Description
Month-1: Light & its Mysteries
Kaleidoscope:
Make your own Kaleidoscope and understand:
• Symmetry through reflections in mirrors
• How patterns are created by multiple reflections.
Do an exercise using a plane mirror to find lines of symmetry of different shapes
Shadow Projections:
Build a model with a light source, object and screen to understand:
• How shadows are formed?
• Know the effect of changing object distance on size of the shadow formed
Build a model to see how change in angle of light changes the length of the shadow formed
Identify the shape of the object by seeing its shadow
Month-2: Solar System
Natural phenomena – phases of moon:
Make different models to understand:
• Formation of days & night
• Formation of different phases of moon
• Formation of eclipses
Earth is oval!
Make a model of earth, sun and moon to understand difference between rotation and revolution.
Make a model of earth and observe the effect of rotation on it that gives earth an ‘egg’ like shape.
Month-3: How Stuff Works
Air around us – Vacuum Cleaner:
Build the model of a miniature vacuum cleaner to understand:
• Air can push as well as pull things – using fan
• Real life application of properties of air
• Air is present everywhere and lack of it leads to sucking of things.
• Introduction low pressure and high pressure (HOTS)
• Make a mini shooter and a balloon balance to understand that air can exert force and air has weight.
Introduction to force:
Make a parachute to understand:
• Air drag and gravity as forces.
• Relationship between weight of the person and size of the parachute.
Solve a maze puzzle using magnets
Create static charges by rubbing different materials to experience electrostatic force
Do a series of experiments to see effects of a force applied on a object
Month-4: Simple Machines
Simple machines – Levers:
Make class 1 and class 2 levers and understand how they help ease our efforts.
Compare the working of a forcep (class 3 lever) with that of the other 2 to understand the difference in position of load, effort and fulcrum.
Inclined plane, wedge:
Make an inclined plane to lift objects. Observe the reduction in effort when the angles are changed however there is a trade off – can you spot it?
Make a wedge and how it reduces effort. Understand that relation between wedge and inclined plane.
Month-5: All About Seeds
Seed dispersal:
Make models to understand different seed dispersal mechanism – Air – Maple seeds, Animals – Squirrel and hazel nut, drop and roll – passion fruit, Shakers – poppy seeds and hitch hiking.
Plants – Pollination:
Make models and play a game to understand how bees and butterflies help in cross pollination.
Understand self pollination.
Month-6: Air & Water
Hydraulic canon (Air & its properties):
Carry out a series of experiments to understand different properties of air:
• air occupies space & has weight – Balloon balance
• air can push things – Hydraulic canon
• air (oxygen) is needed for combustion – Water candle experiment
Rain water harvesting:
Make houses with different roof tops ( slant and flat) to understand:
• Chanelling mechanisms for flat and slant roofed houses
• Collection pit
Make a water pump to understand the the complete mechanism:
• Collecting rain water (roofs) – Storing ( in a sump) – and then retrieving (using a pump).
