HOW TO DISTINGUISH BETWEEN BOILED EGG AND RAW EGG

 





If we are provided with two egg where one is boiled and other is raw, can you identify them without breaking the shell?

Place eggs provided in plane surface try to rotate both of them using your fingers, you can observe one of the egg rotate fast and more time that the other egg. 
The egg which rotate faster and more time is the boiled egg and one which rotate slowly in less time is raw egg. It’s because raw egg has fluid inside it which resist the rotation and boiled egg is in solid form, in which inertia of rotation is comparatively high so boiled egg can rotate faster for more time than the raw egg.

COLLOID

Image
  In colloidal solutions particles are uniformly spread throughout. Due to small size of particles, colloids appears to be a homogeneous mixture but it is a heterogeneous mixture. A colloid contains a dispersion phase and a dispersion medium. Dispersed particles in colloid is known as dispersion phase and component in which dispersion phase is suspended is known as dispersion medium. Colloids are classified based on difference in state of dispersion medium and dispersion phase. Type of colloids with examples is provided in the below table, Examples of colloids  Milk, jelly, shavings cream, smoke, foam, mud etc Properties of a colloid Colloid is a heterogeneous mixture  Particles of colloid is small, cannot be seen with naked eyes  Particle size of colloids are big enough compared to pure solution to scatter a beam of light, so that we can observe Tyndall effect. ( The phenomenon in which path of a light is visible when a beam of light passed through some colloids is ...

ACCELERATION

 Acceleration is defined as rate of change of Velocity.  Ie, acceleration = change in Velocity/time Consider a body moving with an initial velocoty(u) reaches a final Velocity (v) in time (t). Hence velocity is charged from u to v at time t  body is accelerating. Acceleration ( a ) = change in Velocity/ time a = v - u/t Unit of acceleration is m/s² There are two types of acceleration  1. Positive acceleration  If the Velocity of a body is increasing with respect to time(body is increasing the speed) then the acceleration is considered to be Positive.  2. Negative acceleration (retardation) If the Velocity of a body is decreasing with respect to time ( body is reducing the speed), then the acceleration is considered to be negative.  It's also called as retardation.

WORKING MODEL FOR SCIENCE EXHIBITION- DANCING BALLOON

Image
 DANCING BALLOON  SCIENCE EXHIBITION PROJECT FOR HIGH SCHOOL STUDENTS  A working model for science exhibition ‘THE DANCING BALLOON’ is an application of Newton’s third law of motion- Every action has an equal and opposite reaction and also explains about effect of less friction helps in the motion of a body. MATERIALS REQUIRED  1- Balloon  2- Compact disk (CD) 3- Glue 4- Bottle cap PROCEDURE  *Put a hole on bottle cap(at the centre)  * Using glue stick the bottle cap at the top of CD (cap should be fixed on rough and non shiny surface of CD . Make sure no gap between CD ad the bottle cap) * Keep it aside still glue dries up to make strong bond between CD and bottle cap * Inflate the ballon and fix it on bottle cap as shown in video  * And keep CD on plane surface and release it. RESULT Balloon/CD arrangement start moving around the plain surface automatically . SCIENTIFIC EXPLANATION  Due to the force applied by the air inside the balloon it ...
