SOLUTION

 A solution is a homogeneous mixture of two or more substances.

A solution has a solvent and a solute.

  • Solvent- Component of solution that usually found in larger amount which dissolves the other component in it.
  • Solute - Component of the solution usually present in lesser quantity that is dissolved in a solvent 
Examples 
  1. Sugar dissolved in water. Where sugar is the solute and water is the solvent.
  2. Soda water if solution of carbon dioxide dissolved in water. Where carbon dioxide is the solute and water is the solvent.
  3. Tincture of iodine - a mixture of iodine and alcohol. Where iodine is the solute and alcohol is the solvent.

Properties of solution 

  • Solution is a homogeneous mixture 
  • Particles of a solution are very small they cannot be seen by naked eyes ( particle size is smaller than 1 Nanometer = 10−⁹ meter in diameter)
  • Because of smaller particle size they don’t scatter beam of light passing through it.
  • Particles of solution cannot be separated by filtration.
  • Solution is stable because solute particles don’t settle down when left undisturbed.

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 start moves automatically. ( air released th

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 negative charge.

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
