Simple Machines Worksheets for 6th to 8th Grade

What your child practices

This 6th to 8th grade science set (Grades 6 to 8 in Canada) explores Simple Machines through 6 worksheets and 59 questions. Middle school science builds models and explanations from evidence, and Simple Machines connects to ideas your child will meet again in high school. It opens with a guided Learn and Practice page, moves on to a practice sheet and a review test, then finishes with two quick quizzes and a mixed review. It is aligned to NGSS MS-PS2-2, which focuses on forces, motion and how objects interact. It also touches MS-ETS1-1, engineering design: defining a problem, testing ideas and improving them. In Canada it matches the BC curriculum for Grade 6. Answer keys sit on page 2 of each PDF, so checking takes seconds. Finished a sheet? The online version reads every question aloud and checks answers instantly.

Tips for parents

• Have your child connect the topic to a current news story or real invention.
• Let your child predict an answer before reading, then check if the prediction held up.
• Connect Simple Machines to something at home: the kitchen, the yard or the sky tonight.
