Question

Provide an example of the components of an experimental design (ETCRRR) based off the following observation, hypothesis and prediction:

Observation: When hunting, cougars appear to avoid paths that take them directly in contact with farmhouses.

Hypothesis: The movement of cougars while hunting is related to the proximity of farmhouses because the ambient light given off by the farm houses reduces their ability to camouflage.

Prediction: As the amount of ambient light along a cougar hunting path increases, less cougars will use the path.

1. Steps in the scientific process:  

• step1:Ask a question.For the first step,help your child form a question ,hopefully one that can be answered!..
• step2:Do background research.
• step3:Construct a hypothesis.
• step4:Test your hypothesis by doing an experiment
• step5:Analyze the data and draw a conclusion
• step6:Share your result.
• HYPOTHESIS:If we increase the amount of light during studying,then the participants performance on test scores will decrease.
• STEPS OF THE SCIENTIFIC METHOD:
• OBSERVATION / RESEARCH
• HYPOTHESIS
• PREDICTION
• EXPERIMENTION
• CONCLUSION
• OBSERVATION:Isthe first step, so that you know how you want to go about your research.
• HYPOTHESIS:Is the answer you thick you'll find
• PREDICTION:Is your specific belif about the scientific idea:if my hypothesis is true,then i predict we will discover this.
• EXPERIMENTION:Is the tool that you invent to answer the question.
• CONCLUSION:Is the answer that the experiment gives.
• NULL HYPOTHESIS:A null hypothesis is a hypothesis that says there is no statistical significance between the two variables.It is usaually the hypothesisa research will try to disprove.
