Q: Name five things that are important to keep in mind when you are maintaing your legally definsible notebook?
Feedback: 1.Make sure to write in ink that can not be dissolved or erased and not pencil. This is meant to be a permanent record! 2.Use one notebook for everything, graphs, calculations, notes, etc. 3.Make sure to write you initials and date on every page. 4.If you make mistakes and need to omit them, cross them out with a single line that can still be read. 5.Every time that something is changed or omitted you need to initial and date it, i.e. think of it when you sign a contract, a lease or any legal document, you initial and date it several times.

Q: Define standard error and why it is important to recognize.
Feedback: Standard error is the standard deviation that accounts for your sample size, i.e. the larger your sample size the smaller your standard error will be and vice versa.

Q: What is this and what is it used for?
Feedback: Aqueous sampling is typically collected into small containers for future analysis.

Q: What is this and what is it used to sample for and why?
Feedback: Sampling plankton can be crucial in understanding if a certain compound is a bioaccumulate (a compound that builds up in the environment). Many of the worst environmental disasters were from a bioaccumulate, e.g. DDT a pesticide from the mid 20th century that contributed to the weakening of bird shells killing the young before they were born or Atrazine an herbicide that contaminated water supplies that led to the feminizing of frog species and shifting the sex ratios.
