Almost all Anatomy and Physiology course require the student have a basic level of chemistry knowledge. Lesson 02 Chemistry covers the basics of inorganic chemistry, organic chemistry, physics, and nutrition that most A&P student need to make it through the course.
Keep in mind that each of these topics takes about a year of college to gain a better understanding; this video series is just a quick survey to get you up to speed.

The GLOBE Cave Protocol Field Guide utilizes existing GLOBE protocols to explore an extreme environment. Caves provide an opportunity to utilize GLOBE protocols to investigate underground environments and compare them to surface environments. Outside the cave, students record elevation, MUC, latitude and longitude, air temperature, relative humidity and air pressure. Inside the cave, students record air temperature, relative humidity and air pressure as well as observe and describe cave features in each room. Students also note evidence of biological activity and human impact. If water is present inside the cave, students record water temperature and pH. Follow up questions are included in the Field Guide.

In this activity, students study gas laws at a molecular level. They vary the volume of a container at constant temperature to see how pressure changes (Boyle's Law), change the temperature of a container at constant pressure to see how the volume changes with temperature (Charles’s Law), and experiment with heating a gas in a closed container to discover how pressure changes with temperature (Gay Lussac's Law). They also discover the relationship between the number of gas molecules and gas volume (Avogadro's Law). Finally, students use their knowledge of gas laws to model a heated soda can collapsing as it is plunged into ice water.
