- C.
Prototype
- D.
To do list
Correct Answer
B. ProcedureExplanation
The step by step directions for a lab activity are called the procedure. A procedure outlines the specific steps and instructions that need to be followed in order to complete the lab activity accurately and safely. It provides a clear and organized plan for conducting the experiment or activity, ensuring that all necessary actions are taken in the correct order. A procedure helps to ensure consistency and reproducibility in scientific experiments and activities.Rate this question:

Researchers at a the Cleveland Museum of Natural History have noticed that there are fewer dragonfly larvae in the feeder creeks of the Rocky River Reservation. Which of the following would be a testable hypothesis to explain this:
- A.
If pH levels in the water are higher because of pollution and there are too many frogs in the water, then there will be fewer larvae
- B.
If there is a drop in water temperature then dissolved oxygen levels will also drop and this will kill off larvae
- C.
Larvae don't like to live on the west side of the Rocky River
- D.
Larvae like to eat small insect eggs
Correct Answer
B. If there is a drop in water temperature then dissolved oxygen levels will also drop and this will kill off larvaeExplanation
If there is a drop in water temperature, it can lead to a decrease in dissolved oxygen levels. This decrease in dissolved oxygen can be harmful to the larvae, potentially killing them off. This hypothesis suggests that the change in water temperature is directly impacting the survival of the dragonfly larvae.Rate this question:

- A.
Conclusion
- B.
Data Collection
- C.
Observation
- D.

The independent variable in an experiment is the variable that is:
- A.
Controlled by the experimenter
- B.
Effected by the experiment
- C.
Not effected by anything anyone does to the experiment
- D.
Variable that can be left out of the experiment
Correct Answer
A. Controlled by the experimenterExplanation
The independent variable in an experiment is the variable that is controlled by the experimenter. This means that the experimenter has the ability to manipulate or change the independent variable in order to observe its effect on the dependent variable. By controlling the independent variable, the experimenter can determine the cause and effect relationship in the experiment.Rate this question:
