Calculator

Displacement & Density Calculator

For Activity #005 after you predict, measure, calculate by hand, and test.

Water Level Measurements

Use mL.
Use mL after the object is fully submerged.
Use grams. Leave blank if you only want volume.
How is this calculated?

Final water level - initial water level = displaced water = object volume. In this activity, 1 mL = 1 cm³.

If mass is entered, density = mass ÷ volume.

Float or sink note

Water has a density of about 1 g/cm³. Objects with density below 1 g/cm³ often float, and objects above 1 g/cm³ often sink. Real tests can be affected by trapped air, shape, absorbent materials, and partial submersion.

Learning reminder

Use this calculator after the hands-on work. Prediction, careful measurement, hand calculation, and testing are the main activity.
