Understanding Rechargeable Batteries: An Experimental Approach

This lesson explores rechargeable batteries through a hands-on experiment comparing their performance in a light bulb and a motor. Students will formulate a hypothesis on battery function, conduct an experiment to measure the light bulb's lit time versus the motor's running time after a 3-minute charge, and analyze their findings. Important vocabulary terms, such as 'rechargeable battery,' 'dry cell,' 'wet cell,' and 'electrolyte,' will be integrated into the experiment to enhance understanding. Conclusions will be drawn using complete sentences.
