**Problem: What will happen if you put a water bottle with a ballon on the neck of the bottle in hot water then in cold water?**  **Research:** Matter: any thing that has weight and takes up space. Hot air rises, cold air sinks. Liquid moves more than a solid.

 **Hypothesis: If you put the warm water bottle with the ballon on top of it ballon will expand and if you put the water bottle with the ballon in the cold water than the ballon will expand.**  **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. 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; msobidifontsize: 12.0ptmsoBidiFontSize;">**Results:** <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> You need to describe the physical characteristics. <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: Our hypothesis was correct. I stated that the balloon would expand when it was in the hot water and the balloon in the cold water would contract.My results were... the balloon in the hot water would expand and the balloon in the cold water would contract.**
