Volume by Displacement draws the same graduated cylinder twice, side by side: before and after an object is dropped in. You type the before and after readings, and students read both and subtract to find the displaced volume, which is the object’s volume.
It suits density units and irregular-solid labs. Mass Reading can put the same marbles, rock, cube or metal cylinder on a balance, so a pair of figures gives students the mass and the volume they need to work out density. Turn on the answer key to print both readings and the object’s volume under the figure.
Copy the figure straight into a test, worksheet or slide, or download it as a PNG or SVG. Printing the page prints just the figure. Share link copies the page’s address with your settings in it, so anyone who opens it sees this exact figure, and presets save settings you use often in your browser. It’s free, with no sign-up.
Read the water level before the object goes in, then after. The after reading minus the before reading is the displaced volume, which equals the object’s volume. For example, 32.0 mL before and 38.5 mL after gives 6.5 mL, or 6.5 cm³.
No. It is drawn at a plausible size rather than exactly to its volume, always resting on the bottom and fully under water. If there is too little water to cover it, it is drawn smaller; raising the readings fixes that.
Yes. Make the displacement figure, then open Mass Reading and put the same object on a balance; it is drawn alike in both. Students find the volume from one figure and the mass from the other, then divide mass by volume.
Yes. Under Scale, pick finer or coarser marks, number them more or less often or not at all, and choose mL or cm³. Both cylinders and the answer key follow.
A displacement question needs the smaller cylinders, so this generator offers 10, 25, 50 and 100 mL. Volume Reading has the 250 and 1000 mL cylinders for a single reading.
