Fascinating Fact:

Hypothesis is a sensible idea you can test, for example plants grow faster when they get more light.

In KS3 English, you will meet science words in reports, articles, and exam questions. Understanding key terms helps you follow methods, interpret results, and write clear, concise conclusions.

  • Hypothesis: A testable idea that predicts what will happen in an investigation.
  • Variable: Something that can change in an experiment, such as light level or temperature.
  • Conclusion: A short statement explaining what the results show and whether the hypothesis was supported.
What does variable mean in a science investigation?

In science, a variable is a factor that can change. You usually change one independent variable, measure a dependent variable, and keep control variables the same.

What is the difference between method, results, and conclusion?

The method explains the steps you follow, results present the data you collected, and the conclusion interprets the data to answer the question.

What does reliable mean when describing an experiment?

Reliable means the results are consistent. Repeating tests, averaging readings, and controlling variables make findings more trustworthy.
