Gas Laws Guide
This set of activities enables students to investigate what causes pressure, how it is measured, and how it is affected by its own properties and the properties of its container. Students are encouraged to understand how the principles and effects of pressure are generated from specific interactions between many particles.
Since the activities increase in complexity from the first simple models and user interface introductions to the later activities requiring integrated models and sophisticated reasoning skills, we strongly recommend that learners complete the core activities in sequence.
In addition to the activities, there is one survey, a pre-test, a post-test, and embedded assessment pieces that enable the MAC project to evaluate students' progress and draw conclusions about the effectiveness of the activities.
Please make sure to administer the Pre-Test before the core activities and the Post-Test after the core activities. They are an essential part of this research project.
