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 ...

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 ...

ELECTRIC CHARGES

Image
TYPE OF CHARGES  There are two type of electric charges, positive charge (+) and negative charge(-) PROPERTIES OF ELECTRIC CHARGES Unlike charges, always attract each other.  Positive charge kept near negative charge/ negative charge kept near positive charge, attract each other. Like charges always repel each other.  Positive charge kept near positive charge / negative charge kept near negative charge, repel each other. PRESENCE OF CHARGE IN MATTER All the materials around as are generally known as matters (matter is anything that can occupy space and have mass). All the matters are made up of tiny building unites called atoms. Atoms are made up of some small subatomic particles – electrons, protons, neutrons. The centre part of the atom is known as nuclear , which contain protons and neutrons . Protons are positively charged particles and neutrons are chargeless particle (neutral). And electrons which are revolving around the nuclear of an atom in fixed orbits has neg...
