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.

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?

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?
