Science is an awe-inspiring subject that encompasses many topics from astronomy to earth science. Faced with the vast array of first grade science terminology that is used, students can gain a comprehensive understanding of science by making connections between first grade science vocabulary and real life contexts.

Using first grade science games for online review along with targeted science worksheets and automated testing allows students to make the vital connection between science and application. The activities are designed to instill an understanding of the word definitions through quizzing, drilling, and repetition. Familiarity with a term’s spelling and meaning plays an important role in understanding its function in science and linkages to other areas.

VocabularySpellingCity has developed extensive elementary science word lists to enable students to make this connection. You have the option to browse the summary lists (see “Summary Lists” below) at a glance, or to view the extended versions in the following categories: Scientific Inquiry, Matter, Energy, Motion, Space, Earth, and Life Science.

The word lists are designed to fit the standard 1st grade science curriculum, and to cover a wide range of topics. Learning to use and understand vocabulary words from these science areas at the first grade level is key for students to advance to second grade science and beyond. Interactive first grade science activities make learning science awesome!
