Other Science Vocabulary Practice

Scientific Method Vocabulary discusses the main steps in the scientific method: identifying a problem, forming a hypothesis, planning an experiment or other way to test it, keeping a record of the experiment and observations, and analyzing and reporting the results. The page also discusses key vocabulary involved.

Climate Change and Weather Vocabulary discusses weather and climate in detail and has a practice exercise.

The Research and Scientific Words Quiz mostly practices general academic vocabulary that is also important for understanding scientific research: words like formula, implication, outcomes, and principles. 

There are other related pages (practicing both science AND general academic terms) linked from the EnglishHints Sitemap Science Vocabulary section.

There is a lot more scientific vocabulary than I have been able to teach on EnglishHints, however. See the Thought Company Science section that goes into the specialized vocabulary of physics, chemistry, biology, and other sciences that isn’t explained on EnglishHints.
