The goal of the experiment:    Determination of the volume of a solid body given the volume of a liquid Experience Tools: Graduated Tester - Water - a group of solids of different size Steps of the experiment: Water the test with 50 cm3 of water. - Put the solid objects in front of you in......

The goal of the experiment This experiment aims to practically determine the density of a liquid. Experiment Tools Scale - Included tester - different liquids with different volumes Steps of the experiment Choose a few different sized liquids from the lab library. Weigh the tester blank inserted and......

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......

Hydrometer Experiment to Measure Liquid Density

Archimedes' Principle | Buoyant Force

how the type of material affects the change in temperature of objects.

Shape and Flowability of States of Matter

Effect of Viscosity on the Movement of Objects in Liquids

Experiment on Volume and CompressibilityVolume is the amount of space that matter occupies in the universe. Compressibility is the ability of a substance to reduce its volume when subjected to external pressure. Liquids and solids have nearly fixed volumes, while gases are the most compressible subs......

Mass of matter

This experiment aims to observe the effects of weightlessness during free fall.

Experiment that demonstrates the Law of Conservation of Mass.

Objective: To understand the role of air in helping objects float on water.Materials: Balloon – beach ball – football – plastic bottle half-filled with water – plastic bottle almost full of water – container filled with waterSteps: Prepare a container filled with water and place it on a flat surface......

Objective: To investigate the effect of a soft drink on an iron nail and observe the changes that occur over timeMaterials: Iron nail – glass cup – soft drinkSteps: Observe the appearance of the iron nail before starting the experiment Pour enough soft drink into the glass cup Drop the nail into the......

Objective: To identify materials that dissolve in water and materials that do not.Materials: Three transparent cups _ Water _ Salt _ Sugar _ Sand _ Stirring spoonSteps: Put some water in each cup. Add a small amount of salt, sugar, and sand to the three cups of water. Stir each cup using the spoon a......
