Science

This Grade 6 science midterm review worksheet uses 23 multiple-choice, sentence-completion questions to reinforce key Earth and life science vocabulary. Students identify evolution, extinction, mass extinction, the Mesozoic and Cenozoic eras, major developments during geologic time, and the relationships among erosion, deposition, sediment, mass movement, and gravity. The format asks students to select the term that correctly completes each statement, making it useful for checking recall and distinguishing closely related concepts. Use this free printable worksheet with an answer key as independent practice, a review activity before a science assessment, or a quick diagnostic of students’ understanding of geologic history and surface processes. The completed items can help teachers identify whether students recognize definitions and connect each process or event with its correct term, era, or time period.

FAQs

What does this Grade 6 science worksheet cover?

This worksheet reviews evolution, extinct organisms, mass extinction, the Mesozoic and Cenozoic eras, and Earth-surface processes such as erosion, deposition, sediment, mass movement, and gravity. Its 23 multiple-choice sentence-completion items help students select the precise term, era, or process that completes each statement.

How can I use this worksheet to teach geologic eras and erosion processes?

Introduce the review by grouping the items into two discussions: geologic history and surface processes. Have students explain why terms such as Mesozoic era, Cenozoic era, mass extinction, erosion, deposition, and mass movement fit their statements, then use the worksheet for guided practice before independent completion.

What mistakes should I watch for when students complete this worksheet?

Students may confuse related terms such as erosion, weathering, deposition, and mass movement, or choose sediment instead of the process that moves or deposits it. They may also mix up the Mesozoic and Cenozoic eras, confuse an era with a period or epoch, or select dinosaurs when a statement specifically describes mammals.

How do I assign and grade this worksheet?

On Wayground, assign this worksheet as a printable PDF or as a digital quiz, and use the complete answer key to check responses. Printable submissions can also be graded by scanning student work with the Wayground for Teachers app.

How can I differentiate this worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing and font size for the multiple-choice sentence-completion items. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options better support access to the science vocabulary.
