Two students are making S’mores. Student 1 says that making S’mores is a physical change because the graham crackers, marshmallow, and chocolate are simply a mixture. Student 2 says that making S’mores is a chemical change because the marshmallow begins to burn when you place it in the fire and becomes dark and crispy on the outside. Who is correct and why?

• Student 1 is correct.

• Student 2 is correct.

• Both students are correct because making S’mores is a physical change when you put the substances together, but a chemical change also occurs when the marshmallow burns.

• Student 2 is correct because once the crackers, marshmallow, and chocolate are placed together, the mixture cannot be reversed again.
