What is Matter Matter is anything that has mass and takes up space. It is the “stuff” that makes up everything in the universe. Can be a solid, liquid or gas Everything around you is made up of matter. Chocolate cake is made up of matter. You are made of matter. Air is matter. Even though it is invisible, you know it is there when you feel a breeze or watch the trees bend from it. (balloon demo)

Matter Takes up Space Volume is the amount of space an object occupies or takes up. Because matter has volume (takes up space), it cannot share the same space with something else at the same time! All objects take up space. You are taking up space on the chair. **Occupying space demos with cup of water, marbles, bucket of water and crumpled piece of paper, balloon in a bottle

Measuring Volume Volume of liquids: Use a graduated cylinder Units: liters (L) or milliliters (mL) Show how to measure volume of liquid with demo!

Measuring Volume Volume of Solids: Volume of a Normal Shaped Solid Object: Use math! Volume= length (l) x width (w) x height (h) Volume of a Weird Shaped Solid Object Put it in water! Measure the change in water

Practice with Volume! What is the volume of this thing? What is the volume of this box? h = 2 cm l = 5 cm w = 1 cm Volume = l x w x h 5 x 1 x 2 = 10 cm

Matter Has Mass Mass is how much there is of an object The heavier the object the greater its mass Think of massive- what does that mean? (big, huge) bigger/heavier = more mass!

Difference Between mass and Weight The amount of matter in an object Does not change with location Weight = The pull of gravity on an object Changes depending on where you are The more mass an object has, the greater the gravitational force on the object and the greater the object’s weight.

Measuring Mass and Weight Use a triple beam balance Units: gram (g), kilogram (kg), milligram (mg) Weight: Use a spring scale Units: Newton (N) The more gram crackers you eat the more mass you have!
