Hypothesis If the amount of water is increased the pitch gets lower. I can make music with the bottles of water. Materials needed eight glass soda bottles of the same size and shape water paper slips numbered 1 to 8 pencil Procedure Pour water to different levels in the bottles. Blow gently across the…
When a drop of wax falls down on one side, the candle looses its balance and preponderates to the other side. There the flame grazes the candle, so that a drop of wax falls down also on this side. Candle looses its balance again and preponderates back again. So the candle swings until it runs…
How to Make a Hang-Glider For hang glider making you will need a sheet of A4 photocopy papersome paperclips. Method Fold the sheet in half across its narrowest part (its width). Paperclip both thicknesses together near the fold.Curl the halves of the paper outwards and downwards. Then clip together the corners A and B -…
Inertia of an Egg Topic: To demonstrate the Inertia of an Egg. Materials Required: 1. Raw & boiled eggs 2. Glass plate Procedure: A dozen eggs are placed on a glass plate and one of them eggs is hard-boiled while the rest are raw. How can you find the hard-boiled egg without cracking the shell…
Sucking a balloon into a flask Level: Elementary/Secondary Concept: When water vapor in a frank is cooled and condensed into water drops, the pressure in the flask reduces greatly. Introduction: When water vapor changes into water drops,its volume reduces to less than one thousandth.Using this principle, we can make a virtual vacuum and let a…
in activity you learned about center of gravity. What is role of center of gravity with the nail balancer why don’t the overhanging nails tip the system over? Did you ever see a tightrope walker? They usually carry a low bending pole. Can you see a similarity with the nail balance? Do some research about…

How to Make a Tornado in a Bottle Tornadoes are formed when warm, moist air swirls together with cool, dry air. They are most often associated with storm clouds that contain vortexes — spirals of rising air. As the vortex sucks in the surrounding air, more air moves in at a high speed to fill…
How To Make Hot Air Balloon To make Hot Air Balloon is an interesting and worth learning activity to learn about the relationship between properties of gases, temperature and pressure. Concept When we heat the gas, its volume increases and it inflates. Let’s make easy balloon by using this phenomenon. Materials required Garbage bag (thin,…
Fleming’s Left Hand Rule Experiment, Electric current and magnets. Level Elementary. Concept When two magnets are close together, magnetic forces are at work. Two magnets repel or attract each other. A wire carrying an electric current and a magnet also repel or attract, because electric current makes a magnetic field. Materials solder wire enameled wire…
How to make capacitor with aluminium foil and paper How to make capacitor with aluminium foil and paper cup : A capacitor is a device for storing a small electric charge. When two conductive plates are separated by a small insulator called a dielectric, they produce an electric field. Aluminum foil is conductive while cling wrap…
