Term 2 Topic 1 Arrangement of Particles IntroductionAll matter (solids, liquids and gases) is made up of particles.The particles are arranged differently in solids, liquids and gases:in solids, the particles are closely packed in a regular pattern – spaces between the particles are small and particles vibrate in one place;in liquids, the particles are closely packed in no fixed pattern – spaces between the particles are small, but particles can move around each other;in gases, the particles are far apart from each other – spaces between the particles are big and particles move in all directions.Teacher Input 1Greet the learners.Show learners blocks of ice that you have taken out of the school freezer and placed in a transparent Tupperware / glass.Ask learners what is going to happen to the ice blocks if you leave the containers on your table.Answer: It will melt. It will turn into water.Tell the learners that we are going to talk about solids, liquids and gases today.Tell them that you are now going to show them a video clip.Show VIDEO CLIP 1: Ice Skater falls through ice (0:9 min.).Lead a discussion on why the ice skater fell through the ice. What happened to the ice?Answer: It melted; It changed from a solid state to a liquid state.Present an overview of the three different states of matter by using PRESENTATION 1: Solids, liquids and gases.Show VIDEO CLIP 2: Solids, liquids and gases (3:00 min.).Learner Activity 1In this activity, learners are going to mimic the particles in solids, liquids and gases.Divide the class into three groups.Provide each group with the following instructions –Solid:You are the particles in an ice cube (a solid).Sit or stand as closely as possible, touching each other, in neat rows.Move your body, but not your feet.Liquid:You are the particles in a glass of water (liquid).Move around, but stay in contact with each other all the time.Gas:You are the particles in helium (gas).You should now move around and be as far from each other as possible.If you touch each other, move away immediately.Teacher Input 2Encourage children to consolidate what they have learnt about the three states of matter by singing (and learning) a fun song.Show VIDEO CLIP 3: States of matter (1:39 min.).Learner Activity 2Learners complete WORKSHEET A: Solids, liquids and gasesGuide learners on how to undertake this activity and how the worksheet will be assessed.Teacher to use WORKSHEET A: Memorandum to mark the learners’ work.Learner Activity 3Place the following (or similar) containers where learners can easily see them in the classroom -cool drink bottleballoonglass jarcuptea potpacket (in which rice has been stored)a coffee tinLearners complete WORKSHEET B: Three states of matter in everyday life.Guide learners on how to undertake this activity and how the worksheet will be assessed.Teacher Input 3Draw the following pictures on your blackboard – without the 3 headings (gas, liquid and solid)Ask learners to:identify the type of matter of each drawing;list the characteristics of the particles of each matter.To consolidate their understanding, show learners VIDEO CLIP 4: Particles are moving (2:58 min.).Repeat demonstration in Video Clip 4 by lighting an incense stick in the class room. Let learners explain what they observed.Learner Activity 4Learners complete WORKSHEET C: Arrangement of particles in different types of matter Guide learners on how to undertake this activity and how the worksheet will be assessed.Teacher to use WORKSHEET C: Memorandum to mark the learners’ work.Revision Activity 1Learners complete QUIZ 1.Guide learners on how to undertake this revision activity and how the quiz will be assessed.Teacher to use QUIZ 1: Memorandum to mark the learners’ work.
