Physical Properties

Make your own flipbook for IAN page 38

Take a blank sheet of paper from the blue folder and fold in half hamburger style

Open your paper and fold the two sides in to meet at the middle

Center fold

With the paper folded still, fold it in half hamburger style twice and then open You should have 8 boxes on your paper now like so:

Cut along each of the 6 folds to create 8 flaps – do not cut through the back of the paper!!!!

You should not have a flipbook that looks like this:

As we go over the different physical properties, write their name on the outside of one flap and their definition on the back of the flap You will add a picture for each later

1st flap – Physical Properties Physical properties are any

characteristic of matter than can be observed without changing what the matter is They can be observed using one or more

of your five senses EX: color, shape, odor, volume, mass,

strength, etc…

2nd Flap: Solubility The ability to dissolve into another

substance Ex: Salt is soluble in water

It dissolves in water to make salt water What are other examples of solubility?

Sugar Kool aid Alka seltzer

3rd Flap: Ductility The ability to be pulled into wires

Ex: copper is used for most wiring in electronics because of its high ductility – it can be made into very thin, very long wires

Doesn’t always have to be thin What are some other examples of

ductility? Platinum, silver and gold in jewelry Iron used to make screws and bolts

4th flap: Malleability The ability to mold and shape matter

Often describing how well it flattens out Ex: aluminum for cans and foil

What are other examples? Iron flattened into wrenches Steel flattened to make work surfaces Gold can be flattened to make gold leaf for

decorating

5th Flap: melting Point The temperature where a substance

changes from a solid to a liquid EX: when ice reaches its melting point, it

changes to liquid water What are other examples?

Popsicle melting Crayons melting Wax melting

6th flap: Boiling Point The temperature where a substance

changes from a liquid to a gas EX: when water boils and turns to steam

at 100 degrees C What are some other examples?

Aluminum boils at 2467 degrees C (4472 F!)

Gold boils at 2807 degrees C (5084 F!)

7th Flap: Electrical Conductivity The ability to allow an electric current to

flow through a material Allows electrons to move through EX: copper is highly electrically conductive

and is therefore used in electronics wiring

8th Flap: Thermal Conductivity The ability to pass heat through a

substance Metals are extremely thermal conductive

that is why they get so hot EX: car hood on a summer day

Other examples: metal spoon/fork in your hot dinner will

become hot itself because it is transferring that heat
