​ **Problem:What will a ballon do if we change the tempeture?** (Change the temperature of what? The balloon?)  **Research:Hot watehas energy and cool water doesnt** **have energy.** (Science background information on expand and contract)  ** Hypothesis:If I change the temputure of a balloon it will expand or contract. ** (How are you going to change the temperature? THEN...)  **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:** When the balloon had hot air in it ,it expanded and when it had cooler air in it ,it contracted. <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;">
