Objective

Students have now finished taking the last of their GLOBE measurements. In today’s lesson, students will compile and analyze their data. The goal of today’s lesson is for students to explore relationships between ozone and the other factors that they measured. Students will analyze the data from the six GLOBE measurements – ozone, cloud cover, humidity, air temperature, surface temperature, and wind direction. They will do this by using simple calculations and by creating charts, graphs, and pictures to represent their data. These calculations and graphs will allow students to see trends in their data. For example, students may find that temperature is positively correlated to the amount of low-level ozone present (as they discovered is true in Smog City 2 in Lesson 5). However, if the data shows no clear trends or atypical correlations (e.g., ozone highest on cool, cloudy days), students must not be discouraged. Instead, explain possible reasons for anomalous results: 1) five days may be too little data for students to find typical relationships between factors, and 2) factors that cannot be measured at one school (e.g., daily fluctuations in emissions; complex wind flow patterns) also affect the creation of low-level ozone. Students should understand that this is also part of experimental design, and that they would probably be able to come up with more accurate conclusions if they took the GLOBE measurements for a much a longer period of time.

After students have reached their conclusions, they will be able to compare them to their original hypotheses. Students will also be given a chance to compare and communicate their findings with other students.

Students will most likely find the following correlations in their data. However, actual results may vary due to the small number of data points collected and factors beyond the scope of these measurements that affect ozone:

Step-by-step suggested lesson plan

Instructor Activity Student Activity
Tell students that today is the last lesson of the curriculum. Today students will be guided into analyzing their GLOBE data for trends. Tell students they will be able to use the knowledge they have learned in order to see the how the GLOBE measurements they have taken are related. Students listen
Students will analyze their data. Guide students into calculations and graphing related to the data, following the instructions on the worksheets. You may choose to have some of the work, like the calculations of daily average temperature, to be done as a class. Students analyze their measurement data to create graphs and answer journal questions: (p.3-6)
Have students share their graphs and conclusions with the class. Suggestion: Create a poster recapping the students’ final conclusions and what they have learned over the course of the lessons. Students share graphs and findings
As a final discussion for students, ask students to tell each other about something that they learned about that they found interesting. Students complete final reflection journal page: (p. 7)

Expected outcomes

  1. Students will explore how cloud cover, air temperature, and humidity relate to ozone levels on a given day.
  2. Students will build experience graphing data in charts.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
