**Problem: What will happen if you put a balloon on the neck of a bottle in ow water and in cold water?**  

 
 * Research:** **Matter:anything that has weight and takes up space.** **Hot air rises cold air sinks. Liquids molecules move faster than solids less than gas.**

 
 * Hypothesis: IF you put a water bottle with a balloon on it in a bowl of hot water and cold water, then the balloon will expand when it goes in the hot water and it will contract when it gets put in the 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;">

I stated that The balloon would expand when it was put into the hot water and the balloon would contract when it was put in the cold water. My results showed that when i put the water bottle with the balloon on it in the hot water the balloon would expand and it did exactly that, also i stated that when i put the water bottle with the balloon on it in the cold water it would contract and did that. Therefor my results and my hypothesis were correct.**
