Ideal Gas Law 

A hypothesis on the experiment of filling a can with steam and then placing it in a cool water bath upside down so that the opening is completely submerged.

The conclusion to the experiment: when the opening of the can was free of the water bath, the change in phase of the steam to water caused the can to implode.

An experiment using a manometer to determine the density of water.

The conclusion: by measuring the height that the water ascends to in the manometer and calculating the volume of the column 

A bell jar is sealed and the pressure is decreased inside, what will happen to the marshmallows?

The predictions of the group about what would happen during and after the experiment.
Conclusion: The marshmallows did expand but when the bell jar was purged and the pressure returned to room pressure the marshmallows shrank and became small and wrinkly.

An experiment in which a tube is ran through a pressure sensor and on the other end of the tube is a syringe. As the plunger is depressed and the volume inside the syringe decreases the sensor monitors the change in the pressure inside the tube.

Pressure (kPa) vs Volume (mL)

This experiment shows the relationship between temperature and volume by placing a stopper and a tube over the opening in a flask and attaching the other end of the tube to a syringe. When the temperature inside the flask changes, the volume inside the syringe will adjust as well.

Temperature (C) vs. Volume (cc)

The relationship between Temperature and Volume is linear (Y=X)

This experiment shows the relationship between temperature and pressure. The same vial is used that has a stopper and a tube in it, this time the tube is connected to a pressure sensor and as the vial heats up the pressure sensor adjusts accordingly.
