Who Am I? Who Am I?

"I stated the law that ‘if pressure is applied at any one point in an enclosed liquid, that pressure is equally transmitted in all directions within the liquid.'" Who Am I?

How this activity helps?You learn the science behind how some everyday objects work. Your curiosity is triggered.

How Each Works?How Each Works?There are some common everyday objects on one side. The principle behind how they work on the other. But they are all jumbled. Match the objects to the science behind them.

Cooling through evaporation

Air pressure

Mechanical pressure

Mechanical instrument powered by electricity

Answer : Cooling through evaporation, Air Pressure,Mechanical pressure, Mechanical Instrument powered by electricity

How this activity helps?Your observation and visual tracking skills are enhanced.

You observe how a hydraulic bridge works.

Hydraulic MazeHydraulic MazeHydraulic bridges are bridges that move to allow passage for boats/ships. These bridges are powered by hydraulic pistons or electric motors. So, here is a boat that has to pass through this hydraulic bridge maze. Help the boat reach its destination.

How this activity helps?You understand the difference between the concepts of pneumatics and hydraulics.

You gain practical knowledge.

Hydraulics Or PneumaticsHydraulics Or Pneumatics

The branch of engineering that uses gas or compressed air is called pneumatics. For eg: brakes in a bus.

The use of liquids to perform mechanical tasks is called hydraulics. For eg: dump truck lift.

Look at the illustrations to identify which machine works on pneumatics and which works on hydraulics. Cut, sort, and paste them in the following sheet.

How this activity helps?You understand the basic structure of a hydraulic crane. Your curiosity increases.

Hydraulic Crane Hydraulic CraneHydraulic cranes work with the principle of transferring force from one point to another, using fluids.

Join the dots to complete the hydraulic crane and colour it.

How this activity helps?Your visual tracking skills improve. Your vocabulary in this concept is enhanced.

Word MazeWord MazeThere are words hidden in this word maze. Look horizontally, vertically, and look across to find them. Clue: All the words are all related to hydraulics.
