Content Standard: How gases behave based on the motion and relative distances between gas particles. A series of activities was conducted in the Chemistry laboratory of Bloomfield Academy.

The objective of the activity was to observe the behavior of gases under different conditions and to understand the relationships between the pressure, volume, and temperature of gases. The activity began with the students working in groups of eight. Each group was provided with a set of materials, including a syringe, a thermometer, a beaker, an alcohol lamp, a balloon, a tripod, ice, and an igniter. The students were instructed to record the initial volume, pressure, and temperature of the gas in the container. Next, the students were asked to change one of the variables while keeping the other variables constant. For example, they could increase the temperature of the gas by heating it with an alcohol lamp or they could decrease the volume of the gas by using the gas syringe to push the plunger in. They were instructed to record the new values of the variables after each change and even take photos/videos for them to record actual things that happened. As the students made changes to the variables, they observed the behavior of the gas and discussed their observations with their group members. They noticed that increasing the temperature of the gas caused the pressure to increase as well while decreasing the volume of the gas caused the pressure to increase as well. These observations were consistent with the gas laws they had learned in class. After each group had completed the activity, the class reconvened for a discussion of the results. The teacher asked the students to share their observations and discuss the relationships between the variables. The students were able to explain how the gas laws applied to their observations and were able to articulate the mathematical relationships between pressure, volume, and temperature. Overall, the gas laws activity was a success. The students were engaged and actively participated in the activity. They were able to observe the behavior of gases under different conditions and understand the relationships between pressure, volume, and temperature. This activity was an effective way to reinforce the concepts covered in class and help students understand the practical applications of gas laws.
