Team Leaders are responsible for organizing the final document.  You may send it to me through google docs (my email is [email protected]), but I also need a printed copy for grading.  A copy of the assignment and rubric is attached here for your reference.

As we moved from the PhET simulation on gas behavior, we have begun quantifying gas behavior.  For homework tonight, read and summarize section 13.2 in your textbook on the Gas Laws.

As further reinforcement of gas behavior and properties, watch the Bozeman video (link below) and write a summary, including examples.  He is using the same PhET simulation we used, so it should help you better understand the concepts and relationships between the variables.

 

As an introduction to the behavior of gases (like carbon dioxide) and a follow-up to today's PHET simulation on gas behavior, watch the Khan Academy video (attached below) and summarize the video with examples from the video.

 

 

We will be moving into a study of gas behavior as we continue to look at carbon dioxide as a greenhouse gas.  For homework, read and summarize section 13.3 in your textbook on models to describe gas behavior.

• Also, continue your online research of the section you have chosen for your team global climate change report.

We have been talking about fossil fuel combustion, energy release and carbon dioxide gas production.  This leads to a study of gases.  For homework:

Review your class notes and lab notes as well as chapter 10 in your textbook to complete questions (1-11) of the standardized test practice on page 357 at the end of chapter 10.  You might struggle with #7 , but the others should be manageable.  Even though they are multiple choice questions, you must explain your reasoning for each answer.
