STEM Inquiry & Project-Based Labs 3

Question 1

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

Accepted Answer

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

Answer

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

Question 2

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

Accepted Answer

Explore

Answer

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

Question 3

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

Accepted Answer

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

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

Keeping all variables constant except the one being tested

Answer

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