Science is one of the most extensive subjects that second graders will study, with many varying subcategories and multifaceted elementary science vocabulary words. Making connections between second grade science concepts and the vocabulary that supports and describes them plays an undeniable role in learning and appreciating science.
Students can understand and evaluate these linkages easily at VocabularySpellingCity. Comprehensive second grade science curriculum lists have been developed to include the most common terms used to teach classroom science concepts. Students have the opportunity to have the words read to them, to play second grade science games, and to test their understanding online.
The seven categories below are available either 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. Learning to use and understand vocabulary words from these science areas at the second grade level is key for students to advance to third grade science and beyond.
The activities available here will guide students in grasping the most complex terms by providing them with a fundamental understanding of their definitions. When students use animated interactive games to study essential second grade science terms, science is fun!
