QOD #15 (on paper)  Mr. Walker has a mass of 75 kg on Earth. What would his mass be on the moon? What would his mass be on Mars?

QOD #16 Items that sinkItems that float Draw and fill in the table. Try to list 5 of each.

Density – the amount of matter in a given space, or volume. Brick & Sponge  The brick has more mass than the sponge.  Brick has a greater density. Density Notes

D=density M=mass V=volume D = M V D = Units for density:  g/cm  g/mL  kg/m  kg/L

Example: What is the density of an object whose mass is 25 g and whose volume is 10 cm 3 ? D = M V D = 25 g 10 cm D = 2.5 g/cm

Practice 1. Find the density. M = 10 g V = 2 mL D = 10 g / 2 mL D = 5 g/mL 2. Find the density. M = 600 g V = 50 cm D = 600 g / 50 cm D = 12 g/cm

Sink or Float??

Why did the objects sink?  The objects sank because they are more dense than the water.

What will happen if I pour corn oil into a graduated cylinder of water? Hypothesis: If I pour corn oil into a graduated cylinder of water, then ….. because …..

Diagram: Conclusion:  When I poured the corn oil on the water …  Objects and liquids that are more dense sink.  Objects and liquids that are less dense float or rise.
