Conclusion
Do cordless phone batteries hold energy long term and could they be used to power technology? This test is testing for how long a cordless phone retains its power without use. If the time between charging and use is smaller, the motor will run longer. The independent variable is the time between charging and running the motor. The dependent variable is how long the motor runs.
The data shows that during the shortest periods of time, it ran longer. 2 data points are not in sync with the others because there was either cloud cover or probably a miscalculation on the time outside. The experiment would be set outside for 30 minutes, and then be brought inside to wait for the set amount of time before hooking it up to the motor.
The data fits the hypothesis because during the optimal conditions it ran longer with no wait time. The run with no wait time was the longest at 34 minutes until the steady decrease on the graph was interrupted by some “wonky” data. My results were expected except for the middle two data points. It is believed clouds and a wrong timing run caused those 2 samples that were out of sync.
The experiment relates to the ever-daunting problem of finding a reliable, affordable battery for an electric car. It is planned to test a variety of current electric car batteries for more results. Some of he batteries include: Nickel Cadmium, Nickel Metal Hydride, Lithium ion, and lead acid batteries.
This experiment tested whether cordless phone batteries could store energy long-term. Cordless phone batteries rapidly lose energy.
