Density Lab

Investigate mass, volume displacement, density, and buoyancy.

Graduated beaker Digital scale Fluid level: 150 mL 0.0 g GOLD Drag object to scale (S) → ← or beaker (B)
Scale mass0.0 g
Fluid reading150 mL
Liquid density1.00 g/mL
Object stateOut of liquid
Instructions: Move the block onto the scale to measure its mass, or into the beaker to observe the change in fluid level. Compare the reading to the initial 150 mL level. A floating object displaces fluid with a mass equal to its own mass; a fully submerged object displaces its entire volume. Try different materials and liquid densities.

Keyboard shortcuts: S = Scale   |   B = Beaker   |   H = Hold under (Submerge)   |   T = Table   |   R = Reset Experiment

The mystery object's density is hidden. The beaker uses an idealized, constant-area volume scale; values are rounded for display.
