Three states of matterThis experiment shows how water changes between its three states due to temperature. Ice melts when heated to become liquid water, then turns into vapor with continued heating. When the vapor touches a cold surface, it condenses back into water droplets.states of matter – solid......

Objective To determine the concentration of an unknown solution through an acid-base reaction using the equivalence point.Tools Beaker – burette – burette stand – unknown acid or base solution – standard solution of known concentration – suitable indicator – graduated cylinderSteps Place a measured......

Objective: To explore the ability of different materials to insulate and reduce sound by comparing sound levels after using various insulating materials.Materials: Different insulating materials (such as paper, bubble wrap, blanket). Sound source. Box with a lid. Sound level meter.Steps: Place the s......

Objective:Identify the effect of the reaction of reactive metals with hydrogenMaterials:Glass beaker – Water – Lithium – Sodium – Potassium – Tongs – Thermometer – Phenolphthalein solutionProcedure:Fill three beakers with equal amounts of water Add a few drops of phenolphthalein solution to each bea......

Objective:Learn how the Hofmann apparatus works and use it to electrolyze water into hydrogen and oxygen gases, while observing the amount of gas produced at each electrode.Materials:Hofmann apparatus – Electrical power source battery – Water – Dilute sulfuric acid H₂SO₄ – Dropper – Connecting wires......

This experiment aims to determine the density of solid objects by measuring their mass and volume. The mass is measured using a balance, while the volume is determined either from the object’s dimensions (if it has a regular shape) or by water displacement in a graduated cylinder (if irregular). The......

Objective:Demonstrate the importance of air entering and hot gases leaving in maintaining the combustion process.Materials:Candle – Piece of clay – Metal cover – Bottomless glass container – Candle holder – Wooden board – LighterProcedure:Secure the candle on the piece of clay placed on the wooden b......

Objective:Detect the carbon dioxide gas produced by burning the candle using clear limewater.Materials:Two glass containers – Two lids – Candle – Candle holder – Clear limewater – Safety goggles – LighterProcedure:Place equal amounts of clear limewater in the two glass containers Place the candle on......
