Work & Energy

Make a trebuchet to understand:

• Factors affecting gravitational potential energy possessed by an object due to its position

• Factors affecting elastic potential energy possessed
by an object as a result of deformation

• Potential and kinetic energy and their interconversion.

• Law of conservation of energy

Coordinate Geometry

* Rock your brains with challenging exercises to establish the need for a co-ordinate system

* Play the battleship game to practice representation of
points in the coordinate system

* Learn how to visualize the coordinate system - find the
point for the given coordinates and vice versa

* Practical applications of the coordinate system

Applications of Trigonometry

• Make a heights and distances model with an observer’s
view and a building, to observe various scenarios
encountered in problem-solving. Verify trigonometric ratios.

• Understand the concept - of angle of elevation and angle of
depression.

• Make a hand-held Theodolite instrument to determine
the angle of elevation or depression of any point from the
horizontal and calculate the height of an object from the
ground

Magnetic Effects of Electric Current - DC Motor

* Make a straight conductor and observe its magnetic effect on a compass

* Make a circular conductor and observe its magnetic effect on a compass

* Make a solenoid and find the direction of magnetic field in and around it using a compass

* Make a working model of a DC motor and understand its working

Heredity & Evolution | Biology

Trace the body of a wolf to understand:

• How characteristics are inherited from parents to offsprings?
• Using punnet square to find out all possible outcomes in inheritance

Play a strategy game “Survival of the fittest game” and breed your own monsters to understand:

• Dominance and co-dominance genes,
• How the dominant gene changes based of different circumstances
