STEM careers and scientific research take center stage in this Grade 7 Science worksheet, connecting evidence-based investigations with engineering innovation, career preparation, and the people who advance technology. Students explore how scientists and engineers use different methods, collaborate to solve problems, and evaluate the benefits and costs of new solutions while investigating what working in a STEM field involves.

Using Dr. Ellen Ochoa's work developing optical systems as a real-world example, students examine how scientific knowledge and engineering design complement one another. They also consider how people with varied backgrounds, experiences, and skills contribute to scientific and technological progress.

🔬 Investigate evidence, sources, and innovation

The reading passage introduces practical ways to evaluate scientific and engineering claims. Students consider why a source's credibility matters, how evidence and documented methods support a claim, and why comparing information from museums, universities, government agencies, and professional organizations can strengthen an investigation.

Rather than treating every source or innovation as equally reliable or beneficial, learners examine the reasoning behind a claim. They compare research methods, recognize potential limitations, and consider how benefits, costs, resources, testing, and maintenance affect technological decisions.

🧠 Skills students practise

• Evaluate credible sources by examining evidence, methods, and agreement across reliable information.
• Compare research approaches and identify their benefits, limitations, costs, and practical challenges.
• Describe STEM career preparation, including education, training, communication, teamwork, mathematics, science, and problem solving.
• Explain how collaboration and contributions from people with varied backgrounds strengthen scientific and technological work.
• Assess the benefits and costs associated with an innovation or technological solution.

Students apply these ideas through multiple-choice questions, true-or-false statements, concise written answers, matching pairs, a fill-in-the-passage activity, and an extended response. The career investigation prompt asks learners to choose a STEM profession connected to an interest, identify credible sources and relevant evidence, describe required preparation and skills, and evaluate a related technology's benefits and costs. A Did You Know feature adds a further point of interest connected to the lesson.
