SUSPENSION

 A suspension is a heterogeneous mixture of two or more substances in which solute particles do not dissolve but remain Suspended through out the bulk of the medium.

Examples of suspensions

  • Mixture of sugar and stones 
  • Mixture of oil and water
  • Mixture of iron fillings and sand
  • Mixture of copper sulphate and potassium permanganate 

Properties of suspension

  1. Suspension is a heterogeneous mixture.
  2. The particles of suspensions can be seen by naked eye.
  3. The particles of a suspension scatter a beam of light passing through it and make its path visible.
  4. The solute particles settle down when a suspension kept undisturbed. When particles settle down, the suspension breaks and it doesn’t scatter light any more.
  5. Suspension can be separated from the mixture by the process of filtration.

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
