Heat+1

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:** Which temperature will make the balloon active? (Are you measuring the activity level?)


 * Research:** Expand= to increase in size. Contract= to decreas in size. (What about contract?)


 * Hypothesis:**If i put the water bottle in hot water then it will EXPAD,if i put the water bottle in cold then it will CONTRACT. (contract?)


 * 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. 3.) Place the bottle with the ballon in the warm water for about 30 seconds. 4.) Observe the balloon again and record any changes you see in the balloon. 5.) Remove the bottle and balloon from the warm water and quickly place it in the cold water for about 30 seconds (or until it cools). 6.) Observe the balloon and record any changes you see in the balloon.


 * Results:**

You need to describe the physical characteristics of the balloon. stay deflated || Deflated || Has mass and vloume ||

 * Room Temperature || nothing it was
 * Warm || balloon will blow up || Took up spaces
 * Cold || Deflated || Dflated ||
