The groups of three spiders in their enclosures will then be put in their respective temperature environments. 3 enclosures containing spiders will be placed inside in a room temperature environment. These spiders will be in a styrofoam box kept at 20°C for the duration of the project. 3 other enclosures will be placed in the cooler environment. A layer of ice below the enclosures will maintain a cold temperature for the styrofoam box used for the cool condition. A thin, flat layer of cardboard will separate the enclosures from the ice below them. A hole in this layer of cardboard will serve as a place to periodically add more ice to maintain a constant temperature. The previous ice will melt and drain out the bottom via a small hole. The last 3 enclosures will be heated by a heat lamp at roughly 25°C. Each enclosure housing for the three conditions will be comprised of the same styrofoam box for insulation purposes and fixed with a thermometer to ensure a consistent temperature of the course of the five days. All 9 spiders will be allowed to make webs during this period of time. The spiders will be given food/water and the ice will be switched as needed. After 5 days, each plastic cup will be weighed.
