As materials cool, they become more dense causing them to fall--in turn they heat up and it goes in a circular motion.

You have a 400 cm3 sample of water with a mass of 400 grams what is the density?
Water has a density of 1 g/cm3

What are some ways that models of the Earth can be helpful?
We can see the relation of land forms to one another. Using a globe lets us visualize better proportions of lan masses as flat maps have to stretch out parts of the world to be flat on a paper.

What is Archimedes’ principle and explain how it was discovered.
Archimedes used water displacement and buoyancy to find out if the king's crown was made of gold or another metal.

Explain how to determine density.
You find the mass of the object with a balance scale and the volume of the object using LxWxH or water displacement. The formula is Density=mass/volume.

What is the formula for finding density?
D=M/V

Give the average density for each of earth’s layers.
Core:9-13 g/cm3
Mantle: 3 to 9 g/cm3
Crust: 2.7 to 3 g/cm3
atmosphere: Less than .0001 g/cm3

What day is Winter Solstice this year? ....what is that anyway?
December 22. This day has the very shortest amount of daylight hours. We will continue our journey around the Earth and with each day we will gain a few more minutes of sunlight because of how our Earth is tilted.

From what you learned in objective 1, why do you think the layers of the earth are
separated by density?
Materials that are most dense go to the bottom, while less dens materials find their way to the top. So the core is the most dense and the Atmosphere is the least dense.

If you have a 10 cm3 sample of rock salt with mass of 25 grams, what is the density?
The rock salt would have a density of 2.5 g/cm3

Why would a lead fishing weight float in a beaker of liquid mercury?
Mercury has a density that is much more than lead....so the lead weights will float.

Do you have a seriously good moment of science right now?
double points!

Find the density of an unknown liquid in a beaker. The empty beaker's mass is 150 grams. With the unknown liquid inside the beaker, the total mass is 300 grams. The volume of the unknown liquid is 225mL. Is the liquid pure water?
No, the liquid is not pure water because the density is .66 which is less than the density of pure water.

What is the state of matter for each of the layers of the earth? What is unique about the mantle?
Core is solid
Crust is solid
Atmosphere is a gas
The mantle is partially solid and liquid rock called magma

List the main materials found in each of earth’s layers.
Atmosphere: Nitrogen and Oxygen
Crust: Oxygen, Sillicon, Aluminum
Mantle: Magnesium, Sillicon, Oxygen, Iron
Core: Iron, Nickle

Explain why a hot air balloon rises through the air around it?
The hot air is less dense than the cooler air, making the balloon float upwards.

If you place an assortment of various solid objects in a box and shake it back and forth, how would the objects be sorted?
The objects that have a greater density will go to the bottom of the box, while the less dense objects will move to the top.
