Figures

Image of Fig. 1.
Fig. 1.

A schematic Hubble plot for a universe with a constant Hubble parameter.

Image of Fig. 2.
Fig. 2.

The first question of the “Hubble’s Law” Lecture-Tutorial.

Image of Fig. 3.
Fig. 3.

A graphing activity that requires students to reason about how to construct Hubble plots while taking into account the observers location and how the recessional velocities of galaxies are relative to their distance from the observer.

Image of Fig. 4.
Fig. 4.

A sample Ranking Task.

Image of Fig. 5.
Fig. 5.

A question, which may be used as a Think-Pair-Share activity, that makes students reason about the meaning of negative quantities on Hubble plots.

Image of Fig. 6.
Fig. 6.

A schematic Hubble plot for a universe with a Hubble parameter that changes with time.

Image of Fig. 7.
Fig. 7.

A series of questions from the “Hubble’s Law” Lecture-Tutorial on the accelerating expansion of the universe.

Image of Fig. 8.
Fig. 8.

The questions from the first page of the “Dark Matter” Lecture-Tutorial. These questions help students to understand why the Solar System’s rotation curve is Keplerian.

Image of Fig. 9.
Fig. 9.

A sample of questions from a single page of the “Dark Matter” Lecture-Tutorial. These questions help students to understand why a spiral galaxy’s rotation curve implies the existence of an unseen mass component.
