This is a worksheet that works well with the Matter Powerpoint posted on my TPT. It has 6 parts: Part 1 & Part 2 is a station lab activity that I do. I use marshmallows to demonstrate elements, compounds, mixtures of elements, mixtures of compounds, and both. They have to determine what it is and give reasons why. Part 3: Part 3 is similar to Part 1/2, but uses pictures. Part 4: Classifying Pure substances as elements or compounds Part 5: Classifying Mixtures as heterogeneous or homogeneous.

This is an editable Google Doc practice for Physical and Chemical Changes. There are 18 practice problems where students have to determine whether a physical or chemical change is taking place. For 8 of them, they must give reasons why. This is editable and an answer sheet is included.
