Exploring the Scientific Method in JR High School Science

What are the three types of variables discussed in the video?

• Independent, Dependent, and Random

• Fixed, Variable, and Random

• Controlled, Random, and Fixed

• Independent, Dependent, and Controlled

In the gardening experiment example, which variable is being tested?

• Amount of sunlight

• Type of soil

• Type of plant

• Amount of water

Why is it important to keep controlled variables the same in an experiment?

• To change the outcome of the experiment

• To make the experiment more complex

• To ensure the experiment is fair

• To reduce the number of variables

Which of the following is an example of a controlled variable in the gardening experiment?

• Height of the plant

• Growth of the plant

• Type of soil

• Amount of sunlight

What is the independent variable in the gardening experiment?

• Amount of sunlight

• Type of plant

• Amount of water

• Type of soil

How can you remember what an independent variable is?

• It is the variable that stays the same

• It is the variable that is controlled

• It is the variable that is measured

• It is the variable that I change

What is the dependent variable in the gardening experiment?

• Amount of water

• Type of soil

• Type of plant

• Growth of the plant

Why is the dependent variable called 'dependent'?

• Because it is chosen by the scientist

• Because it depends on the independent variable

• Because it depends on the controlled variable

• Because it is always the same

What is the purpose of having only one independent variable in a good experiment?

• To make the experiment easier

• To ensure the results are due to one factor

• To make the experiment more interesting

• To increase the number of variables

In the context of the video, what is the main reason for controlling variables?

• To make the experiment more complex

• To ensure fairness and accuracy

• To change the outcome

• To reduce the number of variables
