Here is a beautiful science project for primary school kids. I would strongly suggest elders to be with kids in carrying out this project.
You need 2 battery cells, a small D.C. motor of 1.5V, 2 litre plastic water bottle, cork, icecream stick, gum tape, scissors, wire and gum.
Join 2 battery cells of 1.5V each with the help of elastic and gum tape. Attach copper wires to its
positive and negative terminals. Connect the end of any of these two wires to a toy motor.
Take two meter long insulated copper wire. Remove the insulation at both its ends. Connect one end to the motor.
Take another long insulated wire and connect one of its ends to the battery. See that the circuit is complete. If all your connections are proper, the motor should rotate.
Take a two litre water bottle and cut a rectangular flap on one of its
sides as shown in the figure. If the sides are very sharp, stick tape.
Fix the battery inside the water bottle.
Fix the motor to the mouth of the water bottle. Its central axis should be facing outwards. Stick tapes around the motor and the mouth of the bottle to prevent water from entering in.
Fix a 1 cm thick cork to the axis of the motor. It should rotate freely on its axis. Take an icecreams stick, apply
paste to its centre and fix it to the cork. Let it dry up well. This will act as the propeller of the boat. The length of the stick can be cut down later if it overturns the boat while moving.
Introduce a simple switc
h into the circuit. You can even fix a bulb inside the boat and light it.
Instead of icecream stick you can use the propeller of some old toy.
Fill a tub with water. Allow your boat to sail on water. You will enjoy this science project. Find out as to how the boat sails on water.
