 **//Problem://What will happen if we add heat/coldness to a balloon?**  **//Research://** Definition:An object taking up more space. Term:Contract Definition:An object taking less space.**  **//Hypothesis://If we add heat or coldness to the balloon then it will increase/decrease size.**  **//Materials:// Safety goggles, Balloon,** **Plastic bottle, Warm water,** **Cold water.** . //**Procedure:**  // 1.) Stretch the opening of the balloon over the neck of the bottle. 2.)  Observe the balloon at room temperature. Record observations. 3.) Place the bottle with the ballon in the warm water for about 30 seconds. 4.) Observe the ballon again and record any changes you see in the balloon. <span style="font-family: Tahoma; font-size: 14pt; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: Tahoma; msobidifontsize: 12.0pt; msofareastfontfamily: Tahoma; msolist: Ignore;">5.) Remove the bottle and ballon from the warm water and quickly place it in the cold water for about 30 seconds (or until it cools). 6.) Observe the ballon and record any changes you see in the ballon. <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Results:** <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;">

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> You need to use adjectives to describe what the balloon looks like (limp, flat. stretched,...)
 * Water Temperature || Prediction || Description of the Balloon ||
 * Room Temperature || The balloon will stay the same. || It is red and uninflated ||
 * Warm || The balloon will inflate. || It is inflated ||
 * Cold || The ballon will shrink. || It went together ||

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**//Conclusion:// The balloon will infalate/deflate if we add heat/coldness (This IS NOT a proper conclusion!!!!!! Go back to your notes/past labs for help.) **
