39  Module 8: From the Universe to the Atom

39.1 Overview

From the Universe to the Atom links cosmic evidence to atomic and subatomic physics, explaining how matter and energy interact at the smallest scales.

39.2 Inquiry questions

• What evidence is there for the origins of the elements?
• How is energy produced in stars?
• How do the properties of the nucleus give rise to the properties of matter?
• What are the implications of mass defect and binding energy for nuclei?

39.3 Outcomes (syllabus wording)

• PH11/12-5 analyses and evaluates primary and secondary data and information.
• PH11/12-6 solves scientific problems using primary and secondary data, critical thinking skills and scientific processes.
