Jason Allen offers a comparative discussion of two important Caribbean poets and playwrights, Aime Cesaire and Derek Walcott, to emphasize the impact of Caribbean literature upon the postcolonial world. By using biographical and historical detail to support his analysis of some of Cesaire and Walcott's key texts, Allen offers insight into what it means to be a Caribbean writer - looking back to a colonial past, and forward to a global future. This audio recording is part the Interviews on Great Writers series presented by Oxford University Podcasts.

Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars.

This research seeks to analyze air cargo hubbing and air cargo operations in Hong Kong International airport and the Leipzig/Halle airport both of which have been awarded numerous times due to their excellent service delivery to their customers and efficient handling of air cargo. The Hong Kong international airport has been rated the busiest airport for worldwide air cargo since 1996. 1n 2013, Hong Kong international airport handled 4.12 million tonnes of freight. The airport covers an area of 1,255 hectares. It has a total of 66 boarding gates with 66 jet bridge gates and seven virtual gates. Leipzig/Halle airport moved more than 887,000 tonnes of cargo in the year 2013. It has been ranked number 2 of all German cargo airports and among the 10 best in Europeans cargo airports. The airport offers a variety of services including airfreight and airmail, warehouse and documentation, perishables, pharma handling and customs clearance among others. Leipzig/Halle airport has presented itself as a reliable air transport and logistics industry. Located at the heart of the German logistics section it has proved itself competitive enough to enter the ever growing markets of East Europe and Asia.

The AirData Web site gives you access to air pollution data for the entire United States. Want to know the highest ozone level measured in your state last year? Ever wonder where air pollution monitoring sites are located? Are there sources of air pollution in your town? You can find out here! AirData produces reports and maps of air pollution data based on criteria that you specify.

This STEM challenge can be used during an air unit. Students are able to find ways to best minimize air resistance. The students are trying to develop a paper airplane that will go the farthest in the class competition.

This STEM challenge can be used during an air unit. Students work together in groups to create a parachute for a lego person. Students are able to find ways to best maximize air resistance. The students need to find the best way to increase the time that the lego person stays in the air when dropped from the second floor to the first floor.

This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.

This is a series of activities demonstrating that air has mass, takes up space, and can exert a force on objects enough to lift them.

By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.

This is a series of investigations about air and its properties. How air exists all around us, and things it is capable of doing.

Phase 1: Definition of Projects and Research Teams (Homework +1 Class)

Each student is assigned the task of proposing a site to investigate within the city and the surrounding region. Students are encouraged to discuss the assignment with community members for suggestions and inspiration. Each student will produce an easel-size poster of their proposal highlighting the following:


Site location;

Reasons for selecting this site;

Potential interest to the community;

Potential logistical problems associated with the proposed site/project.

Posters will be hung in a gallery-walk format, and each student will mark the location of their proposed study site on the classroom map of New York City. The class is given time to read and comment on each of their peers' proposals, after which the instructor will lead a class discussion of the interests, merits, and obstacles associated with each proposal, with the goal of having the class settle on the set of projects on which to move forward.
Students will define groups of 2 to 4 students per project. If more than 4 students are interested in the same site, then multiple groups may develop parallel projects.

Phase 2: Data Collection and Analysis (5 weeks)

In consultation with the instructor, teams develop and implement a sampling protocol, including the documentation of terrain, human activity, and weather conditions (wind speed and direction) at the time of collection. Sample stations and prevailing wind direction are plotted on Google Earth to determine likely sources of particulates. Using binocular microscopes students document size distribution, form, color, and abundance of particulates. This data is analyzed using statistical functions in Excel. Teams use SEM-EDS analysis to determine the composition of particles, and more fully describe their form. Teams submit weekly progress reports, including personal work reports for each team member.

Phase 3: Communication of Results (1 Week)

Teams submit to their instructor a formal laboratory report: Purpose, Equipment, Method, Data Tabulation, Data Analysis, and Conclusions.
Teams prepare an oral presentation, or visual information campaign, targeted at an audience of their choice (e.g., neighbors, church group, community activist group, college administration) using discourse appropriate to that audience. Teams present in an in-class dress-rehearsal prior to their formal presentation. Teams invite members of their desired audience to the presentation (official invitations sent). On the last day of class, the instructor leads a debriefing and critique of the presentations, highlighting results and effective communication techniques.

The image is created from canva app and describes what is air pollution, causes, types, effects and control measures of air pollution.

The Phoenix metropolitan area, like many large cities, has problems with air pollution at certain times of the year. You can do a simple experiment to determine some of the factors that affect air pollution.
