What is a physical change?
This is how you can chemically change a piece of paper.
What is burn it?
This is a measure of how much space an object takes.
What is volume?

This is the chemical property of burning an object.
What is flammability?
This is a measure of how tightly packed an object is.
What is density?
Two objects that have the same volume MUST have the same mass. (T/F)
What is false?
This is the difference between a physical change and a chemical change.
What is a change in appearance for a physical change, and a change in identity (what the substance is/becomes something new) for a chemical change?
This is the reason why erosion of soil IS a physical change.
What is the soil is just moving location? It is still soil.
This is what happens when an object made of iron oxides. (like an iron nail or part of a car)
What is rusting?
This is a measure of the pull of gravity on an object.
What is weight?

What are bubbling/fizzing, change in temperature, new color, light is given off, and a precipitate formed?
This is the reason why baking a cake is NOT a physical change.
What is the ingredients (such as flour, sugar, eggs) turn into new substances with new properties when high heat is added to them; so it is a chemical change?

This is the reason why a change in state of matter (example ice, water, water vapor) is a physical change.
What is the substance is still the same? (It is still H2O whether it is a solid/ice, water/liquid in a cup, or water vapor/gas)
This is a helpful question you could ask to determine if a change is physical?
What is .......? Examples: Was there a change of state of matter, size, shape, texture etc? Did just the appearance of the substance change?
