Expansion+Lab

Expansion and Contraction Lab
 **Problem: What will the effect be when you change the tempature in the water bottle and then put a balloon over the opening of the water bottle.(?)**  **Research:** Expanding=to stretch or get bigger. (contract definition?)  **Hypothesis:If you change the tempature in the water bottle and then put a bolloon over the opening then i think that when you put the bottle in the hot water the bolloon will expand but in the cold water it will go back to normol.**  **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. <span style="font-family: Tahoma; font-size: 14pt; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: Tahoma; msobidifontsize: 12.0pt; msofareastfontfamily: Tahoma; msolist: Ignore;">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; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> <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;">

placed in the cold water. || It layed flat just like it did when it was at room tempature. || <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; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion:**
 * Water Temperature || Prediction || Description of the Balloon ||
 * Room Temperature || Nothing will happen. || It lays flat on the top of the water bottle with no air in it. ||
 * Warm || The balloon will fill with air and expand. || It filled with a little air and stood stright up. ||
 * Cold || The balloon will inflate when the bottle is

First, my hypothisis was correct the balloon expanded i stated that when my group put the water bottle in the hot water the balloon would expand and it did, but i discoverd when we placed the bottle in the cold water after we had it in the hot water it deflated and looked the same as it did when we had the water bottle in room tempature. What did your results show? 70% ||
 * I can state a hypothesis related to the problem and procedure. || I can conduct research about concepts that are related to the topic I am investigating. || I can collect quantitative/qualitative data while conducting an experiment. || I can use the data in my results to draw a conclusion about what happened and why. || Overall, I can apply the scienctific method to solve a problem. || Total ||
