Expansion and Contraction Lab
 **Problem:What will happen to the balloon when we put the bottle in cold and warm water?**  **Research:** Expand:To take up more space. Contract: To take up less space.  **Hypothesis: If the ballon was in warm waterthen it will blow up. (What about the 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 balloon 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;">


 * Water Temperature ||  || Prediction ||   || Description of the Balloon ||


 * Room Temperature || deflate || flat and wrinkerly ||  ||   ||


 * Warm || the ballon was big || it was cycerler ||  ||   ||


 * Cold || flat and winkerly || it is boncy ||  ||   ||

<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;">**Conclusion: My hypothesis is correct because I said that if you put the bottle in the warm water it will blow up but if you put it in cold water it will deflate and it can bons. (Use your results to support your conclusion.) **
