# Ch 2: Physical Science - Understanding Gases: Help and Review

The Understanding Gases chapter of this High School Physical Science Help and Review course is the simplest way to master gases. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of gases.

## Who's it for?

Anyone who needs help learning or mastering high school physical science material will benefit from taking this course. There is no faster or easier way to learn high school physical science. Among those who would benefit are:

• Students who have fallen behind in understanding relevant scientific laws or the properties and characteristics of gases
• Students who struggle with learning disabilities or learning differences, including autism and ADHD
• Students who prefer multiple ways of learning science (visual or auditory)
• Students who have missed class time and need to catch up
• Students who need an efficient way to learn about gases
• Students who struggle to understand their teachers
• Students who attend schools without extra science learning resources
