What It Means

The experiment demonstrated is a powerful way to present evidence. It moves the focus away from your opinion. Instead, it puts the focus on the facts. When you use this, you are saying the proof is right there. It is not just a guess anymore. It is a proven reality based on a structured test. Think of it as the 'mic drop' of the scientific world.

How To Use It

You usually follow this phrase with the word that. For example, The experiment demonstrated that plants grow faster in sunlight. You can also use it to show a process. Try saying, The experiment demonstrated the effectiveness of the new drug. It sounds very professional and confident. Use it when you have data to back you up. Don't use it if you are just sharing a personal feeling.

When To Use It

This is a star player in academic writing and lab reports. Use it during a business presentation to show your strategy works. It is great for school essays or when explaining a complex idea. You can even use it at home if you did a 'test' on something. Maybe you tested which coffee brand keeps you awake longer. It adds a touch of authority to your findings. It makes you sound like a serious researcher.

When NOT To Use It

Avoid this phrase in very casual settings. Don't use it while grabbing a burger with friends. Saying The experiment demonstrated that I am hungry sounds like a robot. It is too heavy for light conversation. Also, do not use it if your 'experiment' was just a quick look. If you didn't actually measure anything, use I noticed instead. Accuracy is key here. Don't over-promise if the data is weak.

Cultural Background

In Western culture, we value empirical evidence and the scientific method. This phrase comes from the Enlightenment era when logic became king. It reflects a society that trusts data over tradition. In English-speaking universities, being 'objective' is a huge deal. Using this phrase shows you respect the rules of logic. It is a linguistic badge of honor for thinkers and doers.

Common Variations

You might hear The study showed or The data suggested. If the results are 100% certain, use The experiment proved. If you want to be a bit softer, try The results indicated. Each one changes the 'strength' of your claim slightly. Demonstrated sits right in the middle—it is firm but polite. It is the perfect balance for most professional situations.

使い方のコツ

This is a high-level academic phrase. It is perfectly suited for C1 level writing. Avoid using it in text messages unless you are being intentionally funny or dramatic.
