7) In addition to what you saw, did you detect any smells? Describe them. At what point in the observation process did you detect them?
Yes. In a little far distant I smell only gasoline when the car driven around and also when filling gasoline to my car.

8) If you used the candle, what color was the molten wax? If you looked at something in the environment (a dog, bird, the sky, clouds), provide details...color, texture, shape, size, etc.

I believe the candle contains carbon and hydrogen atoms. When we burn the candle these two elements react with the oxygen on the air burns the candle. So based on my experiment the yellow can have molten wax. So if I looked outside the environment lots of animals live in the atmosphere. The dog, bird, the sky and clouds are all live on the same athmosper.sky could be blue and may represent the bottom part of the candle, the bird is small animal and clouds are white and carry hydrogen atom.

9) Describe any patterns you observed. (the smoke from the extinguished candle, the movement of the clouds for the environment activity, etc.).

10) If you observed the candle, was the color transition of blue to yellow in the flame gradual or abrupt? 11) Sketch a simple image of what you observed.

12) What other questions would YOU ask to be sure your observations were adequately described?

13) How could you use your observations?

14) What equipment could you have used to make even better observations?

15) How would these two observation activities (‘listening’ and ‘seeing’) relate to science?

    I am sitting just before the escalator to go upstairs to the food court and movie theater. I am sitting on a wooden bench with my girlfriend to my left. There are many shops surrounding me such as Champs, Pacsun, Traffic, Lids, Home Elements and Dollar Tree. The area that I will be observing is about 50 feet by 100 feet. There are 4 potted trees around me, one to my direct left, one to my direct right, one northeast and one northwest. There are also two fake plants directly north of me in between the two potted trees. There are two sets of stairs on each side of a long ramp to my left. As I look up, there is a large sunroof approximately 200 feet above me. It is sunny out today with few thunderstorms. It rained about 2 hours ago but has since brightened up and evaporated all of the water which means it is very humid outside. There is constant foot traffic inside the area that I am observing today.…
