Introduction

Plan We are investigating how surface area to volume ratio affects the rate of heat loss. Aim The aim of this investigation is to answer the following questions: Why do elephants have trouble cooling down? And why do mice have trouble keeping warm. Apparatus 5x cans (5 different sizes) 1x Bunsen burner 1x heatproof mat 1x Thermometer 1x Ruler 1x Kettle 1x Stopwatch 1x Tripod 1x Gauze 1x Clamp and stand Plan * Label each can from A to E in ascending order, A the biggest and E the smallest. A representing the mouse and E representing the elephant. ...read more.

Middle

* With a stopwatch ready to start timing, switch off the gas to turn off the Bunsen burner and start timing. * Read and record the temperature on the thermometer every two minutes for twenty minutes. * Repeat this for all of the other cans, twice for each one and make a recording of all the temperatures, and work out the averages. Safety * Always wear safety glasses during the practical to protect the eyes and avoid any hot water being splashed into them. * Make sure any long hair is tied back and all ties or pieces of loose clothing are secured to avoid them getting in the way or catching a light. ...read more.

Conclusion

Factors I cannot control but most consider There will be some factors in this experiment that may affect my results, which I cannot control, but must take into consideration, such as : * The room temperature - the room temperature will go up and down due to Bunsen burners being switched on and off, and the opening/closing of windows/doors etc. * The humidity of the room- cannot be controlled but could affect the results. Prediction I predict that the can representing the mouse (Can E) will cool the quickest as it will have less water inside it so it will cool down faster, as the smaller volume means heat will have a shorter distance to travel to escape. ...read more.
