It should look like this. |
|
Something to think about. |
|
Why was the lid inverted and returned to the top of the bottle? Why not leave it off? |
|
What purpose do the rocks serve? |
|
Why did we put water in the rain gauge? (Hint look at the bottom of the 2-liter bottle. How would you account for that irregular shape if you did not start with your water level above it?) |
|
How will you determine the amount of rainfall? This will require some math. (just a little, don't panic) |
|
You are ready to begin. |
|
|
Place the rain gauge away from buildings or shelter of trees. |
|
|
Check from time to time and measure the amount of rain fall. |
|
Cut the top off of the 2-liter bottle.
