 SHAN PRAYER Let us remember that we are in the most Holy presence of God. I will continue, Oh my God, to do all my actions for the love of You. Oh, Sacred Heart of Jesus, Thy Kingdom come, Live Jesus in our hearts. Amen.  GROUP PRESENTATION!  RECALL! MODIFIED TRUE OR FALSE. Determine whether the statement is true or false. If the statement is true, simply raise your right hand. If the statement is false, simply raise your left hand and correct the statement by changing only the part that makes it false. You must provide the correct information to replace the incorrect part. RECALL! Example: Statement: “Water boils at 90 °C at sea level. Response: “False. Water boils at 100 °C at sea level. RECALL! In terms of state, matter can be classified as a pure substance or a mixture. FALSE In terms of composition, matter can be classified as a pure substance or a mixture. RECALL! A metalloid exhibits some properties of metals and nonmetals. TRUE RECALL! Metals are said to be ductile because they have the ability to be hammered into thin sheets without breaking or cracking. FALSE Metals are said to be malleable because they have the ability to be hammered into thin sheets without breaking or cracking. Ductile refers to the ability to be stretched into wires.  RECALL! The particles in suspensions are smaller than the particles in colloids. FALSE The particles in suspensions are bigger than the particles in colloids. RECALL! Compounds are substances composed of two or more kinds of atoms that are chemically bonded together in fixed proportions. TRUE CLASSIFY ME!

Matter can be classified based on its physical state, composition, and properties.  BY PHYSICAL STATE: Solids, Liquids, Gases, Plasma, Bose-Einstein Condensate BY COMPOSITION: Pure Substances (Elements and Compounds) Mixtures (Homogeneous and Heterogeneous) BY PROPERTIES: Physical Properties Chemical Properties ESSENTIAL QUESTION: How does understanding the methods of classifying matter impact our ability to solve problems, and apply scientific knowledge effectively in everyday life? FLOWCHART: COMPLETE ME! cannot be can be separated MATTER separated physically physically Pure Mixtures Substances cannot be separated chemically cannot see the parts Elements Homogeneous Compounds Heterogeneous can be separated chemically can see the parts CLASSIFICATION OF MATTER ▪ Pure Substances – substances that have constant composition and properties (contain only one kind of particle) ▪ Elements – substances composed of only one kind of atom. They can be classified into metals, nonmetals, or metalloids. ▪ Compounds – substances composed of two or more kinds of atoms that are chemically bonded together in fixed proportions. They can be classified as acids, bases, or salts. CLASSIFICATION OF MATTER CLASSIFICATION OF MATTER  Some Common Elements It is considered as the lightest CARBON element. It is one of the most abundant COPPER elements in the universe. It is found in toothpaste in the HYDROGEN form of fluoride, which can help prevent dental cavities. FLUORINE It is one of the first metals used by man.  Some Common Elements It is one of the most abundant POTASSIUM metals in the Earth’s crust and can be recycled several times. It is a very reactive metal that is ALUMINUM never found free in nature. MERCURY It is a metal that exists in a liquid state at room temperature.  Some Common Elements It is a yellowish nonmetal GOLD usually found in volcanic vents. It is a metal that is used to SILVER make jewelry. NEON It has the highest electrical conductivity among metals. SULFUR It is a noble gas primarily used to light up advertising signs or displays. CLASSIFICATION OF MATTER ELEMENT + ELEMENT = COMPOUND Some Common Compounds CLASSIFICATION OF MATTER ▪ Metals – constitute the greatest number of elements in the periodic table. They are located at the left part, the middle part, and the bottom part (the lanthanide and the actinide groups) of the periodic table. These elements have characteristics that are distinct from the other elements. CLASSIFICATION OF MATTER CLASSIFICATION OF MATTER ▪ Nonmetals – are elements that lack or do not have the characteristics of metals. They are located at the rightmost part of the periodic table, except the hydrogen, which is at the leftmost part. ▪ Metalloids – are elements which have the properties of both metals and nonmetals. They are located between the metals and nonmetals forming a staircase pattern on the periodic table. CLASSIFICATION OF MATTER ▪ Acid – is a compound that donates H+ ions in an aqueous solution. It tastes sour and turns blue litmus paper to red. ▪ Base – is a compound that accepts H+ ions in an aqueous solution. It tastes bitter and turns red litmus paper to blue. ▪ Salt – is a compound that is formed when an acid and a base react. This reaction, which forms salt and water, is called neutralization. CLASSIFICATION OF MATTER ▪ Mixtures – are made up of two or more substances which are mixed together but are not chemically combined. ▪ Homogeneous Mixture – has only one phase and a uniform composition all throughout. ▪ Heterogeneous Mixture – has two or more phases. It does not have a uniform composition. ASSIGNMENT BRING THE FOLLOWING MATERIALS: - red litmus paper - coffee - blue litmus paper - toothpaste - small cups (10 pcs) - oil - lotion - dishwashing liquid - calamansi - vinegar - soy sauce - soapy water - cologne QUIZ! ▪ Multiple Choice (5 items) ▪ Identification (5 items) ▪ Essay (5 items)  GROUP ACTIVITY! C – CLAIM E – EVIDENCE R – REASONING C – this sentence should answer the question you are writing about E – this sentence should include evidence from a text or from experiences that support your claim R – the reasoning explains how your evidence proves your claim, you should restate your claim.
