Step 1: Gather materials and necessary information. a) You will be provided with these initial materials:  2 plastic resealable bags  3–5 “000” size empty gelatin capsules  One 10 mL graduated cylinder to measure purified or distilled water  5 mL distilled water  1 g calcium chloride  1 Fahrenheit or Celsius thermometer  1 funnel  Clock or stopwatch b) Make sure you use the materials given only for reference purposes in Steps 1 and 2 to help you with ideas in the design phase. Building the device does not occur at this point and any materials you alter or destroy will not be replaced. c) Be sure to organize your materials and make sure that the chemicals are handled safely. d) Do not allow substances to mix until the testing phase begins. e) Be sure you have paper and a pen or pencil to record data before, during, and after the testing phase of the project. This data will be reported in your final report. f) The reaction that will be used is the dissolving of calcium chloride in distilled or purified water. The action of dissolving calcium chloride is an exothermic process that can be detected by an increase in temperature. g) Remember to treat tools and materials with care and respect, and to use all safety precautions that you would in a laboratory exercise. Step 2: Design the device. a) Begin by writing a description and/or drawing a diagram of the expected design of your device, using these requirements:  Your device must allow temperature data to be collected both before and after the device is activated.  Your device must release energy to the environment and it must be a controlled reaction. This means that you must have a way to start the reaction at a set time. Your device must maintain the room temperature for 15 seconds or more, then be activated by you to increase
