September 9, 2014Objective: I will know the 2 properties of matter, it’s 3 states, and how to calculate it’s mass and volume.Entry Task:* Read (Black & Red Book): Where Did Matter Come From?

pgs. 14-16* Explain where scientists believe all matter originated from

Matter Has Mass

• Mass is a measurement of the amount of matter an object is made of

• Object’s mass can only change if amount of matter changes.– Breaking – Burning– Dissolving – Growing

Mass VS Weight

• Gravity– Force of attraction between objects due to mass– All matter has mass – all matter experiences

gravity– Amount of attraction depends on 2 things• Mass• Distance

Mass VS Weight

• Weight– A measure of the gravitational force exerted on

an object– As distance between objects increases, the

gravitational force decreases.– A brick floating weightless in space would weigh

less than it does on Earth BUT it’s mass would remain the same.

*An objects mass is constant – weight is not*

Mass VS Weight

• Standard unit of mass = kilogram (kg) grams (g) and milligram (mg)

• Standard unit of weight = newton (N)– 1N = 100g mass on earth
