## Science Project on “Rolling Backward”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.

Rolling Backward Materials Required: Two cardboard disks of about 3 inch (7.5 cm) An empty wooden spool Some strings Cut out the disks from a cardboard. Use glue to stick them to the ends of an empty wooden spool. Take the string and wrap some around the spool. Now pull the free end as in the illustration. The question is will the spool roll away? Come towards you or will it...

## Science Project on “Magnetic Forces”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.

Magnetic Forces Materials Required: A strong magnet Stapler pins Two glasses Two books A pencil A cylindrically shaped balloon A freezer A ruler An invisible form of energy, magnetism can actually pass through air. But the question is – can magnetism also pass through water? What is the essence of water as ice? Would that affect magnetic forces? To find out, fill a cylindrical shaped balloon with water. Remember that you...

## Science Project on “Inertia that Sticks”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.

Inertia that Sticks Materials Required: A matchbox A paper match A cylindrical cork Three impossible feats can be pulled off, if you can be a little sneaky. It is fun and a great source of entertainment for your friends. Consider these three feats: 1.Drop a matchbox from a height of six inches(15 centimetres) over a table top, so that it lands on its end and remains upright. 2.Drop a paper match...

## Science Project on “How to Defy the Gravity”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.

How to Defy the Gravity Materials Required: An empty plastic bottle A sharp pencil In a gravitational field, everything falls at the same speed, no matter what its weight is or what it is made of. Gravity disappears inside a free-falling container. This is one trick that should preferably be performed outdoors. Make two holes on opposite sides of a plastic bottle, near the bottom, with a sharp pencil. Fill the...

## Science Project on “Hanging a Bottle”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.

Hanging a Bottle Materials Required: A Coke bottle Uncooked rice Use the uncooked rice to fill a Coke bottle tightly. Insert a pencil, a chopstick or a rod along the neck of the bottle, into the rice. You will find that when you lift the pencil, the bottle comes with it! Chances are that you may need to try out several times, before it sticks in the rice. Give the pencil...

## Science Project on “Force Fields”, Project Experiment Topics on Electricity, Magnetism Gravity for Class 8, 9, 10 and 12 Students.

Force Fields Materials Required: An adult A hammer Safety pin Glass jar Magnet Thread Adhesive tape A magnet is an object surrounded by a field of currents and has the property of either attracting or dispelling metals, such as iron or steel. When you throw up an object in the air, the force of gravity pulls it down towards the earth. These two invisible forces are very strong, but which of...
