TYPE OF MIXTURES



 Mixtures are classified based on the components that form a mixture, its compositions etc. Mixtures are of two types homogeneous mixtures and heterogeneous mixtures 


HOMOGENEOUS MIXTURES 

Mixtures which have uniform composition throughout are called as homogeneous mixtures.
Examples 
  • Salt dissolved in water
  • Sugar dissolved in water 
  • Copper sulphate powder dissolved in water 

HETEROGENEOUS MIXTURES

Mixtures which have non-uniform compositions and contain physically distinct parts are called as heterogeneous mixtures.
Examples 
  • Cornflakes Mixed with milk
  • Mixture of sodium chloride and iron fillings
  • Mixture of oil and water

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 ...

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...

MAGNETS

Image
Magnets are substances which can attract some materials like iron, steel, nickel etc.  Different types of magnets  Based on shape of the magnets we can classify magnets into different names. Pictures and names of som magnets are given below                   A magnet always has 2 poles a north pole and a south pole ( when a magnet is cut into two pieces, the new pieces formed will act as separate magnets with a north pole and south pole for each
