Nature of Science : Lesson 1

Shawn conducted an experiment and did not get the results he was expecting. What should he do first?

• Shawn should write conclusions.

• Shawn should share his results.

• Shawn should explain what he thought should have happened.

• Shawn should check his experiment for errors and try again

In order to increase validity before publishing the research, the researcher should _________ the trials. In this published research, the author should be clear about the methodology so other researchers could ____________the experiment.

• independent, dependent

• Repeat, Replicate

• Replicate, Repeat

• Compare, compare

In order for a scientific investigation to be considered valid, the evidence produced by the investigation must be__________.

• in the form of a graph.

• a way to prove the hypothesis.

• replicable by others.

• conducted in a lab.

A scientist decides to replicate an experiment completed by another scientist. Which statement describes something that would not affect the results of the replicated experiment?

• The two scientists did not use the same equipment.

• The two experiments were completed by two different people.

• The variables were not kept the same in both experiments.

• There were some measurements that were different in the two experiments.

John wants to prove that the paved area of the playground is hotter than the grassy area of the playground. He measures the temperature of each area at three different times of the school day and records the temperatures. He does this for five days in a row. Thomas wants to replicate John's experiment. Which statement describes a situation that could cause Thomas's data to vary from John's data?

• Thomas measures the temperatures only on the sunny days.

• Thomas measures the temperatures of the paved area and the grassy area.

• Thomas records the temperature data on a chart.

• Thomas uses the same equipment that John used.
