Chemical and physical changes are related to chemical and physical properties chemical changes chemical changes take place on the molecular level a chemical change produces a new substance. What is a chemical change a chemical change is when 2 substances are mixed together to form something new this differs from a physical change, which is a substance changing physical forms but still retains its original properties sometimes when a mixture is made it can be hard for kids to tell if a chemical change has occurred. This is a fun partner activity that i use as part of my chemistry unit to get students thinking about the differences between physical and chemical changes each pair of students is given a set of cards with images and descriptions of either a physical change or a chemical change.

A physical change involves a change in physical properties physical properties can be observed without changing the type of matter examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, ph and density. Tip: color can be either chemical or physical and is a part of both lists (crayons produce a change in color, but is physical, burning wood produces a change in color and is chemical) they have to describe in detail what a reader would need to observe to determine if a reaction is chemical or physical. • the paper is cut into two pieces • is it still paper • was this a physical or chemical change #2) cutting paper when you use a pair of scissors to cut paper, you are separating a larger sheet of.
