1.2 Repetition and Replication (Wed)

​Repetition and Replication of Scientific Experiments

Multiple Choice

What is the benefit of another scientist replicating a science experiment?

• increases the number of people who can see the research

• Confirms the validity of the experiment and the research behind it

• Increases profit for the scientists

• Increases the opportunity for government funding for experiments

Multiple Choice

You designed a boat that is supposed to float, but every time you test the boat on the water, it sinks. Your results are unusual. What could you do next after you analyze your results?

• Continue to make boats with your design

• Publish an article on your results

• Use your data to make a new hypothesis

• Contact other scientists to replicate your experiment and compare results

Multiple Choice

In 2022, scientists want to replicate an experiment done in the Amazon Rainforest back in 1975. What do the scientists need to do to make sure they get similar results to the original 1975 study?

• Find errors in the 1975 study and research other similar experiments

• Assume they will do everything correctly and do the experiment quickly

• Replicate the 1975 study using the exact same variables to make sure their results are accurate

• Change the variables in the new experiment to make sure they get the results they want

Lab Directions

1. Pay attention to me while I show you the steps of the experiment

2. Each table can come up to the front to replicate the experiment using all of the same variables

​

Replication- when other scientists repeat your experiment in their lab to confirm the validity of your experiment

-must use the exact same variables

-helps confirm the validity of your results
