Replication in research means using the same method and methodology in proximity to the original research work.
It helps in bringing, validating and proving the original study is up-to-date. It may be done using the same exact methods in a different cultural settings, location or different research subjects to determine if the original experimental results is up-to-date.
After the worms have finished eating their food, the students must now weigh the worms and record this data. They can then compare these new weights to the starting weights of the worms and see if it demonstrates their hypothesis. Hope this helped :)
