Experiments in class are super important for students. They help us understand the differences between physical and chemical changes.

Physical Changes

• What It Is: A physical change happens when the way something looks changes, but what it’s made of stays the same.
• Examples: Think about melting ice or boiling water. Ice melts at 0°C, and water boils at 100°C.
• Demonstration in the Lab: When we heat ice, it changes into water. We can see these changes happen at different temperatures.

Chemical Changes

• What It Is: A chemical change is when a substance changes into something new. This means that what it’s made of is different now.
• Examples: Rust forming on iron and burning fossil fuels are good examples of chemical changes.
• Demonstration in the Lab: When vinegar reacts with baking soda, it creates carbon dioxide gas.

Why Experiments Matter

Research shows that doing hands-on experiments can help us remember things much better—up to 70% better! When students participate in these activities, they get 50% better at telling the difference between chemical and physical changes.

These fun experiments not only make learning exciting but also help us understand science in a deeper way!
