ClassX Video Lessons Youtube Channel Next Generation Science Is Folding Paper a Physical or Chemical Change
Have you ever folded a piece of paper to make a paper plane? It’s a lot of fun! But did you know that when you fold paper, you’re doing something called a “physical change”? Let’s find out what that means!
A physical change is when something changes its shape or form, but it doesn’t turn into something new. When you fold a piece of paper, you’re changing how it looks, but it’s still paper. You can unfold it, and it will be the same paper as before. That’s why folding paper is a physical change.
A chemical change is different. It’s when something new is made. For example, when you bake a cake, the ingredients mix together and change into something new—a yummy cake! You can’t turn the cake back into the original ingredients. That’s a chemical change.
Here are some more examples of physical changes you might see every day:
Now you know that folding a paper plane is a physical change because it only changes the shape of the paper, not what the paper is made of. Next time you make a paper plane, you can think about how you’re doing a cool science experiment!
Science is all around us, and there are so many fun things to learn. Keep asking questions and exploring the world to discover more amazing things!
Paper Folding Experiment: Try folding different types of paper, like newspaper, construction paper, or tissue paper, into different shapes. Can you make a boat, a hat, or a flower? Observe how each type of paper behaves when you fold it. Does it tear easily, or is it sturdy? Discuss with a friend or family member why folding is a physical change and how the paper remains the same even after folding.
Physical Change Scavenger Hunt: Go on a scavenger hunt around your home or classroom to find examples of physical changes. Look for things like a sponge that has been squeezed, a pencil that has been sharpened, or a piece of clay that has been molded. Make a list of the items you find and share with the class. Talk about how each item is still the same material, just in a different form.
Observation Journal: Start a journal where you draw or write about physical changes you notice in your daily life. For example, you might see water freezing into ice or a balloon being inflated. Each time you observe a physical change, note down what changed and what stayed the same. Share your journal entries with your classmates and discuss why these changes are not chemical changes.

**Physical and Chemical Change: Identifying Changes**
Is folding a paper plane an example of a physical or chemical change?
Folding a piece of paper to make a paper plane changes its shape and form, but no new matter is produced. Therefore, folding a paper plane is an example of a physical change.
