Magical Drawing (Physics Experiments)

Have you ever wanted to create something that blended art and science? Well, here’s your chance! In this experiment, you’ll get to construct a drawing that has moving parts. The parts, however, aren’t magical-just magnetic.Things Required:Two poster boards or stiff cardboardsBox of crayonsMarkersTapeA bunch of metal paper clipsPair of scissorA small magnetDirections:Draw a colourful setting …

Floating Magnets or Anti-gravity Discs (Physics Experiments)

The title probably did get your attention. These discs appear to float in mid-air. Their secret isn’t an anti-gravity formula handed down by aliens from UFO’s. It’s just a result of magnetic repulsion.Things Required:Four magnets with holes in their centre (available at local electronics stores)6-inch-long wooden dowelFlat wooden baseCarpenter’s wood glueDirections:Cut a piece of 1/4-inch …

Stethoscope (Physics Experiments)

A physician’s stethoscope is a sound-capturing device. Its sound gathering end is formed by a flat drumhead. Sounds detected by this surface are transferred through the hose to the broadcasting end of the tool. There, vibrations leave the tube and are detected by the physician’s ear.Things Required:Two funnels1-foot-long plastic tubingDirections:Slip each end of the plastic …

Attractive Shapes (Physics Experiments)

Water has a skin-like covering formed by the way water molecules attract one another. This attraction is called surface tension. Objects such as needles and pins float effortlessly on this invisible skin. Needles and pins are also easily magnetized. Perhaps we can combine these characteristics.Things Required:A dozen sewing needles or pinsMagnetNon-metal bowlWaterMetal paper clipDirections:Magnetize about …

Needles Pointing North (Physics Experiments)

Two thousand years ago, Chinese navigators figured out how magnets could be used in navigation. Some people believe this connection was discovered when someone dropped a piece of natural magnetic rock (called lodestone) into a bucket of water. The rock settled so that it might “point” to north. Every time it was dropped, the rock …

Centre of Gravity (Physics Experiments)

Where is the centre of gravity of an object? This is what we are going to reach for in this experiment.Things Required:Paper hole punchPush tackWasherString, 12 in. (30 cm)ScissorsManila folderRulerTack boardDirections:Cut one side of the manila folder into an irregular shape. Punch four randomly spaced holes in the edge of the paper with the paper …

Generating Electricity (Physics Experiments)

So far, the electricity you’ve generated has been produced by chemical reactions. Although this source of electricity is important yet most of your home is supplied by electricity that has been produced by generators. Generators are large devices that change the energy of spinning magnetic fields into electric current.Things Required:Strong bar magnet10 yards of 24-gauge …

Pitch Switch/ Making Ektara (Physics Experiments)

Slide your fingers along the neck of a guitar and you’ll feel ridges. These ridges divide the neck into distinct regions called frets. When the string is pressed, its vibrating length is determined by the nearest fret. Frets closest to the sound hole produce the highest notes. Frets farthest from the sound hole produce notes …

Hanging Hammer (Physics Experiments)

This experiment is almost magical in nature. The purpose is to demonstrate that the centre of gravity is the balancing point of an object.Things Required:Yardstick (metre stick)Hammer (wooden handled hammer works best)String, 12 inches (30 cm)Directions:Hold the ends of the string together and tie a knot about 2 inches (5 cm) from the ends. Insert …

Battery of Cells (Physics Experiments)

A single cell made of two metals can produce only a small “push” of charge. To increase this push, several cells can be wired together. This arrangement of side-by-side cells forms an electrical device known to scientists as a battery.Things Required:Three copper coinsThree iron washersSteel woolBlotter paperPair of scissorsSaltWaterCurrent meter (assembled in “Simple Multimeter”)Directions:Polish the …
