Try these first

1. 1.

   What is the definition of a sample in environmental studies?

   Hint

   Think about how samples are used to represent larger environments.

2. 2.

   What does TSS stand for?

   Hint

   Consider what measurement relates to solid particles in liquids.

3. 3.

   What is the key formula for calculating concentration?

   • C = M/V
   • V = M/C
   • M = C/V

   Hint

   Recall the relationship between mass, volume, and concentration.

4. 4.

   Is a sample defined as a larger volume of a body or a portion of it?

   • True
   • False

   Hint

   Think about what represents the whole in sampling.

5. 5.

   If you needed to analyze particles in a liquid sample but your scale could only detect down to 0.5 mg, how would you adjust your sampling volume if you expected a concentration of 0.1 mg/L?

   Hint

   Consider the relationship between concentration and total mass.

6. 6.

   Describe the impact of unfiltered water versus filtered water sample readings for TSS when presented in a study.

   Hint

   Consider how filtration affects accuracy.
