Question: What is the difference between the amount of chemicals in an enclosed room vs a room with windows or ventilation

Hypothesis: If we go somewhere that contains formaldehyde, but has no windows, there will be a higher rate of the chemical.

Variables:

I: Window

D: Amount of formaldehyde

C: Testing in the middle of the room

1. o into the room

2. Set down the detector in the floor

3. Wait for the timer to go off

4. Check results and record it

5. Repeat steps 1-4 for each of the rooms

What areas within the school have the highest levels of CO2.

Hypothesis:We believe that in our school the areas with the highest amount of CO2 will be the Autos room, the metals room, rooms around areas that have furnaces, and sciences rooms that are using burners that day.

Independent Variable:Area that is being tested.

Dependent Variable:Amount of CO2

Constants:Same amount of time in rooms AND Look for the areas where CO2 will most likely be produced at the highest.

Procedure:

1. Walk into the classroom that is being tested

2. Turn on the detector

3. After the detector has been calibrated collect data for 1 minute

4. Write CO2 amounts down in a chart.

5. Repeat steps for the remaining classrooms.

Question: How do the VOC levels in the bathroom and autos room defer from VOC levels in a typical classroom?

Hypothesis: If we test VOC levels in the autos room and an average classroom, the autos room will have the highest VOC level.

Variables:

Independent - Classroom

Dependent- Air quality

Constants - Amount of time being tested

Procedure:

1. Gather materials: VOC sensor (charged), notebook, pencil, chromebook

2. Take the sensor out of the box

3. Begin testing VOC levels in the various rooms (environmental classroom, autos)

4. Test for 10 minutes in Environmental Classroom

5. Record data

6. Test for 10 minutes in Autos Room

7. Record data

8. Compare data, see which had the higher VOC level

9. Make table and graph that compares the 2 rooms

10. Conclude data, and reflect on hypotheses to see if it is correct or not.

Question:

How do building products that produce formaldehyde affect indoor air quality in school?

Hypothesis:

If we test classrooms that use building materials then formaldehyde levels will be higher.

Variables:

Independent: where we test

Dependent: formaldehyde levels

Constants: the device we use, how long we test

Procedure:

1.Test control classroom with formaldehyde detector (APES room)

2. Choose 3 other rooms to test (woods, autos, graphics)

3. Collect formaldehyde levels from each room for 2 minutes and perform 3 trials per room

4. Record data in data table and calculate average

What areas in the school have the highest CO2 concentration?

If more people are in a compact area with little ventilation, then the CO2 concentration will be higher.

Independent: The area in the school being tested

Dependent: CO2 concentration

Constants: Materials used, time to sit, orientation

1. Charge the air quality detector

2. Put the air quality detector in the tested rooms

3. Stand the air quality detector up

4. Turn the air quality detector on

5. Wait two minutes for results

6. Collect results write them down

7. Compare data and see which one has higher CO2 levels

8. Share and compare with other groups

Question:

If we test for Carbon dioxide, would it be more concentrated in the Autos room or the Woods room?

Hypothesis:

If carbon dioxide levels are tested in the autos room, then it will result in higher levels of carbon dioxide compared to the wood room.

Variables:

Independent: location

Dependent:amounts of carbon dioxide

Constants: location in the specific room for each trial, times tested, height of sensor

1. Go to autos room and set up air quality tester in corner on ground

2. Have it run until it stabilizes

3. Record data

4. Go to woods room and repeat steps 1-3

5. Test each room once more with the same steps in a different location within the room.

Question: How does the use of cleaning products and car emissions affect indoor air quality in the Autos shop?

Hypothesis: If students use cleaning products, and let cars run in the shop, then the air quality will decrease.

Variables:

Independent - car emissions and cleaner spray

Dependent - air quality

Constants - space/people in the shop, time

Procedure

1. Go to Autos room

2. Go to bench behind seating area

3. Set up quality monitor

4. Put air quality monitor on bench

5. Take a reading

6. Take at least three readings total

7. Collect date in chart

8. Compare readings

EXAMPLE

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.
