Science Fair Project for 6th Grade
This video is about science fair projects for 6th 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.
