Expansion and Contraction Lab
 **Problem: what will happen to the balloon at room temp.,in cold water, and in warm water?**  **Research:expand means to spread apart and contract means to get closer together**  **Hypothesis: if we put the balloon in warm water, then it will start to blow up (What will happen when you place it in the cold water?) **  **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. <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;">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: 'Arial Black',Gadget,sans-serif; font-size: 110%;"> <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;">

<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! <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion: my hypothisis was correct. I stated that at room temp. nothing would happen, in warm water it would blow up, and in cold water it would deflate, so my hypothisis was correct** You did not use the results to show what hppened that proves you are correct. 55% ||
