Scientific Investigations & Design gives Grade 6 Science students focused practice turning observations into investigable questions and using evidence to investigate problems or improve designs. Designed for the Texas Science 6: Investigations, Evidence and Systems topic and TEKS framework, this resource connects scientific inquiry with practical engineering design.

From Observation to Investigation

The reading passage shows how an observation, such as seedlings leaning toward a window, can lead to an investigable question. Students distinguish descriptive questions that ask what is present or what happens, comparative questions that examine differences between conditions, and experimental questions that test how changing one factor affects another.

Students also examine how an investigation plan should match its question. The resource addresses choosing suitable tools such as rulers, timers, thermometers, and balances; following approved safety practices; recording observations or measurements; and explaining why a selected method can provide useful evidence.

Science and Engineering in One Resource

The engineering component introduces design criteria as descriptions of what a proposed solution must accomplish. Students consider how a container designed to keep a sample cool can be built, tested, evaluated against criteria, and revised when the evidence shows that the design does not meet its requirements. This connects planning, tools, safety, evidence, testing, and revision across both scientific and engineering contexts.

Student Practice

• Work through multiple-choice questions about investigable questions, descriptive and comparative approaches, tools, safety, methods, and design criteria
• Evaluate true-or-false statements about evidence, investigation planning, comparative approaches, and engineering testing
• Write short responses explaining how observations become questions and why methods must match investigation purposes
• Match related concepts and complete a cloze exercise using scientific investigation and engineering design vocabulary
• Construct an extended response that connects question type, investigation approach, tools, safety practices, planning, testing, evidence, and design revision
• Explore additional context through a Did You Know section

What Teachers Receive

The purchase includes the main Grade 6 Science worksheet, a separate answer key PDF, and a Student Notes & Lesson Summary supplement. The separate Teacher Guide includes Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes for instruction and review.

Use this Grade 6 scientific investigations worksheet for direct instruction, guided practice, independent work, review, or evidence-based writing. The combination of scientific questioning and engineering design gives students a clear context for practicing how questions, methods, tools, safety, criteria, testing, and evidence work together.
