**Problem:What will happen is you put a balloon on a bottle and put the bottle in hot and cold water?**  **Research:Expand means to take up more space and contract means to take up less space.**  **Hypothesis:If you put a balloon on the top of a bottle and put a bottle in hot and cold water then in hot water it will inflate more than in 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 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;"> Use physical characteristics to describe what the balloon looks like.

(Use the inofrmation in your results to support your conclusion.) **
