15. A student made this entry in her notebook:
5/5/2005- We are doing an experiment to determine if the size of soil particles affects the amount of
water that flows through soil. We poured 100 mL of water through four different types of soil. The equipment
is shown below.
We got the following results: With gray soil, the average particle
size was 2.0 millimeters (mm) and 80 mL of water flowed through.
We then used tan soil. Its average particle size was 0.5 mm and 40
mL of water flowed through. With brown soil, 60 mL of water
flowed through. Brown soil has an average particle size of 1.5 mm.
In our last trial we used black soil. It has an average particle size of
1.0 mm and 50 mL of water flowed through.
a. Using the data table below, organize the results to show the average particle size and the amount of water
that flowed through for each type of soil. Be sure to include column headings, data, and units in the table.

*Base your answers to questions 16-17 on this passage. A student adds sugar to a cup of iced tea & a cup

correct.
