matter+labs

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 under "Matter Labs". The grading rubric can be found below.

Expansion and Contraction Lab
 **Problem: what if the ballon dosent blow up** (Is this why you were doing the experiment?)  **Research:** the ballon blow up in the warm but inflated in cold (Expand and contract definitions needed here)  **Hypothesis: the ballon will maybe blow up i n hot and go away in cold (if...then?) **  **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:** <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> No data written in the results table.

**Keeping Ice Frozen**

<span style="display: block; font-family: 'Kristen ITC'; font-size: 14pt; msobidifontsize: 12.0pt; text-align: center;"> <span style="font-family: 'Comic Sans MS',cursive; font-size: 14px;">** Problem **: What material, bubble wrap or tin foil, will keep ice frozen the longest?
 * Research:**


 * Hypothesis:**


 * Materials**: 2 ice cubes, bubble wrap ,t in foil, timer


 * Procedure:**

<span style="font-family: 'Kristen ITC'; mso-bidi-font-family: 'Kristen ITC'; mso-fareast-font-family: 'Kristen ITC'; msobidifontfamily: 'Kristen ITC'; msofareastfontfamily: 'Kristen ITC'; msolist: Ignore;">1.) Using a scale weigh the ice cube. 2.) Wrap an ice cube in tin foil and set on tray. <span style="font-family: 'Kristen ITC'; mso-bidi-font-family: 'Kristen ITC'; mso-fareast-font-family: 'Kristen ITC'; msobidifontfamily: 'Kristen ITC'; msofareastfontfamily: 'Kristen ITC'; msolist: Ignore;">3.) Wrap another ice cube in bubble wrap and set on tray. <span style="font-family: 'Kristen ITC'; mso-bidi-font-family: 'Kristen ITC'; mso-fareast-font-family: 'Kristen ITC'; msobidifontfamily: 'Kristen ITC'; msofareastfontfamily: 'Kristen ITC'; msolist: Ignore;">4.)  Wait 30 minutes. <span style="font-family: 'Kristen ITC'; mso-bidi-font-family: 'Kristen ITC'; mso-fareast-font-family: 'Kristen ITC'; msobidifontfamily: 'Kristen ITC'; msofareastfontfamily: 'Kristen ITC'; msolist: Ignore;">5.) After 30 minutes, unwrap each package. 6.) Weigh the ice cube again. 7.) Write the observations in the chart.
