Expansion and Contraction Lab
 **Problem: what will happen to the baloon when you place the bottle in the warm water then in cold ? **


 * Hypothesis: If i put the bottle in the warm the balloon will grow (What will happen when it is placed in cold water?) **

**Research:** expand means to take up more space and contract means to take up less space.

 **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.  **Results:** 
 * Materials: Safety goggles, Balloon,** **Plastic bottle, Warm water,** **Cold water**

My results showed that when i placed it in warm water it did expand then when i put it in cold it did contract (Discuss the description of the balloon that supports it expanded and contracted.)
 * Water Temperature || Prediction || Description of the Balloon ||
 * Room Temperature || X || the balloon is flat and hanging ||
 * Warm || the balloonwill be standing up in the air || the balloon had stood straight
 * Cold || the ballloon will be flat and droopy || the balloon had flanted out ||
