Read the first 7 Inquiry & Project-Based Labs flashcards as text

  1. Which of the following BEST describes 'guided inquiry' compared to 'open inquiry'?

    Answer: The teacher provides the question and procedure while students collect and analyze data

    In guided inquiry, the teacher supplies the question and procedure, but students perform data collection and draw their own conclusions.

  2. A teacher uses a 5E instructional model for a PBL unit on bridges. Which phase involves students constructing and testing their bridge designs?

    Answer: Explore

    The Explore phase is where students conduct hands-on investigations and gather firsthand experience with the concept.

  3. When teaching experimental design, why is it important for students to use a control group?

    Answer: To provide a baseline for comparing the effects of the independent variable

    A control group serves as the baseline, isolating the effect of the independent variable by holding all other conditions constant.

  4. A middle school class is beginning a PBL unit on renewable energy. Which activity BEST activates prior knowledge and sparks inquiry?

    Answer: Watching a teacher demonstration of a solar-powered device and generating questions

    Demonstration combined with student-generated questioning activates schema and creates authentic curiosity, launching inquiry effectively.

  5. Which of the following is an example of a 'fair test' principle that students must apply in lab investigations?

    Answer: Keeping all variables constant except the one being tested

    A fair test requires controlling all variables except the independent variable so that results can be attributed to that variable alone.

  6. A student team's PBL prototype fails during testing. How should the teacher BEST frame this moment?

    Answer: As an opportunity to analyze, iterate, and improve the design

    Failure in PBL is integral to the engineering design process—teams analyze what went wrong and iterate toward a better solution.

  7. What is the PRIMARY reason STEM teachers ask students to share and compare data across lab groups?

    Answer: To build statistical understanding and identify patterns or variability across trials

    Cross-group data sharing builds understanding of variability, sample size, and pattern recognition—key components of scientific reasoning.
