Experiment Versus Scientific Investigation

The video tutorial explains the differences and similarities between experiments and scientific investigations. It highlights that experiments involve changing variables to test a hypothesis, while investigations do not alter variables. Both processes use the scientific method, which includes steps like asking questions, conducting research, forming hypotheses, testing, analyzing data, and communicating results. The tutorial emphasizes that despite differences, both methods require similar skills and aim to answer questions and share findings.

What is a key difference between an experiment and a scientific investigation?

• Experiments change variables, while investigations do not.

• Scientific investigations are always conducted in a lab.

• Scientific investigations always use a control group.

• Experiments do not involve a hypothesis.

Which step of the scientific method involves gathering background information?

• Forming a hypothesis

• Conducting an experiment

• Asking a question

• Researching the topic

What is the purpose of forming a hypothesis in the scientific method?

• To communicate results

• To make an educated guess about the outcome

• To analyze data

• To change variables

During which step of the scientific method do you test the hypothesis?

• Analyzing data

• Conducting an experiment

• Communicating results

• Forming a hypothesis

How can results be shared after completing an experiment?

• By changing the hypothesis

• By altering the variables

• By creating a report or graph

• By conducting more tests
