Question

1. brayden is testing golf balls. he drops three different golf balls from the roof to see how long it takes them to hit the ground. he then drops each ball 10 more times and records their time. directions: use this article from ck - 12 to answer the questions below about replication. support your answer with evidence from the text. 7. why is it important to replicate an experiment? 8. why can it be difficult to replicate an experiment? 9. what happens if different results are concluded when the experiment is replicated?

Explanation:

• Q7: Replicating an experiment helps verify results. It checks if findings are consistent across multiple trials, reducing the impact of random errors or chance events. For example, in Brayden's golf - ball experiment, multiple drops help ensure the time - to - ground results are reliable.
• Q8: It can be difficult to replicate an experiment due to differences in experimental conditions. Even small variations in factors like temperature, humidity, or the exact way an instrument is used can lead to different results. Also, differences in materials (even if they seem similar) can play a role.
• Q9: If different results are concluded when an experiment is replicated, it may indicate problems with the original experiment or the replication. It could mean there were uncontrolled variables in the original, or errors in the replication process. Further investigation is needed to determine the cause of the discrepancy.

Answer:

• Q7: Replicating an experiment is important to verify results and reduce the impact of random errors.
• Q8: It can be difficult to replicate an experiment due to differences in experimental conditions and materials.
• Q9: If different results are concluded when an experiment is replicated, it may indicate problems with the original experiment or the replication, and further investigation is needed.
