Semester 1 Review - Part 1

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

How can a hypothesis be tested effectively?

Back

A hypothesis can be tested by conducting experiments and observing the outcomes, such as measuring the time it takes for ice cubes to melt in different conditions.

Front

Why is it important to document observations immediately in an experiment?

Back

Documenting observations immediately helps ensure accuracy and reliability of the data collected during the experiment.

Front

What is a suitable method for visually representing data?

Back

A bar graph is a suitable method for visually representing data, such as monthly sales figures.

Front

What logical question can be explored based on an observation?

Back

A logical question to explore is how temperature influences the scratching behavior of dogs during summer.

Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a standard for comparison, helping to isolate the effects of the independent variable.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables.

Front

What is the importance of repeating experiments?

Back

Repeating experiments increases the reliability of results and helps confirm findings.
