[Carbon dioxide] and [Particulate] Concentrations of the Air Quality In and Around the Schools of Lumsden.

Objective: To measure the CO2 levels  and particulate matter contained in the air in and around Lumsden elementary and high schools.

Hypothesis:

IF we measure the carbon dioxide levels of the air in the shop, gym, all parking lots, foods lab, multipurpose room, large computer lab, band room, library, chemical storage room, office and one classroom per each side of each wing in the high school.  We will also test the gym, one portable classroom, library, office, science lab, grade 8 room, canteen , kindergarten room and grade 6 room at the elementary school. THEN we will be able to compare the AQHI in each test site and find that Lumsden Schools are on par with the average national carbon dioxide levels laid out in the Clean Air Act.

IF we measure the particulate matter levels of the air in the shop, gym, all parking lots, foods lab, multipurpose room, large computer lab, band room, library, chemical storage room, office and one classroom per each side of each wing in the high school.  We will also test the gym, one portable classroom, library, office, science lab, grade 8 room, canteen , kindergarten room and grade 6 room at the elementary school. THEN we will be able to compare the AQHI in each test site and find that Lumsden Schools are on par with the average national particulate levels laid out in the Clean Air Act.

Data:

Carbon Dioxide and Temperature:

*Due to faulty lab equipment temp from day 3 in all but the gym are unreliable*

Gym  * Air quality at the NE side of stage

Day One: The carbon dioxide level was 1377 ppm which is over the circulation of the air levels, which is 1200 ppm. This means there were a lot of people and odours in the gym.There was the grade 11 class in the gym. The temperature was  21.28℃.

Day Two: The carbon dioxide level for this day was 1264 ppm which is just over 1200 ppm which is air circulation level. There was also a full gym class in there. It was a grade 11 class in the gym again. The temperature was at 21.75℃.

Day Three: The last day we tested for carbon dioxide levels it was at 34.88 ppm which is way under but, there was no class in the gym this day. The temperature was at 21.31℃.

Over all the carbon dioxide levels were higher than what it should be in a room. Except because it is a gym class it makes sense why the the carbon dioxide is so high. Due to body odours and a good amount of people being in the gym at once it pushed the levels up. The temperatures stayed the same thought the days we tested.

Band Room  *Air quality test completed at the middle of the back of the room

Day One: The carbon dioxide level was 1508 ppm which is quite a bit over the air level circulation at 1200 ppm. There was a full class in the band room at this time.The temperature was at 22.11℃.

Day Two: On this day the carbon dioxide was 1017 ppm which is possible but, for the fact there was no people in the room when we tested this day. So it’s not that good because, it’s close to the max number which is 1200 ppm. The level is over normal levels which is not that good but, because there was no people in the room, I say this is poor air quality.The temperature was at 21.78℃.

Day Three: This day the carbon dioxide level was at 103.8 ppm. When we did this test there was no one in the room and the room was also really cold.

Over all the days we tested I noticed that when there are people in the room playing whatever kind of instrument, the carbon dioxide is going higher than what it should be at compared to when no one is in the room. The temperature was about the same for each day.

Multi * Air quality tested at the third table from the left side of the room

Day One: This day there was no one in the room and the carbon dioxide level was at 1424 ppm which is over the 1200 ppm. We would say this isn’t that good considering no one was in the room.The temperature was at 21.89℃.

Day Two: On this day the carbon dioxide level was at 809.2 ppm which is under and there was also no one in the room with us this day too.The temperature was at 22.63℃.

Day Three: This day the carbon dioxide level was at 92.87 ppm which was at it’s lowest throughout the three days we were testing for. Once again there was no one in the room.

With the data we observed the carbon dioxide levels went lower and lower throughout the three days we were testing while there was no one in the room.The temperatures are almost the same for both days we tested and the other day we had faulty lab equipment.   

Office * Air quality tested at the chairs in front of Mrs.Grants desk

Day One: This day the carbon dioxide level was at  2225 ppm which is way over the right amount of carbon dioxide in the room, there was about 4-5 people in the room while we were testing. The temperature was at 22.91℃.

Day Two: For this day the carbon dioxide level was at 1368 ppm which is still over 1200 ppm but, it is way better then the first day we tested. There was also 4-5 people in the office while we tested the levels.The temperature was at 22.61℃.

Day Three: On the final day of testing the carbon dioxide level was at 83.67 ppm which is under but, this is good because it means there was not much carbon dioxide in the office this day. There was still the same amount of people in the office like the other two days we were testing.

The first day that we tested for carbon dioxide level it was really high and throughout the other two days we test the office the level of carbon dioxide went down quite a bit. For the two days that we have the temperatures for they were about the same.

Average temperatures and Graphs for these rooms.

*Due to faulty lab equipment temp from day 2 and CO2 from day 1 are unreliable*

Library

On day 1 the average  CO2 was 2465*ppm and that is a high level considering there was ten people in the room. We found that this data is unreliable for our CO2 sensor was faulty. The average Temperature for this day was 22.99℃.

Day 2 the mean carbon dioxide read 414.8 ppm and there was about 20 people with computers and printers running in the room. This is adequate CO2 for this room.

On day 3 the average CO2 read as 767.4ppm. With a temperature of  23.15℃ there was about 30 people the room. This CO2 is quite acceptable for the room.

This room has a good CO2 with adequate air ventilation.

Library graphs can be found here

Shop

On day 1 the average Co2 was 2037*ppm and this is a really high level but this data is not relied on. The temperature for this room was  22.88℃.

Day 2 in the shop the CO2 read as 416.2 ppm which is a good level with about 15 people in the room.

On day 3 the Co2 in the shop was 658.1 ppm and the Temp was 23.80 and this is adequate for the room.

We found that the shop had fairly acceptable air quality.

Shop graphs can be found here

Chem lab

Day 1 in the chem storage lab the CO2 was 2007*ppm and this is unreliable data. The temperature for this room was 23.51. There was only 2 people in the room.

On day 2 the average CO2 read as 685.1ppm and this is slightly high considering that there was only 4 people in the room but it is still healthy and acceptable.

Durning day 3 the CO2 was 450.5 ppm and the temperature was 22.96. There was 2 people in the room.

The chemical storage lab had acceptable air quality and good air flow.

Chemical lab graphs can be found here

Senior Math

On day 1 the CO2 in The senior math room read as 1695 ppm and this was found as unreliable. There was about 20 people in the room with no noticeable odour. The temperature was 23.48

Day 2 the CO2 was 611.4 ppm and this is fairly acceptable. There was about 20 people in the room.

We found that on day 3 the CO2 was 779.3ppm and there was about 25 people in the room. The temperature was 23.09.

The senior math room has good CO2 levels and air flow.

Senior Math room graphs can be found here

Computer lab

Our CO2 sensor found an average of 2183*ppm on day 1 but due to a faulty sensor this data is insufficient. The average temperature was 23.32 degrees Celsius.

Day 2 the CO2 was 539.6 ppm. There was about 7 people in the room. This is a good level of carbon dioxide.

On Day 3 the CO2 was 938.6ppm and this is fairly high considering there was 2 people in the room but it is still healthy and safe. The temperature was 23.27

The computer lab had acceptable air quality.

Computer lab graphs can be found here

Food Lab

Day 1

Both the CO2 and the temperature sensor were both below average for the Carbon Dioxide ratings. However, due to the washing machine going and the person in the room on her computer, the Carbon Dioxide readings was rising while the temperature was falling.

Day 2

The Carbon Dioxide Levels stayed around the same area as it was on Day 1. Around the 350 ppm. This is okay for this area. The Temperature also stayed around 20-21°C.

Day 3

The last day, We had a faulty Carbon Dioxide tester. It raised from about 350 ppm from the first two days to around 1780 ppm. Nothing changed in the room, still the teacher on her computer. However, it could have also had to do with it being the coldest day out of the three days.

Graphs for the above room can be found here.

Senior ELA Room

Day 1

On Day 1, due to the room being full of sweaty teenagers, the temperature quickly jumped  from 1100 ppm to 1300 ppm. The Temperature sensor also saw a hike as we entered the room. It jumped from under 20 degrees to 22 degrees in less than 30 seconds.

Day 2

This Day, there was less people in the room than on the first and third days. The Carbon Dioxide Level dropped by over 800 ppm to sit around 215 ppm. While, once again, the Temperature sensor made it’s steep incline to the high 20’s

Day 3

This day, the classroom was full again, so the temperature sensor reached levels of 2300 ppm. I also noticed during this time that somebody opened a fresh bottle of water that was store bought which spiked our Carbon Dioxide levels greatly. The Temperature sensor once again took it’s steep incline to around 22 degrees celsius

Graphs for the above room can be found here

Winter Room

Day 1

On Day 1, There was nobody in the classroom, However, due to being the first classroom we tested after the parking lots, We had a major spike (820 ppm)  in Carbon Dioxide. The Temperature Sensor on the other hand, raised to 20 degrees celsius.

Day 2

On Day 2, The Carbon Dioxide Sensor stayed at 305 ppm. Once again, there was no people in the room. However, the temperature sensor raised to 20 degrees celsius.There was a slight fall from the previous day.

Day 3

On Day 3, The classroom was finally full. We got our first take of the full classroom and got a reading of 2100 ppm. This is expected as there are many teenagers in one room at once. The Temperature sensor once again, raised up to 20°C.

Graphs for the above room can be found here

Parking Lot 1

Day 1

On the first day in the parking lot, we had major spikes between 300 ppm-320 ppm. This isn’t as high as we expected considering it is a parking lot full of vehicles. The Temperature was rising to about 16 degrees celsius.

Day 2

On the second day, There was a drop of about 100 ppm to 211.5 ppm. This is due to less vehicles in the parking lot and also a more cloudier day than the previous exam date. The Temperature fell considerably compared to the last entry. It fell to 13 degrees celcius.

Day 3

On the Final Day, the clouds finally opened up and revealed more Carbon Dioxide. The only exception was the parking lots. The parking lots were decreasing fast. In this parking lot, it fell to 1100 ppm. The Temperature fell to the 10 degree mark.

Graphs for the above room can be found here

Parking Lot 2

Day 1

On the first day, the Carbon Dioxide levels fell between 290 and 320 ppm. Which is once again quite low for being outside. The Temperature sensor however was raising to about 15 degrees celsius which too, was not too large.

Day 2

On the Second Day, The Carbon Dioxide levels fell to 300 ppm. This reading is still in average with day 1 and is on par with the national average. The Temperature sensor on the other hand fell to about 7 degrees celsius

Day 3

On the final day, The Carbon Dioxide levels once again raised to 1280 ppm because of the clouds opening up and more Carbon Dioxide presenting itself. The Temperature sensor fell to 5 degrees celsius.

Library / Foods lab / large computer lab:

Average:

Computer Lab: temp- 23.4 lux- 345

Food Lab: temp- 22.4 lux- 540

Library: temp- 23 lux- 343

The temperatures and lumens of these rooms stayed relatively similar over the three days with a small amount of fluctuation. This is influenced by a few factors such as our testing location each day and external factors like people being in the room and producing body heat and the lights flickering due to voltage changes. The Computer Lab would have been affected by the blinds and computers being run. The Library would have been affected by people being in the room and using computers and phones. The Food Lab would have been affected by the washing machines being run and previous classes cooking food. The temperatures of these rooms were similar however the Food Lab had more light particles due to being a bright room.

The graphs for the above rooms can be found here.

Illumination data is unreliable on Day 1

Band room

day 1:

  • Average Temperature- 22.12
  • Average Illumination- 791.5
  • Highest Temperature was day 1 because there was a class going on and there was a large amount of people causing the room to get warmer from body temperature
  • Illumination data is unreliable because it was not picking up the data properly on day 1

day 2:

  • Average Temperature- 21.99
  • Average Illumination- 269.2
  • Temperature was in between day 1 and day 2. There was a class in the room the period before but not when we entered the room. The school temperature was warmer and giving off heat on day 2
  • Illumination was rising and dropping because the lights were getting dimmer at times and brighter

day 3:

  • Average Temperature- 20.03
  • Average Illumination- 208.2
  • Lowest Temperature was day 3 because there was no class going on that period or the period before. Room was empty and there was no body heat and the school temperature overall was colder that day.
  • Illumination was the lowest because the lights are fluorescents and when we first went in, we had to turn on the lights as, no one was using the room, and they took some time to get brighter.

Senior ELA 

day 1:

  • Average Temperature- 21.17
  • Average Illumination- 791.5
  • Illumination data was unreliable because it was not picking up the data properly on day 1
  • Temperature was because the weather was warmer that day and the sunlight was coming in through the windows

 day 2:

  • Average Temperature- 20.01
  • Average Illumination-191.0
  • Lowest temperature was day 2 because it was cloudy and colder, Krawetz room is at right side end of the school which means the weather would affect the heat of the classroom.
  • Lowest illumination because the blinds were shut which made the room less brighter than it was on day 3.

day 3:

  • Average Temperature-21.73
  • Average Illumination-361.0
  • Highest temperature was day 3 because it was a nicer day out than day 1 and day 2. The heat from the weather could have entered through the windows. There were more people in the room on day 3 because a couple people were missing the other days and the body heat was more greater on day 3.

Winters room

day 1:

  • Average Temperature- 17.97
  • Average Illumination- 791.5
  • The temperature was adjusted more on day 1, causing it to be warmer than day 2, there was a no class going on so there was a low amount of body temperature and the weather was warmer that day
  • Illumination Data is unreliable because it was not picking the data properly on day 1

 day 2:

  • Average Temperature-16.29
  • Average Illumination- 296.2
  • Day 2 was the lowest temperature because Winter’s room is at the end of the school and when the doors open they get the excess wind/breezes that come into the hallway. It was cloudy and cold out.
  • Day 2 was the lowest Illumination because there was no class going on so the lights were off and when we turned them on, they needed time to get brighter

 day 3:

  • Average Temperature-20.90
  • Average Illumination- 350.5
  • Highest temperature was day 3 because there was a class going on and the room was crowded with people causing higher body temperature in the room and the school furnace heat was going off into her room
  • Illumination was the highest because there was a class already in there and the lights were already on, so it needed no time to brighten up

Graphs for the above rooms can be found here

Senior Math 

Day 1: temp- 21.18

Lux-773.0

Day 2: temp- 22.43

Lux- 363.9

Day 3: temp- 20.43

Lux- 535.8

The temp in the senior math room is cooler because her room is at the end of the school’s wing, right by the doors to go outside also her room has 2 outside walls. If the outside air is cooler it would make the room to be cooler, which would have an impact on the temperature from the doors opening and letting the air. On day 2 the weather was warmer so the classroom was warmer.  On day 1 the Lux was higher because it was sunnier outside. Her room does not have a lot of students at this time  each day so their body temperature will not increase the room temperature a lot.

Shop 

Day 1: temp- 20.59

Lux- 2414

Day 2: temp- 23.03

lux-1517

Day 3: temp- 22.34

In the shop room where the students weld it has more fumes, so it will increase the illuminations levels and will be very high. On day 2 the levels of illuminations levels are higher because at that time the students were working with the equipment. The air temperatures in the welding room are around the same because of the students body temp increases it. There are not any windows in the classroom or the shops building area so it does not increase the illuminations levels.

Student parking lot

Day 1: temp-15.11

Lux- 5969

Day 2: temp- 10.16

Lux- 8460

Day 3: Temp- 2.04

Lux- 3387

In  the student parking it is filled with a lot of cars so the levels of illumination are very high from all the fumes the cars produce. If there aren’t a lot of cars in the parking lot the illuminations levels won’t be as high.  On day 2 the levels of illumination were the highest because there were more vehicles that arrived in the parking lot from the morning, so the levels were high. On day 3 the temperature of the air was much colder than day 1 and 2. Which caused the levels of illumination to drop.

Lumsden Elementary School:

Carbon Dioxide and Temperature Levels

Carbon Dioxide Levels

Carbon Dioxide is a colorless and odorless gas vital for life on earth. Carbon dioxide is measured in ppm (parts per million.) Temperature is measured in degrees celsius.

*Due to faulty Lab Equipment, some data with the CO2 sensor will be unreliable*  

Elementary School Gym

On day 1 the carbon dioxide level was 1105 ppm. This is sufficient air circulation. In the gym this day there was a class with about 24 kids and 27 including us. The temperature this day was 20.93 degrees celsius.

On day 2 the carbon dioxide level was 967.3 ppm. This is sufficient air circulation. We still would have thought the CO2 level would be higher because the gym was full of kids. In the gym this day there was about 20 kids and 23 including us. The temperature this day was 21.20 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature this day was 23.82 degrees celsius.

In conclusion the air circulation in the Elementary school gym is adequate.

Portable Classroom

On day 1 the carbon dioxide level was 1274 ppm. This is a little over the acceptable air quality act but is still adequate.  This can cause odor problems. In the portable there was only the 3 of us.  The temperature in the portable was 81.45 degrees celsius. We found it warm in there that day.

On day 2 the carbon dioxide level was 1202, once again this a little over the limit but that is nothing major. In the portable there was 4 of us this time. The temperature in the portable was 25.60 degrees celsius,  it was very cold outside that day, and we found that the portable was colder than the first day.

On day 3 the carbon dioxide sensor was unreliable. The temperature this day was 22.82, once again we found the portable colder.

In conclusion in the portables the air circulation is acceptable but doesn’t always have sufficient air quality.

Library  

On day 1 the carbon dioxide level was 982.8 ppm. This is sufficient air circulation. This day there was only 4 of us in the library. The temperature this day was 89.32 degrees celsius.

On day 2 the carbon dioxide level was 1260 ppm. This is a little over the limit, but this day there was also about 16 kids in there 19 including us. The temperature this day 22.74 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable this day. The temperature this day was 23.66 degrees celsius.

In conclusion the library’s air circulation is adequate.

Office

On day 1 the carbon dioxide level in the office was 930.6 ppm. This is sufficient air circulation. In the office this day there was 5 of us. The temperature in the office this day was 136.3 degrees celsius.

On day 2 the carbon dioxide level in the office was 986.7 ppm. This is sufficient air circulation. In the office there was 6 of us. The temperature in the office this day was 22.72 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature in the office was 22.14 degrees celsius.

In conclusion in the office the air circulation is very adequate.

 

Science Lab

On day 1 the carbon dioxide level in the science lab was 1423 ppm. This is over the acceptable air quality act. On this day there was a full class. The temperature on this day was 109.4 degrees celsius.

On day 2 the carbon dioxide level in the science lab was 1628 ppm. This is over the acceptable air quality act. There was a full class in the science lab this day. The temperature on this day was 22.05 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature in the science was 21.46 degrees celsius.

In conclusion the air quality in the science lab is not adequate and needs improvement.

 

Grade 8 Classroom

On day 1 the carbon dioxide level in the grade 8 classroom was 1409 ppm. This is over the acceptable air quality act. A thing that is important to note is that the windows in this classroom do not open. There was only 3 of us in the classroom. The temperature this day was 56.65 degrees celsius.

On day 2 the carbon dioxide level in the grade 8 classroom was 1127 ppm. This is sufficient air circulation . There was only 3 of us in the classroom this day. The temperature in the classroom was 22.14 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature was 22.85 degrees celsius.

In conclusion the air circulation in the grade 8 classroom for the most part is acceptable, but could improve.

Grade 6 Classroom

On day 1 the carbon dioxide level in the grade 6 classroom was 1548 ppm. This over the acceptable air quality act. There was only the 3 of us in the classroom. The temperature in the classroom was 37.23 degrees celsius.

On day 2 the carbon dioxide level in the grade 6 classroom was 1515 ppm. This is over the acceptable air quality act. There was only 3 of us in the classroom this day. The temperature was 21.96 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature was 22.40 degrees celsius.

In conclusion the air circulation in the grade 6 classroom needs improvement, it could be a lot better.

Kindergarden Room

On day 1 the carbon dioxide level in the kindergarden was 1237 ppm. This is a bit over the acceptable air quality act. There was a full class in there. The temperature in the classroom was 136.7 degrees celsius.

On day 2 the carbon dioxide level in the kindergarden room was 1278 ppm. This is a bit over the acceptable air quality act. There was only the 3 of us in the classroom. The temperature in the classroom was 23.4 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature was 23.35 degrees celsius.

In conclusion the air quality in kindergarden room for the most part is acceptable but could be better.

Canteen

On day 1 the carbon dioxide level in the canteen was 1062 ppm. This is sufficient air quality. There was 5 of us in the canteen. The temperature in the canteen was 123,8 degrees celsius.

On day 2 the carbon dioxide level in the canteen was 1057 ppm. This is sufficient air quality. There was 4 of us in the canteen. The temperature in the canteen was 22.81 degrees celsius.

On day 3 the carbon dioxide sensor was unreliable. The temperature in the canteen this day was 27.33 degrees celsius.

In conclusion the air circulation in the canteen is adequate.

The graphs for the above rooms can be found here.

Conclusion:

In conclusion we tested the carbon dioxide levels in the the shop, gym, all parking lots, foods lab, multipurpose room, large computer lab, band room, library, chemical storage room, office and each classroom on each wing of the school in the high school. The elementary school we tested the gym, one portable classroom, library, office, science lab, grade 8 room, canteen, kindergarten room and grade 6 room. With all of this data we collected we learnt that the high schools air quality is adequate, but it can quickly jump from acceptable air quality to very poor air quality depending on the number of people in the room at the certain time. It is very dependant on what is happening in the classroom and how many people are in the classroom at the time. With all of our data from the elementary school we have learnt that the air quality is acceptable in about half of the classrooms but the other half needs improvement. Some classrooms had very good air quality but some air quality was very poor. Our hypothesis is both rejected and accepted based on our data. We believe that the high schools air quality is accepted, but the elementary school is not. The elementary schools air quality is about half and half, half of the schools is okay and the other half is not. In the end we discovered that between the two Lumsden schools the air quality is acceptable and there are no concerns.
