Expansion and Contraction Lab
 **Problem:What will happen to the balloon if we put warm & cold water in the boddle (bottle)? ** ...if we put the bottle in warm and cold water.  **Research:** Heat rises & cool sinks (How does this relate to expansion and contrrction?)  **Hypothesis:if we put warm water in the boddle then the balloon wiil strech. What will happen when you place it in cold water? **  **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!
 * Water Temperature || Prediction || Description of the Balloon ||
 * Room Temperature || nothing || nothing ||
 * Warm || inflate || inflate ||
 * Cold || deflate || deflate ||

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion: My hipothisis was correct. We predicted that the balloon would inflate when we placed it in hot water. Then we prediced that in would deflate when we place it in cool water. What did your results show? **
