Answer:
Explanation:
Scientific Research is a method used in the construction and testing of a scientific hypothesis.
It has six steps that can be used in solving questions ask or observations made which is A family wants to test the effectiveness of a misting shower head in conserving (saving) water compared to their regular shower head.
Steps to follow:
Make an observation: An observation would be made on how water is been used in the house and how it can be conserved, this observation is what brings about the question asked
Ask a question : The question is
which is more effective in conserving water a misting shower head or regular shower.
Form a hypothesis, or testable explanation: An hypothesis is formulated for the question asked
Example: Null hypothesis: Mistling shower conserves more water than shower head
Alternative: Mistling shower conserves less water that normal shower.
Make a prediction based on the hypothesis: Predictions are made on what could be the cause if there is indeed a difference and what could cause the difference
Test the prediction: An experiment is conducted to test the hypothesis if indeed Mistling is better than normal shower, the appropriate method is determined to be used for the experiment.
Iterate: The result gotten helps to butters our hypothesis if its to be acceoted or rejected. If rejected further research can be conducted on the effectiveness of normal shower in conserving water.
