For phetsims/qa#1136

For Buoyancy Basics under Reorder the materials in the ComboBox change
buoyancyBasics.exploreScreen.view.fluidDensityPanel.comboBox.listBox

to
buoyancyBasics.exploreScreen.view.fluidPanel.comboBox.listBox

Any further changes/suggestions will also be added to this issue.

For Density, since the Volume Units are the only thing in the Simulation Tab of the Preferences Menu I would suggest changing the visible property of the the tab rather than the visible property of the volumeUnits Control.

Change:
density.general.view.navigationBar.preferencesButton.preferencesDialogCapsule.preferencesDialog.preferencesPanels.simulationPreferencesPanel.volumeUnitsControl.visibleProperty

To:
density.general.view.navigationBar.preferencesButton.preferencesDialogCapsule.preferencesDialog.preferencesTabs.simulationTab.visibleProperty

• Please note that we should update some doc here about how "custom" materials works as a mode instead of a value, block material combo box says "custom" no matter which option is chosen [BASICS] #362 (comment)

Thanks @Nancy-Salpepi! I made the suggested changes in the above commits.

To address #371 (comment), I added this to the Density and Buoyancy under the 'Specify block density' section:

The Custom material behaves differently, allowing independent control of mass and volume. Its densityProperty is not a constant, and can be changed by subsequent interaction with the mass, volume, or material controls. For this reason, we recommend you first set the material to ‘Custom’ before modifying its density.

I did not add this information to Buoyancy: Basics, because customMaterial.densityProperty behaves a bit differently since it is tied to the Density slider.

Closing!
