| Define mass | Mass is how much matter something has |
| define volume | volume is how much space something occupies |
| define density | density is a measure of compactness (how much mass is in a curtain amount of space) |
| name the units for mass | grams (g) milligrams (Mg) |
| name the units for volume | litres (L) Millilitres (mL) centimetre cubed (cm3) metre cubed (m3) |
| name the units for density | gram/millilitre (g/mL) gram/centimetre cubed (g/cm3) kilogram/metre cubed (kg/m3) |
| how do you measure mass using a balance | put the substance on an electronic balance |
| how do you measure the volume of an irregular solid with a graduated cylinder? | step 1: measure an amount of water in graduated cylinder (write it down); step 2: drop solid into graduated cylinder and write down the measure and - from the measure before |
| how do you measure the volume of an irregular solid with an over flow can | step 1: fill over flow can up to the spout with water step 2: hold a graduated cylinder under the spout of the over can step 3: then drop the solid into the over flow can and let the water pour into the graduated cylinder and take the measure. |
| how do you measure the volume of a solid | with times length times height use a ruler |
| how do you measure density | mass divided by volume |
| draw the triangle representing mass, volume and density |
