What is the definition of Mass and Volume? What is their unit?
Mass is the amount of matter something is made of. Volume is the amount of space something takes up. Mass is measured in grams Volume is measured in cm3

What is the difference between physical properties and physical change?
Physical properties are what you are observing about an object using your 5 senses. Ex: color, size, shape, volume, density, mass, State of matter, etc. Physical change is when a substance changes in size, shape, state of matter, and how it looks. Ex: cutting an orange, crushing rocks

Explain the difference with physical and chemical change.
Physical change is when a substance changes is size, shape, and looks. No new substance is formed. Can mostly be reversed. Chemical change is when a new substance is formed and it cannot be reversed.

What are the two methods you use to find volume? (cube shaped object and an irregularly shaped object) What do you use to find mass?
Volume: L x W x H, Water displacement Mass: Use a scale

What is the difference between chemical properties and chemical change?
Chemical properties are saying what change a substance can go through, but is not actually changing. Ex: paper is flammable, but it is not currently being lit on fire. Chemical change is when a substance goes through a change and turns into a new substance that cannot be reversed. Ex: The wood is burning
