    • 10. Evidence - Facts, information, or signs that show clearly that something is true or exists. Example: The police and scientists found evidence that the animal was in the forest.
    • 11. Measure - To discover the exact size, amount, or speed of something using a special tool. Example: Please use the ruler to measure the length of the paper in centimeters.
    • 12. Conclusion - The final result or opinion you form after carefully thinking about all the information and facts. Example: What conclusion did you reach after you finished your science project?

    How to Use Science Words in Everyday Conversations

    You might ask, "When will I use these words?" The answer is: very often! People talk about science more than they realize. For example, when you read about a new medicine, you are reading about research and discovery. When you check your fitness tracker, you are looking at data.

    Here is a short example of a conversation using some of our new vocabulary:

    Anna: Did you read about the new space discovery?
    Ben: Yes! Scientists did a long experiment and found evidence of water on Mars.
    Anna: That is amazing. They must have a lot of data to analyze now.
    Ben: Exactly. Their conclusion is very interesting.

    As you can see, you can easily use these words in a normal chat with your friends or your English tutor on See Guru.

    Tips to Remember New English Vocabulary

    Learning new words is great, but remembering them can be hard. Here are some simple tips to help you remember this science vocabulary:

    • Write them down: Keep a special notebook for new English words. Write the word, the meaning, and your own example sentence.
    • Watch science videos: Watch simple science videos on YouTube. Turn on the English subtitles. You will hear words like observe, measure, and theory many times.
    • Practice with a tutor: The best way to learn is by speaking. Find a private English tutor on See Guru. Tell your tutor you want to practice talking about science.
    • Use flashcards: Create small cards with the English word on one side and the definition on the other side. Test yourself every day.

    Science and the Passive Voice

    When you read about science in English, you will notice something special about the grammar. Scientists love to use the Passive Voice. We use the passive voice when the action is more important than the person who did it. In science, the experiment is usually more important than the scientist!

    Let's look at the difference:

    • Active Voice: The scientist measured the temperature. (Focus is on the scientist)
    • Passive Voice: The temperature was measured. (Focus is on the temperature and the action)

    To make the passive voice, we use the verb "to be" + the past participle (verb 3). For example: The data is analyzed or The discovery was made. Try to notice this grammar rule the next time you read a science article!

    Conclusion

    Learning science vocabulary does not have to be boring or difficult. By learning these 12 essential words, you are taking a big step in improving your English. You can now talk about experiments, share interesting facts, and understand new discoveries. Remember to practice these words in your writing and speaking.

    Frequently Asked Questions (FAQ)

    How can I learn English science vocabulary quickly?

    The fastest way to learn is by using the words in real conversations. Write your own sentences, watch simple science documentaries with English subtitles, and practice speaking with a private tutor on See Guru.

    Do I need an advanced English level to talk about science?

    No, you do not! You can talk about science using simple B1 level vocabulary. Words like "experiment", "data", and "research" are easy to learn and very common in everyday English.

    Why do scientists use the passive voice in English?

    Scientists use the passive voice because the action or the result is more important than the person doing it. It makes the writing sound more objective. For example, saying "the data was analyzed" focuses on the data, not the researcher.

    Grammar Tip: Using the Passive Voice in Science

    In scientific English, we often use the Passive Voice. We use it when the action or the result is more important than the person who did the action.

    To form the passive voice, use the verb to be + the past participle (Verb 3).

    • Active: The scientist measured the water.
    • Passive: The water was measured.

    Notice how the passive sentence focuses on the water instead of the scientist. Try using the passive voice when you talk about your next science project!
