Expansion and Contraction Lab
 **Problem:**  Whats will happen if you put a ballon on top of a empty water bottle in cold and worm watter(?) **Research:**  Expand: take up more space Contract: take up less space ​ **Hypothesis:** (then)it will blow up and then if we put it in the cold water (then)it will deflate
 * If we put a balloon on a empty water bottle and put it in worm water

Materials: Safety goggles, Balloon,** **Plastic bottle, Warm water,** **Cold water**

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. 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.  **Results:** 
 * Procedure:**

deflated || no air || CONCLUTION: As you can see, if you put a balloon on a water bottle in (restate the hypothesis) worm watter then the balloon will blow up. Then if you swich it over to cold water then balloon will deflate. 9Use the wods in your results to support your conclusion) My hypothesis was correct! use physical characteristics to describe what the balloon looks like || 1 **2** 3 4 || 1 **2** 3 4 || 13/20 65% ||

 * Cold || ballon will stay
 * I can state a hypothesis related to the problem and procedure. || I can conduct research about concepts that are related to the topic I am investigating. || I can collect quantitative/qualitative data while conducting an experiment. || I can use the data in my results to draw a conclusion about what happened and why. || Overall, I can apply the scienctific method to solve a problem. || Total ||
