**Problem:If (If...is not a question word...try when) you put the bottle with the baloon attached in warm and cold water will the ballon change

?**  **Research:Heat is when molecules are far a part and move rapidly. Cold is when molecules are close together and move very slowly.**

 **Hypothesis:If you place the bottle in warm water then the baloon will expand. If you place the bottle in cold water then baloon will contract.**  **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;">

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> You need to use adjectives to describe what the balloon looks like. You are telling what the balloon is doing.
 * Water Temperature || Prediction || Description of the Balloon ||
 * Room Temperature || I think it will stay the same. || The baloon stayed the same. ||
 * Warm || I think the baloon will expand. || The baloon did expand. ||
 * Cold || I think the baloon will contract. || The baloon did contract. ||

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion:My hypotheis was correct. I stated that if you place the baloon in warm water it will expand. I also stated that in cold water the baloon will contract.** What did your results show?
