Change It Up: Reversible and Irreversible Changes in Matter

The video tutorial explains the concepts of reversible and irreversible changes in matter. Reversible changes allow matter to return to its original state, often involving physical changes, while irreversible changes are permanent, often involving chemical changes. Examples of reversible changes include ironing a shirt, folding a paper airplane, and dissolving salt in water. Irreversible changes include cutting down a tree or cutting flowers. The video also discusses natural reversible changes, such as sand turning back into rock under pressure. A review section with questions helps reinforce the learning.
