1. September 9, 2014 Objective: 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 Agenda: 1)Complete Intro to Matter Notes a)Intro to Matter pgs 4-10 b)PowerPoint Notes Homework: No Homework

2. 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

3. 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

4. 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*

5. 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

6. Exit Slip 1.What are the two properties of matter? 2.How is volume measured? What units are used? 3.How is mass measured? What units are used? 4.Do objects with large masses always have large weights? Explain your reasoning.
