Understanding Physical and Chemical Changes in Matter

Figuring out the differences between physical and chemical changes in matter can be tough.

1. Physical Changes:

• These changes affect how something looks or its shape.
• The substance itself stays the same. For example, when ice melts, it's still water.
• Sometimes, it can be hard to notice all the ways things can change physically.

2. Chemical Changes:

• These changes create new substances.
• Once a chemical change happens, you usually can't go back to what it was. A good example is rusting metal.
• Some chemical reactions can be pretty confusing for students.

To make things easier, students should try hands-on experiments and look at pictures or videos. These tools can really help clarify these concepts!
