Expansion and Contraction Lab
 **Problem:What will happen if I expand and contrast water?** (Is this what you had to do in the experiment? What about the balloon?)  **Research:expands means to make something bigger while contrast means to make smaller.**  **Hypothesis:If i expand and contrast water then it will take up less or more space.** (In that order? expand=less space/contract=more space?)  **Materials: Safety goggles, Balloon,** **Plastic bottle, Warm water,** **Cold water**  **Procedure:** to stretch the balloon over the empty bottle  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;">

Use adjectices to describe the balloon! <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion: my hypotheses was correct, I stated that the balloon would flow partially up in room temperature. In warm water the balloon went straight up and in cold water the balloon went on its side. So my hypotheses was correct I had learned that expand means to make something become larger and contrast means to make something smaller.** I will do better by looking back at all of my notes and listen to you as all of the time to see if I can do better and maybe stay after once and a while to do better for more than just the blog I mean in the whole time I will be here.
