 **Problem:What will happen to the balloon if we put it in hot or cold water?**  **Research:Heat rises and cold sinks** (What does this cause matter to do?)  **Hypothesis:If we put the balloon in hot water then the ballon will inflate. If we put the balloon in cold water then the balloon will deflate.**  **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;"> Use adjectives to describe the appearance of the balloon. <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion:** <span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: left;">My hypothesis was correct. I stated that if we put the balloon in hot water then it will inflate. If we put the balloon in cold water then it will deflate. My results were that in the warm water the balloon inflated and in the cold the balloon deflated.
