but its atoms are actually transformed into ash and gases. Similarly, when you melt an ice cube (a physical change), the water molecules remain the same; they just change from a solid to a liquid state. Whether matter undergoes a dramatic chemical change or a simple physical change, the total number of atoms involved doesn't increase or decrease. This fundamental principle helps scientists understand and explain many processes in our world, from cooking in the kitchen to complex industrial reactions.
