In granular matter, complex collective behavior emerges from simple interparticle interactions. By actively agitating a granular material while shearing it, we find a rich rheology: Newtonian behavior at low shear rate and density; a yield stress at high density; and crossing over to Bagnoldian shear thickening when sheared rapidly -- making such out-of-equilibrium material particularly challenging to encompass in one unified theoretical framework. We show that all rheological regimes can be delineated using simple scaling arguments. We link the observed regimes to microscopic parameters by tweaking the contact timescale(s) using electrostatic forces. Finally, by comparing fluidization-induced to Brownian agitation, we propose a constitutive relation that captures all flow behaviors in one unified framework, drawing connections between molecular glasses, Brownian systems, and living systems.
