Scientic inquiry moves forward when ideas can be tested. Your rst step is to develop a hypothesis. A hypothesis is a possible answer to a scientic question or an explanation for a set of observations. Your hypothesis is not a fact. It must be tested. Your observations may support your hypothesis or they may not. If they do not support your hypothesis, you have not wasted your time. You have learned that your hypothesis is not correct and have that you must explore further. Write a hypothesis about the volume of a balloon when the temperature of the gas in a balloon has changed in Question 1. Questions 1. Write a hypothesis about the volume of a balloon and the temperature of the gas in the balloon. Scientists test hypotheses by designing controlled experiments. A controlled experiment is one in which all of the variables remain the same except one. The variable that you change in your experiment is the controlled parameter. The variable that is changed because of what you do is the responding variable (or dependent variable). How would you design a controlled experiment to test your hypothesis? 2. Describe your experimental setup. What is the controlled parameter in your experiment? What is the responding variable in your experiment? Procedure Section 2 If at any point you need to exit the lab and come back at another time, click the Save Lab button in the lab, That will save your progress. Then when you re-enter the lab, open the Presets menu and click on My Saved Labs. You can click the latest link there to start at the point where you left off.

To start this activity, click this link for Introduction to Scientic Inquiry 3. The lab will load in a new tab. Click back to this tab to read further instructions and complete the questions below. You can follow along with the instructions below in the Procedures tab in the lab. 2. Note that the balloon in the chamber is lled with a gas at a temperature of 100T. a pressure of 101.3 kPa, and a volume of 153] cm3. . Observe the initial volume and temperature of the gas and record them in the data table. Now, click the arrow above the 1 in the T control area in Live Data so that the temperature is now 200T. Record the new volume and temperature in the data table. Repeat this step again but increase to 300C. Again. record your data. Continue to increase the temperature by 100C each time and record your data until you reach 700C. 9: Temperature (\"(3) Volume (ch) Questions 3. The data collected in the data table is the quantitative data. Qualitative data would be your written observations about what happened in the experiment. Write a short summary of what you observed. 4. You can plot the information in the data table on a graph (use an external tool such as Excel or Desmos to make your graph). Plot the controlled parameter on the horizontal axis and the responding variable on the vertical axis. Attach a copy of your graph here. Choose File no tile selected 5. What variable is plotted on the horizontal axis (x-axis)? 6. What variable is plotted on the vertical (y-axis)? 7. At 450C, what is the approximate volume? 61113 B. What will be the approximate volume when the temperature is 1000\"C? ij 9. After scientists interpret their data, they draw conclusions about their hypothesis. A conclusion states whether or not the data support the hypothesis. Review your hypothesis and look at the information in the data table and the graph. W'hat conclusion can you make about your hypothesis? 10. Assume you are a television reporter and were assigned to do a story about the experiment that you just completed. Write a short summary that you could use as a reporter to tell about the process you learned in this experiment. Use the procedure and results of this experiment as an example
