Mass Reading draws a triple beam balance or a digital balance showing the mass you type. On the triple beam balance the three riders are placed for that mass, and students add up the 100 g, 10 g and 0–10 g beams, reading to 0.01 g. A digital balance shows the mass to 1, 2, 3 or 4 decimal places; at 3 or 4 places it is drawn as an analytical balance inside a draft shield.
Put a weigh boat or a beaker on the digital balance’s pan, or one of the objects from Volume by Displacement (marbles, a rock, a cube or a metal cylinder) on either balance, so a mass figure and a volume figure together make a density question. The answer key prints the reading 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.
Add the positions of the three riders: one on a beam marked in 100 g steps, one on a beam marked in 10 g steps, and one that slides along a beam marked every 0.1 g from 0 to 10 g. Estimate one more digit on that last beam, so a reading looks like 347.26 g.
A balance that reads to 0.001 g or 0.0001 g is an analytical balance, which sits inside a glass draft shield so air currents don’t disturb the reading. The generator draws one when you pick 3 or 4 decimal places.
No. A digital balance’s reading is exactly what its display shows, so students copy every digit, including trailing zeros. On the triple beam balance the last digit is estimated.
Yes. Pick the same marbles, rock, cube or metal cylinder under On the pan. It is drawn alike in both generators, so students can find its mass here and its volume in Volume by Displacement, then work out its density.
