Question

A student wants to study how exposure to water for 24 hours affects bacterial growth

Which is an appropriate step of scientific inquiry that the student should complete?
Make several guesses about the effects of water on bacterial growth
Observe normal bacterial growth for 24 hours,
Ask a teacher what he or she thinks about bacterial growth
Collect data from other experiments on bacterial growth

Answer 1

Observe normal bacterial growth for 24 hours,

Step-by-step explanation:

• A student who wants to study how exposure of water can affect bacterial growth should firstly investigate that what is the normal bacterial growth for 24 hours (control) in the lab and then can compare the results with the water-exposed treatment (treatment).

Making guesses are good for hypothesis formulation but the generate a conclusion an experiment should be conducted.

Likewise, asking a teacher can help design an experiment but to be a researcher, the student should conduct the experiment in the lab.

Finally, collecting data from other experiments would not help understand the bacterial growth on specific conditions (water exposure) set for the experiment. Rather, the student should strictly conduct the experiment with the set criteria.
