                                    Science Fair Project for 6^th Grade

This video is about science fair projects for 6^th grade. This project is making a lemon battery.

Materials Required: –

• Two lemons
• Two pennies
• Two galvanized nail
• Multimeter
• A sharp knife
• Copper wire

Procedure: –

• Roll the lemon on the table so that it can get charged. It breaks the cell walls and loosens up the juice.
• This sour juice is required for the chemical reaction which is going to take place.
• Cut a ½ inch deep slit in the lemon using the knife.
• Insert the penny in the slit. You can also use copper wire if you want.
• Insert the galvanized nail at another end of the lemon in a way that the penny and the nail must not touch.
• Now one cell of your lemon battery is ready and you can take the reading by using the multimeter.
• Make one more sell using the same way.
• To create a battery of higher voltages we can connect two or more cells.

Concept: –

The energy we get from a battery comes from chemical energy. The chemical energy gets converted into electrical energy. This lemon battery is a voltaic battery. Here, the penny and the galvanized nail are working as electrodes.
