**Problem:what will happen to the balloon when it (the bottle) is placed in cold and hot water**  **Research:Expand:all the atoms vibrate Contract:taking away energy (to take up less space) (expand) **  **Hypothesis:tf you put the balloon over the hot water bottle then the balloon will fill up (What about 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. 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;"> Describe the physical characteristics of the balloon.

It ecpanded because the hot water blew it up. the cold water with the balloon contracted because it was in cold water not hot.**
