Teaching Science in the Elementary Grades EED006  Part 1 : Chemistry Lesson 1: Solid, Liquid and Gas  Objectives 1 2 Describe characteristics Classify objects and of different objects materials as solid, liquid based on the shape and and gas according to the scope they occupy some observable characteristics (PT)  Engage 1. What will happen to the paper towel inside The glass when It will be submerged upside down in the basin of water? 2. Will the paper towel inside the glass stay dry for a long time? Why? (PT)  Explore Let us try the following activities: Activity 1: Describe the Object's Shape and Space Occupied Activity 2: Classify Objects and Materials into Solid, Liquid and Gas (PT/L)  Explore Step 1 Q1. Press each objects A, B, C. Did the shape of objects A, B, and C change? Q2. Did the size of objects A, B, and C change in the three different containers after shaking? Q3. The objects in step 1 are all solids. Based on your observations, what can you infer about the shape and volume of a solid? (PT/L)  Explore Step 2 Q1. Did the shape and space occupied by the colored water change when placed in the different containers. Q2. From your observations of liquid colored water, what can you infer about the shape and colume of a liquid? (PT/L)  Explore Step 3 Q1. Describe and explain the shape of the air inside the round and elongated balloon. Q2. What happened to the air inside the balloons when these were untied. Q3. Air is a mixture of a gases. From your observations in step 3, what can you conclude about the shape and volume of a gas? (PT/L)  Explain All objects on earth can be classified in one of the three physical forms or states such as solid, liquid and gas. Solid - definite shape and definite volume. It keeps its own size Liquid - keeps its size but takes (PT/L) the shape of its container  Explain Gas - can freely change its shape and size. It spreads out to fill its container. Gases flow like liquids. They are very light and often they cannot be seen. (PT/L)  Elaborate 1. Make a list of objects or materials that you see at home, in school, in your environment. From the list identify 10 solids, 10 liquids, 10 gases, and 10 objects which you are in doubt of its classification. Make an explanation for your grouping. You may follow the table format below. (PT/L)  Evaluate (PT) Answer the questions below. 1. What is the best way to teach the concept- state of matter to let students have a first-hand experience and make them understand better? 2. What state of matter,matter do you consider difficult to teach? Why? (PT)  Evaluate (L) Part A. Choose the letter of the correct answer. 1. Which is true about solids? A. Solids cant be seen B. Solids occupy space C. Solids do not have a definite shape D. Solids follow the volume of its container. 2. Which among the given statements is NOT correct? A. Solids have different colors B. Gases cannot be compressed C. Solids, liquids, and gases occupy space (L) D. Liquids take the shape of their containers Questions?
