Less denseMore dense

Less denseMore dense

Calculating density: Density = mass / volume D= m/v Find density of a ball of aluminum that has volume of 32.4 mL and mass of grams. Find density of a ball of gold that has mass of 38.6 grams and volume of 2 mL. Which is more dense aluminum or gold?

Stratify [strat-uh-fahy] verb : to form or place in layers; to lay in beds or layers

SINK OR FLOAT? What pattern do you see for those objects that are less dense than water and those that have more density than water?

Density is affected by temperature. Water density decreases as temperature increases and vice versa. 15 °C20 °C
