Why should scientific investigations be replicable?
Why should scientific investigations be replicable?
- To ensure that the results are accurate (correct)
- To allow for different interpretations of the data
- To provide opportunities for collaboration among scientists
- To increase the complexity of the investigation

Study Notes
Scientific Investigations
- Carrying out a scientific investigation involves several steps, but guessing is NOT one of them.
Experiment vs. Other Investigations
- An experiment is a type of scientific investigation that involves manipulating a variable and measuring its effect on another variable.
- Other types of scientific investigations include observational studies, surveys, and case studies.
Replicability
- Scientific investigations should be replicable to ensure that the results are consistent and reliable.
- Replicability allows other researchers to verify the findings and increase confidence in the results.
Collaboration and Knowledge Sharing
- Discussing, comparing, and negotiating methods, results, and explanations among groups of students conducting the same investigation promotes collaborative learning.
- This process helps to identify errors, refine methods, and improve results.
Durability of Scientific Knowledge
- Scientific knowledge is considered durable because it is evidence-based and tested repeatedly.
- The repetition of investigations and the accumulation of evidence over time make scientific knowledge more reliable and long-lasting.
