Seventh grade science is where students really need to put on their thinking caps and understand the subjects on a deeper level. Learning science concepts can be easy and fun for seventh grade science students when they study their science vocabulary words by playing interactive online games. Students who learn the vocabulary that accompanies a specific subject are more likely to comprehend and excel in that subject. The study of science vocabulary for the seventh grade science curriculum is no exception.

VocabularySpellingCity provides extensive middle school science word lists, allowing students to study and review the most common seventh grade science words assigned by teachers. By using interactive and engaging science games, seventh grade students can master word meanings and use online testing to assess their learning and get immediate feedback.

Seven categories are covered, both at a glance (see “Summary Lists” below) and in depth: Scientific Inquiry, Matter, Energy, Motion, Space, Earth, and Life Science. Learning to use and understand vocabulary words from these science areas at the seventh grade level helps students as they advance to eighth grade science and beyond.

The games and activities are an engaging way to complement the middle school science core curriculum. Students can access these targeted science vocabulary lists below to see just how much fun learning science concepts can really be!
