The Effect of the Time of the Day

on the Level of Air Particulates


2/20

Significance of Study and Objectives

A study in Nigerian cities say that airparticulates there caused an increase inhospital admissions due to respiratory

and heart disease. The researchers objectives are:

To determine the effects of the time ofthe day on the mass of the airparticulates.

To get a conclusion that will hopefullyget more knowledge about improvingthe air condition in the Philippines.


3/20

Problem Statement

In declarative form, the aim of this

study is to know if the time of

day affects the level of airparticulates.

In question form, does the time of

day affect the level of airparticulates?


4/20

Hypothesis

The time of day

does not affect thelevel of air

particulates.

Analysis ofData (Relationship of

Variables)

Based on the data collected, the

time of day does not affect the

amount of air particulatescollected by the lenses. The

researchers say this because the

average amount of airparticulates collected are only

different by 0.002 grams


10/20

Analysis ofData (Sources of

Err

or)

The researchers could have

not been precise on the

duration of the lens to airparticulates.

The researcher could havenot put the same amount of

petrolleum jelly on the lenses.


11/20

Set-up Design (Actual Design)

A lens with petrolleum jelly wasput on a windowsill exposed to

air particulates for four hoursfrom 8 a.m. to 12 p.m. and 4p.m. to 8 p.m. on 5 Saturdays.They were measured thefollowing Monday using a cent-o-gram balance.

14/20

Set-up Design (Procedure)

Label one lens with day and the other

with night.

Get the mass of one lens and record it.

At 8 a.m. on a Sunday, put petroleum jelly

on the day lens and put it on a window

sill.

At 12 p.m. on the same day, retrieve thelens, get its total mass and record the data.

Subtract the data received in step 2 from

the data received in step 4 to get the mass

of the air particulates.


15/20

Set-up Design (Procedure cont.)

At 4 p.m., put petroleum jelly on thenight lens and put it on the window sill.

At 8 p.m., retrieve the lens, get its total

mass and record the data. Subtract the data received in step 2 from

the data received in step 7 to get themass of the air particulates.

Wash and dry the lenses.

Repeat steps 3-9 four more times on fourmore Sundays to make 5 trials in-all.

Make a table and put data there


16/20

Set-up Design (Variables)

Independent Variable the time

of day

Dependent Variable the massof air particulates

Controlled Variables

the mass of lens, the amount ofpetroleum jelly used, the location

of the set-up


17/20

Conclusion

The researchers therefore

conclude that the time of day

does not affect the mass of airparticulates.

Although, the data is insufficient

because the researchers thinkthat two set-ups are not enough

to prove the conclusion to be

correct.


18/20

Recommendations

The researchers could do

more trials.

They could get more lensesfor the experiment.

They could have held a 12p.m. to 4 p.m. set-up.
