### Physical Properties

Make your own flipbook for IAN page 38

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
