Rising Upwards Materials Required: Glycerin Water Pipe cleaner A toaster A small bowl Liquid soap A measuring cup A tablespoon An adult It is a known fact that hot air rises upwards. It was this principle of hot air, which in 1783, in France saw the first instance of a hot air balloon, rising to an altitude of 6,000 feet approximately. These hot air balloons were later used to carry weather...

Motion and Gravity Materials Required: An empty thread spool Some string Four small metal nuts Cotton Adhesive tape Scissors If you throw a ball up, it is pulled back under the influence of the force of gravity. However, this also proves that your throwing motion overcomes gravity for a short while. It is possible then for motion to overcome gravity. To prove this, attach three of the nuts that you have,...

Moving Energy Uphill Materials Required: A ruler Dominoes Have you ever wondered whether a wave of energy can move in an upward direction? It’s really very easy to find out. Take a long ruler and place two dominoes under it at one end, so that it can facilitate as a ramp. Now prop up a domino on the ramp, that you have constructed and see if it can stand up on...

Lifting Power Materials Required: Paper towel tubes Pencils with flat sides Rulers A hair dryer A table Scissors Two books of equal thickness The design of an airplane wing has a particular reason. The curve of the wing at the top causes the air travelling over it to travel a farther distance than the air that moves from below the wing. This mechanism makes the air move faster, causing a drop...

Gravitational Pull Materials Required: Modelling clay Cardboard Four rulers Two marbles of equal size Two marbles of different size A table An uncarpeted floor under the table Though the force of gravity has the same force for everything on the earth’s surface, have you ever imagined as to what would happen, if you were to drop two marbles at the same time, from the same height? Would there be any difference...

Flying Upward Materials Required: A flagpole A long or oblong balloon Two small paper clips Adhesive tape Some string A partner Isaac Newton had proposed a law in 1687, which stated that “for every action there is an equal and opposite reaction.” This law can be very easily explained. If you and your friend are standing at a point and your friend comes forward and pushes you, you will surely move...

Energy in Motion Materials Required: Marbles Two rulers Two books A rug A piece of paper When objects are in motion, they possess a kind of energy in them, which is termed as Kinetic Energy. Since all kinds of energy are transferable, similarly, when a moving object touches another object, then the Kinetic Energy is transferred from the first object to the second. For this experiment, take a rug and place...

Energy in Motion Materials Required: A ping-pong ball Masking tape Empty paper towel roll Measuring tape Rubber bands Board of measurement, 4 inches wide and 1 inch long Two nails A hammer Paper and pencil When a particular substance is stretched, it contains potential energy, which is the energy ready to do work. Once you let it go, this potential energy is converted into kinetic energy. To determine that a substance...
