Question: Are teachers in classrooms on the 1st floor more susceptible to radon exposure than students on the 4th floor?

Hypothesis: If we test for radon on each floor of the building, the 1st floor will have the greatest concentration of radon gas.

Variables:

Independent- floor of school

Dependent- amount of radon (pCi/L)

Constant- data collection time, location of sensor (on the floor),

Procedure:

1. Gather all materials needed for the testing.

2. Identify specific locations on each floor of the building to place the radon testing kits.

3. Place one radon testing kit at each selected location on all floors. Record the exact location of each kit for future reference.

4. Activate the radon testing kits and set a timer for the recommended testing duration (usually 48 hours).

5. After the testing period is complete, carefully collect each radon testing kit.

6. Record the radon concentration levels for each floor in a data table.

7. Compare the radon concentration levels between the floors.

8. Calculate the average concentration of radon for the 1st floor and compare it to the other floors.

Hypothesis: If more Cleaning products or other products that contain vocs are used then the air quality will be worse.

Procedure:

1) Go to one of the areas you want to test the air quality in (bathroom, woods, autos, lunchroom, and the chemistry room)

2) Turn on the air quality tester

Record the air quality levels of the area and put it into a table

3)Repeat all of these steps for all of the areas you want to test

4)Go to a room (english room, history room, math room) that doesn't use many voc´s and record the air quality to use as a control

5)Once you've gathered all your information make a table to display all the information

5)Find the R value to see the difference in air quality

6)Write your analysis and compare to your hypothesis

Hypothesis: If we test the levels of carbon dioxide in the culinary rooms and then a regular classroom then the indoor air quality of the culinary rooms will be worse because of the release of carbon dioxide from their stoves.

Variables:

Independent - Location

Dependent - Carbon Dioxide

Constants - Time (120 Seconds)

Procedure:

1. Go to the culinary room, calibrate the air quality detector and place it down, preferably close to the stoves and wait 120 seconds

2. Record the CO2 data from the culinary room in our lab notebook

3. Go to a regular classroom and repeat the same testing process

4. Record the CO2 data from the regular classroom in our lab notebook

5. Analyze our data and draw a conclusion to support our hypothesis

Hypothesis:In the woods room and metal rooms use wood preservatives and the janitors use cleaning products, then the VOC's would be higher in those areas due to the usage of them.

Variables:

Independent-Woods and Auto rooms, etc.

Dependent-VOC level and air quality

Constant-Time of day/where in the room we put the detector

Procedure:

1.Start first period after its cleaned

2.Test the woods rooms and metals rooms. For about a minute.

3.Collect our data from the rooms

4.Go to the metals rooms

5.Collect the data after 1 minute

6.Go to janitors closet and test the air

7.Collect our data

8.Test our control area

Hypothesis: If there is more CO2 released, then the air quality will lower.

Procedure:

1. (in classroom) Hold down power button on sensor for 5 second until screen lights up

2. Wait for the 120 second countdown to end

3. Place sensor in middle of classroom and let sit for 2 minutes

4. After 2 minutes, record the CO2 data located at the bottom of the screen (measured in PPM)

5. Repeat steps 1-5 in your experimental location (autos room) 

6. Record Data

7. Analyze any changes/fluctuations in data

Hypothesis:If we test the woods room for VOCS in the woods room then there should be a major increase in VOCS compared to the average classroom.

Variables:Independent:The area of the school

Dependent: The amount of VOCS

Constants: How long we test for VOCS,Where the sensor is going

1.Go to an average classroom which will not emit many VOCS as the control.

2.Test the VOCS within the classroom.

3. Go to the woods room to test an area with a higher amount if VOCS

4.Test the VOCS within the classroom

5. Test the art room for VOCS as well

6. Record the data for the rooms

Hypothesis: If the bathroom on the 1st floor will be in the red then, the 2nd and 3rd floor will be in the moderate range, and the 4th floor will be moderate to green. 

Variables: 

Independent: bathrooms on each floor 

Dependent: VOCs and air quality  

Constants: time (2 minutes) 

Procedure: 

• Grab air quality monitor and a chromebook 

• Go to first floor bathroom to test air quality 

• Wait 2 minutes for the air quality monitor or until it stabilizes 

• Go to 2nd floor bathroom to test the air quality 

• Repeat step 4 

• Repeat the same steps for the 3rd and 4th floor bathroom 

• Travel back to the classroom and compare data 

• Make a graph comparing the data and collect P-value

• Analysis

• Conclusion

Hypothesis:If a we compare floors for VOC levels then the 2nd floor will contain the most

Procedure: 

Start with first floor and measure the main hallway 

Then measure autos hallway (rooms with obvious amounts of VOCs also the lunch room)

2nd floor new wing test for engineering and woods room

Also test for culinary room 

Third floor test for art room and could test for Bio room class

On the 4th floor we will test the warrior room.

Accumulate all data given and compare averages

Determine which floor contained the most VOC’s

Hypothesis: If you open a window then the carbon dioxide level would decrease in the rooms.

Procedure: 1.Decide what rooms we will test

2.Write down what rooms we are gonna test

3.See if there are windows in the rooms

4. Look for Carbon dioxide sources

5.Test carbon dioxide levels

6.Compare carbon dioxide levels

Hypothesis: If we test that the wood and graphics room then graphics will have the highest Formaldehyde 

Procedure:

1.Go to woods room

2.Test the room in the middle and collect data 

3. Move to graphics room 

4. Test the room in the middle and collect data 

5. Compare the two collected and determine which one has the higher pollutant level

Hypothesis: If more products are used, then more VOCs will be present, therefore lowering the air quality.

Variables:

Independent: Amount of products

Dependent: VOC Levels

Constants: Empty Classroom/Outside

Procedure:

1 Create a table of all testing locations (Bathroom, Autos Room, Outside, Empty Classroom, Hallway, and Art Room) in your lab notebook, leaving a section for air quality readings. 

2 Go to each location and follow steps 3-5, repeating for every location. 

3 Close the door and any windows before testing. 

4 Walk to the approximate center of the room and hold the air quality detector in the air.

5 Wait for the numbers to stop fluctuating or measure for thirty seconds before recording the reading into the table created in step 1.

6 Once finished measuring and logging all readings, compare data between the locations with outside and an empty classroom, as they should demonstrate more neutral readings.

Question: What classroom in MCHS has the highest levels of formaldehyde?

Hypothesis: If formaldehyde is most present in building materials, then the room at MCHS with the most formaldehyde would be the wood room due to all the materials used.

Variables: 

Independent: Room Tested

Dependent: Formaldehyde 

Constants: Air Quality Detector

Procedure: 

1. Go to woods/medals room 

2. Use the Air Quality Detector for 60 seconds and record number

3. Repeat in the Culinary and Bio Med room

Hypothesis: If the room is carpeted then it’s likely to have higher VOC levels.

Procedure

:1. Set up a table for the different rooms to organize data

2.Turn on detector 

3. Start recording air quality in the first room (APES Classroom/constant) and record results into table

4. Move to the 4th floor area with carpeting and use detector to record air quality levels then record results into table

If we test the various rooms for VOC’s, then the pool room will have the highest VOC’s

Independent:rooms/air

Dependent:VOCs

Constants:the Air quality detector 

Scotty, Nathan and Lorilye

• Go to desired classrooms to test air quality for VOC

• Turn on the air quality tester and record the air quality levels for each one and orgainize it through tables 

• Repeat these steps until done with all desired rooms

• Go to a room that is known for not having much VOC and record that as a base 

• Concludde with the P value to see difference in air quality 

• Write Anaylsis and compare with hypothesesis

hypothesis: rooms that are more ventilated are going to have (on average) lower levels of air pollution.

Procedure:

1. look for rooms that are very well ventilated as well as rooms that are not well ventilated.

2. go to those rooms and test the levels of air pollution.

3. compare the levels between all the rooms tested.
