Heavy for its size?
Mass alone does not tell you density.
Take your time. Speak, draw or write your answers.
Here is what is happening.
Density is mass divided by volume. Units must be consistent: grams per cubic centimetre, for example. Two objects with equal mass can have different densities if their volumes differ. For a uniform object in a liquid, comparing their densities helps predict floating or sinking.
Pause. Make the idea your own.
Explain one idea to a partner, draw it or write it in your own words. Which part is an observation, an example or a question?
You can use a home language. No need to share personal experiences or finish everything in one sitting.Your little investigation
What you need
Paper and a calculator if you wish. Use the given imaginary measurements.
Object A: mass 60 g, volume 20 cm³. Object B: mass 60 g, volume 30 cm³.
Calculate each density and include units.
Explain why the equal masses do not imply equal densities.
What is A’s density?
