Energy from Food Materials Required: Food labels, books, other research materials Paper and pencil Like all appliances and other objects, even the human body needs energy and this energy comes from the food that we consume. Energy that we need is measured as “calories”. Our body needs its daily dose of calories to function properly and to keep us healthy. Different occupations of people ensure that they need different calorie intakes....

Heat Energy Materials Required: Toy Pinwheel Pyrex Beaker Stove Burner One-hole rubber stopper Glass tube bending at 90° Gas converted from water through heat energy is called Steam. This steam can be used for many processes, like in the case of power energy for boats and trains. Electricity can be generated through steam turbines, when the produced steam pressure pushes against the blades which are connected to a shaft. This shaft...

Energy to Germinate Materials Required: Three different types of seeds Potting soil A closet or a basement Three small containers Masking tape Pencil and paper A seed is a storehouse of energy, which is used by a plant to feed itself. When a seed is planted, it grows roots and leaves, with the help of which it makes its own food. The root of the seed digs into the soil and...

Using Electricity Materials Required: Arts and crafts supplies With Thomas Edison’s discovery of the electric bulb, towns and cities got a new look completely. This was because of the entry of electrical power into the design of the city. Cover the whole city and think about how the city would have perhaps looked, without all the electric accessories, like the light posts and wires. Would the lit-up signposts be there? The...

Understanding Nuclear Fission Materials Required: Dominoes A ruler A flat table When the nuclei of atoms are combined (called Fusion) or split (called Fission), energy is formed. This is known as Nuclear energy, which is released through heat, light or some other radiation. Nuclear energy is generally used to produce electricity by converting water to steam, thereby operating huge turbine generators. The process of nuclear fission causes a chain reaction. Uranium...

Energy in Moving Water Materials Required: Sand Four two/litre plastic bottles Water Model houses and buildings A large dish pan Several thick books Piece of still cardboard of about 2 by 4 feet Plastic food wrap Adhesive tape During hurricanes, places next to the beach are always destroyed. This is caused by the wrath of the ferocious kinetic force of moving water.  For the experiment, cover an area of around 2...

A Water Turbine Materials Required: A Cork A Knitting Needle Four thin pieces of plastic Proximity to a tap Bore a hole through the center of a cork and insert a knitting needle through it. Make six slits on the surface of the cork and wedge thin slices of plastic into each slit. Hold the turbine under a steam of water. The turbine rotates as the water hits the vanes. The...

Different Temperatures Materials Required: A thermometer A watch Paper and pencil Since the heat energy in a room is not equally distributed, different places in the same room have different temperatures. Select a few different locations in the room. They should be completely different from each other. For instance, you can select high places as also low ones, inside and outside walls, so that you get a clearer picture. Prepare a...
