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

Expansion and Contraction Lab
 **Problem:Will the balloon expand or contract when it is put in hot or cold water ? **  **Research: The balloon expanded when it was put in the hot water(definitions for expanding and contracting) **  **Hypothesis: if we put the bottle in the warm water then the balloon atached to the botle will expand (What will happen when you place it in cold water?) **  **Materials: Safety goggles, Balloon,** **Plastic bottle, Warm water,** **Cold water**  **Procedure:put the bottle in both the hot and the cold water**  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;">

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; mso-bidi-font-size: 12.0pt; msobidifontsize: 12.0ptmsoBidiFontSize;"> Use adjectives to describe what the balloon looks like. You are telling what the balloon is doing. <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 12pt; msobidifontsize: 12.0ptmsoBidiFontSize;">**Conclusion:My hypothesis was correct. I stated that the balloon would expand when it was put in the warm water.When it was put in the cold water it deflated whaen i was put in the warm it expanded. What did your results show? My experiment proved my hypothesis.**
 * Water Temperature || Prediction || Description of the Balloon ||
 * Room Temperature || stay normal || it stayed the same as it was when we put the balloon on the bottle ||
 * Warm || expand || the balloon got bigger in size ||
 * Cold || contract || it basicly deflated ||
