Think of observation then form a question and hypothesis. Then,
design an experiment you could do to test your hypothesis. Make
sure the experimental design is detailed and define all of your
variables (the dependent variable, the independent variable, the
controlled variable, designing the procedure, level of treatment,
replication, the control. )

Use the following hypothetical situation to answer the Part C. questions. You live along the Paulinskill River in a rural area of New Jersey known for its growing agriculture industry. This area was also once known for its large bog turtle population. In the last few decades, however, the bog turtle population has decreased to the point that this species is now considered critically endangered. You want to design an experiment to aid in the recovery of the bog turtle...
