1. Physical Properties

2. What is Matter? Matter is – Anything that has mass and takes up space. – Ex. Solids, liquids, & gases. – ANYTHING = EVERYTHING

3. What is Mass? Mass is – A measure of the amount of matter in an object. We use the Metric System* (In science) – g or kg – Ex. A paper clip has a mass of 1 g and 1 kg is equal to 2.2 pounds(lbs)

4. What is Weight? Weight is – The effect of gravity on mass. This changes depending on where you are. – For example: You weigh 100 lbs on earth You weigh 16.6 lbs on the moon. http://www.exploratorium.edu/ronh/weight/

5. Volume & Density Volume is – The amount of space that an object takes up. We use – L (liters) for liquids – cm 3 (centimeters cubed) for solid objects. Density is – How tightly an object’s mass is packed into it’s volume.

6. Density, Mass, & Volume D= – Density M= – Mass V= – Volume Equation to remember: D= M/V or

7. What is an Element? An element is – A pure substance that is made of the same type of matter. An element CANNOT be – Broken down by physical OR chemical means. 92 occur in nature (natural) – The rest are man made (in lab) They are arranged by their – Atomic number on the periodic table.

8. What are Physical Properties? A physical property is a property that can be observed or measured – Without changing the substance itself. Ductile- – Can be pulled into a wire. Color, odor (how it smells), texture ( how it feels). Luster- – The way it reflects light.

9. More Physical Properties Hardness- – Resists being scratched Diamonds are the hardest and are a 10 on the MOHS scale. Conductivity- – How easily electricity or heat moves through it. Magnetism- – How it responds to a magnetic field. ( is it magnetic?) Malleable- – Can be hammered into sheets. Streak- – Color a mineral makes on a tile plate.

10. More Physical Properties Solubility- – How it dissolves in water. (Is it soluble?) Brittle- – How easily it breaks. Sonorous- – The sound produced when metal is struck. (Ex. A bell)
