- Should not be used.
Summary
Summarize your evidence and reasoning: The task starts with the phenomenon of vastly different melting points for common substances. Students use the flythrough simulation to visualize atomic-level structures and forces. They then apply this understanding to plan an investigation (SEP), inferring atomic electrical forces (DCI: PS1.A) based on macroscopic patterns in bulk properties (CCC). The task is well-integrated and avoids rote memorization.
