                                                   Insulative Quality of Air

                                                 --The Effect of Moving Air on The Natural Convection of Air

Methodology 

  1. Data Need To Be Measured
I--Water temperature as one way of tracking how the currents move around.
II--Visualization of currents movements under different speed of moving water.
      2.  Means of Measuring
Picture
I--Laser cutter was used to cut acrylic board making the box to hold water.
II--Water temperature sensor functioning with Elegoo Uno R3, Bredboard, Arduino to measure the changing water temperature.
III--A Peristaltic Liquid Pump with Silicone Tubing was used to move the water in plexibox.
      3. Consistent Results
I--Renew the water after every round of experiment with the same water temperature.
II--Keep everything else in the same place in every round of experiment, including the location of ink, the distance from heating source,etc

Plans To Adapt and Repeat

Issues Description:
The heating lamp is not efficient enough to heat the water in a relatively short amount of time(10 ​minute)
Repetition
More rounds of experiment should be conducted with a series of speed of moving water.

Experiment I
Picture
 Video I
Experiment Observation I
Fill the small pelxiglass box with hot water at 42.4 0/C and keep it still. The ink moves slowly towards hot water, then it starts movement about 4 minutes later. 
The temperature goes down from 42.4
0/C to 40.20/C in 5 minutes.
Experiment II
Picture
​Video II
Experiment Observation II
Fill the small pelxiglass box with hot water at 42.4 0/C and keep it still. The ink moves faster than that in experiment I towards hot water, then it moves very slowly after 4 minutes.
The temperature goes down from 42.40/C to 37.20/C in 5 minutes.
Experiment III
Picture
​Video III
Experiment Observation III
​Fill the small pelxiglass box with hot water at 42.4 0/C and keep it still. The ink moves faster than that in experiment II towards hot water, then it moves very slowly after 4 minutes.
The temperature goes down from 42.40/C to 35.20/C in 5 minutes.
