Evidence suggests that bacteria supplied with a cup of sugar could run a 60-watt light bulb for 17 hours. What would a scientist need to do to be able to affirm this scientific idea?
is it to conduct an experiment to test the hypothesis
Yes.
ok thank you what about
Which variable does the scientists or you deliberately change? Dependent, Independent, control
is is independent
Which variable does the scientists measure? Dependent, Independent, control
is it dependent
6. Which variable remains the same/constant throughout the experiment? Dependent, Independent,
Control
is it control
7. When you create a graph of your results, the independent variable always goes on the ______ axis (is it x)
and the dependent variable goes on the ________ axis. (is it y)
Yes, conducting an experiment would indeed be the most appropriate method for a scientist to affirm this scientific idea. Here are the steps a scientist might take to experimentally test the hypothesis:
1. Formulate a clear and testable hypothesis: In this case, the hypothesis would be that bacteria supplied with a cup of sugar can run a 60-watt light bulb for 17 hours.
2. Design and set up the experiment: Determine the setup required to test the hypothesis. This would involve acquiring the necessary materials, such as a specific strain of bacteria, a 60-watt light bulb, an appropriate container, and a defined amount of sugar.
3. Prepare the experimental conditions: Create a standardized environment for the experiment, including temperature, lighting, and any other relevant factors. Ensure that all variables, other than the cup of sugar, are controlled.
4. Set up the measurement apparatus: Connect the light bulb to a power source or energy measurement device to accurately measure the amount of power consumed.
5. Introduce the sugar to the bacteria: Supply the cup of sugar to the bacteria in the chosen container under the specified conditions.
6. Monitor and record the results: Turn on the light bulb and measure the time it takes for the bulb to consume 60 watts of power. Continuously monitor and record the amount of time the light bulb remains lit until power consumption reaches 60 watts (or until it no longer functions).
7. Repeat the experiment: To ensure reliability and accuracy, repeat the experiment multiple times, keeping the experimental conditions consistent each time. This will help establish the consistency and validity of the results.
8. Analyze the data: Collect all the recorded data from the experiment, including the duration of time the light bulb remained lit in each trial, and any other relevant measurements or observations.
9. Draw conclusions: Analyze the data to determine if the results support or reject the hypothesis. Consider any inconsistencies, limitations, or sources of error. If the data consistently shows that the bacteria supplied with a cup of sugar can run the light bulb for 17 hours, it would support the hypothesis.
10. Communicate the findings: Present the experimental findings and conclusions in a scientific format such as a research paper, conference presentation, or by publishing the results in a scientific journal.
