Please join us as we learn Science by exploring our world.

Charging a battery . We had a experiment on charging a battery . First we tried a light bulb , We charged the battery for 3 minutes and the light bulb lit for about .. 10 minutes ? Then the next day we charged the dead battery for 3 minutes and attached it to a motor and the motor ran for 7 minutes . Since the motor didn't run as long as the bulb that means the motor uses more energy . Motors use mechanical energy & light bulbs use light and heat energy !
