1. Observe
g) A scientist observes that a pond adjacent to an industrial plant has heavier algae growth than ponds farther away.
Reason: The scientist is using their visual skills to collect information/ data.
2. Ask a question
c). A scientist wonders if the waste water emitted from an industrial plant is accelerating the growth of algae in a pond.
Reason: The scientist is asking themselves a question from which they can base a study.
3. Create a hypothesis
a) A scientist, based on his observation of the pond, believes that if a pond is exposed to the waste of an industrial plant, then the growth of algae will be accelerated.
Reason: The scientist makes a prediction on how to accelerate the growth of the algae which is a hypothesis.
4. Conduct an experiment
b). In her laboratory, a scientist pours a vial of waste water, collected from the industrial plant, and adds it to a dish containing pond water. A second dish (the control dish), containing the same pond water, does not receive the waste water sample.
Reason: The scientist is carrying out a methodical activity to clarify whether their hypothesis was true or false.
5. Collect data
d) After 5 days, the scientist measures the amount of algae present in each dish.
Reason: The scientist is collecting unprocessed information from the results of their experiment.
6. Interpret Results
f) After the data is collected, the scientist discovers that the dish containing both the pond water and waste water had more than twice the amount of algae than the control dish.
Reason: The scientist makes a conclusion based on data from their experiment.
7. Report Results
e) The scientist submits his findings to a scientific journal.
Reason: The scientist shares their research data and results with other people.
