The video tutorial introduces the concept of a fair test, a method to investigate scientific questions. It outlines the steps to conduct a fair test, including asking a scientific question, planning the test, and identifying necessary equipment. The importance of changing only one variable at a time is emphasized. The tutorial also covers how to record observations and draw conclusions from the results. Finally, it encourages viewers to ask further questions and conduct new investigations.

What is the primary purpose of a fair test in scientific investigations?

• To ensure the experiment is fun

• To investigate scientific questions accurately

• To use as many variables as possible

• To make the experiment complex

What is the first step in conducting a fair test?

• Choosing the equipment

• Analyzing results

• Formulating a scientific question

• Collecting data

Why is it important to change only one variable at a time in an experiment?

• To make the experiment more interesting

• To use all available equipment

• To ensure accurate measurement of effects

• To make the experiment faster

Which of the following is NOT typically used in a scientific experiment?

• Beaker

• Test tubes

• Conical flask

• Biceps

What should you do after observing changes during a fair test?

• Start a new experiment

• Change multiple variables

• Record the observations

• Ignore the changes

How can data from a fair test be represented?

• In a song

• In a paragraph

• Using a table or chart

• Through a story

What is the purpose of drawing a conclusion in a fair test?

• To end the experiment

• To start a new test

• To answer the scientific question

• To confuse the results

What question should you ask to evaluate the reliability of your test results?

• Did I change all variables?

• Did I use enough equipment?

• Was my test a good test?

• Was the experiment fun?

If you have new questions after a fair test, what should you do?

• Ignore them

• Conduct a new investigation

• Change the old results

• Ask someone else to do it

What is a key characteristic of a fair test?

• Keeping all variables constant

• Not recording observations

• Changing multiple variables

• Changing one variable at a time
