Objectives: 1. Differentiate physical from chemical properties; 2. Observe materials and give their properties; and 3. Recognize their strengths and weaknesses.

EVERYTHING THAT SURROUNDS US IS MATTER.

WHAT IS MATTER?

Matter -anything that occupies space and has mass -it is made up of particles such as molecules and atoms -it is generally classified into three basic phases/states: solid, liquid and gas, with plasma sometimes added as the fourth state for scientific purposes.

Strengths Weaknesses

Properties of Matter 1. Physical Properties- this can be observed or measured without changing the substance into another substance. 2. Chemical Properties-properties that can only be identified when one substance reacts with another substance.

Physical Properties a. Intensive Properties- properties that depend on the kind of matter regardless of the amount - whether the amount is smaller or bigger, these properties do not change Ex. density, boiling point, melting point, color, texture, solubility, metallic properties like malleability and ductility, hardness

Density- the ability of an object to float or sink in water due to its mass and volume

Boiling, Melting and Freezing Point of an object is fixed.

Ductility- the ability of metals to be turned into wires.

Malleability- the ability of metals to be hammered into thin sheets.

Brittleness- the ability of matter to be broken easily.

Physical Properties a. Extensive Properties- properties that depend on the amount of the matter - it means that if the amount of matte is small, its quantity is small too. Ex. mass, volume, length, height, area

Chemical Properties Examples: a. combustion/flammability- the ability to burn b. corrosion- the gradual destruction of metals like rusting of iron c. oxidation- combination of substance with oxygen such as the browning of fruits when exposed to the air.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. a. The victims of a shipwreck hold tight on their floaters so that they will not sink in the water.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. b. Mother used LPG to heat the water that will be used in cooking her favorite dish.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. c. The carpenter hammered the iron sheet so that it will be more flattened and it can fit to the table that he is making.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. d. The chef put the frozen canister out the freezer to let the ice melt before he cook its content.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. e. The father smoked the meat so that it will be tenderized.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. f. The school add an extension building to come up with more rooms and to accommodate more students.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. g. The construction workers made the floor rough so that pedestrians will not slip off when it is wet.

Activity: Identify what property of matter is involved in the following situations. Determine if the property is physical of chemical. h. The students easily cracked the shell of the eggs that they will use for their dough.

Assignment: 1. Give 5 examples for each: a. Physical Change b. Chemical Change 2. Bring the following for the Lab. Activity tomorrow: a. Lab. Gown and hairnet (individual) b. Lab. Kit (shoe box, rags, masking tape, scissors, alcohol, tissue) c. Baking soda d. Vinegar (bottled; small amount only) e. Chalk

Good bye and God bless you all!
