Description | ||
| How do batteries in exploratory equipment fair in extreme temperature conditions in outer space, or at the North Pole? This science fair project was conducted to study how extreme temperatures affect the performance of batteries. The experiment was done using Duracell, Energizer and Eveready AA-size batteries. | ||

| 1. For this science fair project, the independent variables are the type of the battery and the temperature conditions. The dependent variable is the time taken for the battery to run out of power while turning the fan motor. This is determined by keeping time with the clock. The constants (control variables) are the power of the fan motor, the size of the batteries and room humidity. 2. The performance of the batteries will be tested at the following temperatures: -78°C using dry ice, 0°C using ice cubes and 24°C at room temperature. 3. For the 1st test, an ..... | ||
