Question: what factors contribute to different levels of CO2, VOC'S, and formaldehyde?

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.

4. decide if hypothesis is true.

How does the use of VOC products affect the indoor quality at McHenry High School?

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

Research Question: How does the concentrated use of everyday sources for VOCs affect air quality indoors?

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.

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

Question: How does indoor air pollution affect the air quality between each bathroom on different floors of the school?

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

Question:How does cutting and painting wood affect the VOC’S within the school?

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

?: How does the amount of CO2 released from car emissions affect air quality?

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)

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.

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.
