I am doing a science project on Chemical and Physical changes. I need to know what they both are, how can you tell when you see one, and 5 examples of chemical and physical changes. I am going to do a poster on it and I need to have a cool way to present the poster to my class. By the way, I am in 9th grade honors science in high school. If you could help me on those things, that would be great. Thank You!!!
