Science Vocabulary Building
Learning science vocabulary is essential for anyone who wants to communicate effectively in the field of science. It is also important for those who want to learn science in English. Building a strong science vocabulary can be challenging, but it is not impossible. In this section, we will explore some effective ways to build your science vocabulary.
Prefixes and Suffixes
One of the most effective ways to build your science vocabulary is by learning the prefixes and suffixes that are commonly used in science. Prefixes and suffixes are added to root words to create new words with different meanings. Here are some common prefixes and suffixes used in science:
Prefixes
| Prefix | Meaning | Example |
|---|---|---|
| Anti- | Against | Antibiotic |
| Bio- | Life | Biology |
| Geo- | Earth | Geology |
| Hydro- | Water | Hydrogen |
Suffixes
| Suffix | Meaning | Example |
|---|---|---|
| -logy | Study of | Biology |
| -meter | Measure | Thermometer |
| -scope | Observe | Microscope |
| -ology | Science | Geology |
Root Words
Another effective way to build your science vocabulary is by learning the root words that are commonly used in science. Root words are the basic building blocks of words, and they carry the main meaning of the word. Here are some common root words used in science:
| Root Word | Meaning | Example |
|---|---|---|
| Bio- | Life | Biology |
| Geo- | Earth | Geology |
| Hydro- | Water | Hydrogen |
| Photo- | Light | Photosynthesis |
Learning the meaning of these prefixes, suffixes, and root words can help you understand the meaning of many science words. For example, if you know that “bio” means life and “logy” means the study of, you can easily understand that “biology” means the study of life.
