PETA 4 in Science 6Activity: "Make Your Own Suspension"ObjectiveTo help students observe and understand the properties of suspensions by creating their ownMaterials:Clear plastic cups or beakersWaterSand, flour, or dirt (for creating the suspension)A spoon or stirrerA stopwatch or clockInstructions:Step 1: Fill a plastic cup halfway with waterStep 2: Add one teaspoon of sand (or flour, or dirt) to the waterStep 3: Use a spoon to stir the mixtureStep 4: Set the mixture down and observe what happens to the particles in the water Use thestopwatch to time how long it takes for the particles to settle to the bottom.Step 5: Ask the pupils to describe what they see. Are the particles dissolved? Do they stay mixed, or dthey settle? What does this tell us about suspensions?Discussion Questions1. What happened to the sand or flour after you stirred it into the water?2. How is this different from when sugar or salt dissolves in water?3 Can you think of other examples of suspensions in everyday life?Extension ActivityAsk students to research and draw another example of a suspension they can find at home (e.g.orange juice with pulp or salad dressing).This activity is simple, and engaging, and allows students to see the properties of suspensionsfirsthand. Let me know if you'd like to adjust any part of it!NOTE 1 Have a picture while doing the activity and paste it on a long bond paper (PETA PAPER)2. Answer the discussion Questions3.
