Matter+Lab

Goals: I can demonstrate how to effectively follow the scientific method. I can read and follow directions. I can make predictions based on my knowledge of temperature. I can observe and detail qualitative and/or quantitative changes in an object. I can infer what was happening based on my understanding of matter and how the structure of matter reacts under certain conditions. = =  Choose ONE of the labs below to complete. Create a new page called "Matter Labs". Copy and paste it to your wiki. Print a rough copy. Fill in the Problem, reasearch, and hypothesis BEFORE the experiment. You will work in groups of four. Fill in the rest of the sheet. You will video tape the lab process and verbally discuss the answers key questions based on what you observed on the card provided at the station. You will type the information from your rough copy onto the one you pasted in the wiki. The grading rubric can be found below.

Expansion and Contraction Lab
 **Problem: What will happen if you put a water bottle with a balloon on the neck of the bottle in hot water and then in cold water?**  **Research: Mattter:anything that has weight and takes up space. Hot air rises-Cold air sinks Gases move everywhere they can liquid-molecules move more than a solid,but less than gases**  **Hypothesis: If you put the water bottle with the balloon on it in the hot water, then the balloon will expand, and if you put the water bottle with the balloon in the cold water, then the balloon won't expand.**  **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: 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: At room temperature, the balloon didn't blow up at all. When the water bottle with the balloon on it was in the warm water the balloon at the end, blew up a little. In cold water, the part of the balloon that hung down, didn't blow up. The end part of the balloon that went around the neck of the water bottle, the flat part was kind of suctioned down.** <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;">

was going to expand || blew up a little-end- little part expanded on each side of the crease -still has crease || <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: My hypothesis was right. I thought that in the warm water, the balloon was goging to expand, and, and in the cold water, the balloon wasn't going to expand. At room temperature, the balloon didn't expand at all, but in the warm water, the balloon expanded a little. In the cold water, the balloon didn't expand, but where the balloon was over the neck of the water bottle, the balloon was kind of suctioned down. My expiriment proved my hypothesis.**
