Teacher’s Activity - extremely small when the substances undergoes a change in - from Greek word means Prayer composition “indivisible” -What When adding acid - have sub atomic particles is Biology? Weight Checking of - Combustibility - when atom joined together they are Referswhen to theburn gravitational attraction exerted by a attendance - Change in colour molecule Who-invented microscope? body of matter on an object - ex. H20 hydrogen is an atom and Ex. Sodium-large yellow Review - Potassium- violet - more mass of an object has the more oxygen is an atom also Before we proceed, GiveChemical some branches of Biology? every atom has the same number of changes gravitational force exerted let us recall thethe object masselectron and proton so it can’t run - changes depends on - We can notice the inpartly chemical things you have away you are in when we see: - can be change depending on where nucleus learned last meeting the universe - Gas formation the tiny central part of an atom Colour changes Now let’s start our circle tine, to start our new - contain proton and neutron - Ex.day Rust in metal (oxidation)Properties of matter neutron - Rocket ship - digestion - 0 or neutral or no charge Motivation Q. what are the 2 properties of matter?- + 1 is neutralize by -1 = 0 Proton Physical states of matter Word pool I will choose one of the student to stand answer - up theand positive charge the question? Electron V. Q. what are the 4 known states of matter? Encircle the word that you see in the board - negative charge - very tiny Physical properties Solid - 500 meters away from neutron or PresentationCan be observed without changing the substances. equal to 10x soccer field Have definite shape and volume - 84 out of 109 known element are metallic - 28 or ¼ is non metal Matter Ad. Non-matter or Energy

Gas What comes in your mind when you heard the Light neither have definite shape nor definite volume word matter?Q. Give some example of metals? x-rays

heat are energy that we also need to survive

Liquid - All metals except mercury Chemical is solid and has room Bond Have definite volume but no definite shape temperature - Is an attraction between atom that Matter is everything or anything that occupies - Malleable allows the formation of chemical space and has a mass..meaning to say Plasma - Good conductor of heat substances that contain 2 or more. everything that you think is made up of matter. Strong Mixture of sub atomic -particles nuclei and There are 3 kind of chemical bonding Physical Changes 1. Ionic bond involves the transfer of electrons Mass electrons from one another to Change in size and shape - the 99% of the observable universe Refers to the quantity of matter in anybody - Mixing of two different ex. Salad another so the atoms either losses or - Amount of matter in anWater objectchange in ice – liquid -vapour gain electrons. Q. which of the states of matter that has the - Always constant wherever you are in 2. Covalent bond sharing of electron ability to do the other kind of matter except the 3. Hydrogen bond it forms only the universe plasma? - Unit of mass is called grams/kgms between a few electronegative atoms like oxygen, fluorine and nitrogen.

Generalization Matter is anything that occupies space and has a mass. Mass is the amount of matter in an object.

Weight is the gravitational attraction exerted by a body of matter in an object. There are two properties of matter, the physical and the chemical properties. There are four known states of matter the solid, liquid, gas and plasma. The basic building block of matter is called atom. There are four parts of atom the nucleus, proton, neutron and the electron. The three kinds of chemical bonding are the ionic bond, covalent bond and the hydrogen bond. VI.
