Fourth grade science vocabulary is not only an important part of the science curriculum, but it is useful in enriching students’ general knowledge of science. Those who struggle with a science concept can become more comfortable with fourth grade science words through drill and practice. The repetition is required for students to feel confident with more complex and challenging definitions.

Vocabulary study through games and activities is a great way to bolster understanding. When students can apply meaning from key vocabulary definitions to real-life contexts, their grasp of fourth grade science becomes stronger. This provides the necessary basis upon which they can build their scientific inquiry and explore connectivity. Using the extensive, targeted elementary science word lists below, students can play science games, hear how the words are pronounced, and review knowledge acquisition through online testing. More beneficial than a traditional fourth grade dictionary, these lists include words relating to scientific method, life science terms, astronomy terms, and many more science concepts.

Categories are provided at a glance (see “Summary Lists” below) or in extended form in the following categories: Scientific Inquiry, Matter, Energy, Motion, Space, Earth, and Life Science. VocabularySpellingCity helps augment fourth grade science lessons by making the study of science words enjoyable and entertaining!
