Science
Scientific Method is a free printable science worksheet for students in Grades 6–8. It includes 10 questions—9 multiple-choice and 1 multiple-select—that build understanding of core scientific method vocabulary and experimental design. Students identify independent and controlled variables in a plant-growth investigation, define a hypothesis, recognize the scientific method as an organized process, select the metric system, and choose an appropriate tool for measuring the volume of rocks. The worksheet helps students connect definitions to applied examples instead of memorizing terms in isolation. The repeated plant investigation asks them to distinguish the variable changed by the scientist from conditions kept the same, while the hypothesis questions reinforce the idea of a research-based, untested explanation. Use it for guided practice, independent review, or a quick formative assessment. A complete answer key is included, and the worksheet is available as a free printable PDF.

This Grade 6–8 science worksheet uses 9 multiple-choice questions and 1 multiple-select question to assess scientific method vocabulary and experimental design. Students identify independent and controlled variables in a plant-growth investigation, recognize a hypothesis as an educated or untested explanation, identify the metric system, select a tool for measuring rock volume, and explain the scientific method as an organized way to answer questions.
Introduce the plant-growth scenario before assigning the worksheet, and ask students what changes between plants and what remains the same. Have them justify why the type of liquid is the independent variable and why conditions such as soil, sunlight, and music are controlled variables. Then use the hypothesis items to discuss why a proposed explanation must be formed before testing rather than treated as a proven result.
Students may confuse the independent variable with a controlled variable by selecting a condition kept the same instead of the type of liquid that changes. They may also treat a hypothesis as a correct answer or an experiment result rather than an educated, untested explanation. On the multiple-select item, check that students select both applicable descriptions instead of choosing only one.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, with a complete answer key for all 10 items. You can grade printable submissions by scanning student work with the Wayground for Teachers app. The printable format also gives schools an option for reducing screen time while students review variables, hypotheses, measurement, and the scientific method.
In the worksheet’s Advanced Settings, adjust font spacing and font size to make the scientific method definitions and plant-investigation scenarios easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options better support access to the vocabulary-heavy multiple-choice and multiple-select items.
