1. DENSITY is the MASS (or weight) / volume (the amount of stuff).  When a substance is heavy for its size, it has greater density.
2. Oil will float on water; oil is less dense than water
3. Fresh water is less dense than salt water; fresh water will float on salt water; water will become more dense, the more salt is added
4. A helium balloon will rise/float because the helium air is less dense than the atmosphere/air
5. Density = Mass / Volume
6. Density can be used to identify substances.  A small piece of gold and a large piece of gold will have the SAME density.
7. Temperature is the measurement of how hot or cold something is.
8. Temperature is usually measured in Celsius in science.
9. Minerals are naturally occurring, inorganic solid with a definite composition and atoms arranged in a repeating pattern.
10. Rocks are made up of a variety of elements and minerals.
11. Properties used to identify minerals are: color, luster, streak, fracture, hardness, and specific gravity.
LUSTER
FRACTURE/CLEAVAGE
12. Birthstones are minerals.
13. There are three main categories of rocks: igneous, sedimentary, and metamorphic.
14. IGNEOUS rocks are formed from the cooling and hardening of magma or lava.
15. MAGMA is molten material inside the earth.
16. Lava is molten material outside on the surface of the earth.
17. Igneous rocks can be classified into two major types: intrusive or extrusive.
18. Intrusive igneous rocks have larger crystals and are formed underground.  Granite is an example.
19. Extrusive igneous rocks have small or no visible crystals and are formed on the surface of the earth.  Pumice, obsidian, and basalt are examples.
20. SEDIMENTARY rocks are rocks formed from sediments (loose materials such as pieces of rock, gravel, sand, silt, clay, mineral grains or the remains of plants and animals) that are compacted and/or cemented together.
21. Sedimentary rocks can be classified into three major types: detrital, chemical, and organic.
22. Detrital sedimentary rocks are rocks that have sediments such as conglomerate, breccia, sandstone, or shale.
23. Chemical sedimentary rocks are rocks that form from evaporation or precipitation such as halite (rock salt).
24. Organic sedimentary rocks are rocks that form from the remains of plants or animals such as limestone or coal.
25. METAMORPHIC rocks are formed when heat (to make or become hot) and pressure change the composition of rocks so that they partially melt and the minerals rearrange into parallel wavy layers or have mineral grains that change or grow to appear deformed.
26.  There are two basic types of metamorphic rocks, foliated and nonfoliated.  Examples of metamorphic rocks are slate, schist, gneiss (NICE), marble and quartize.
27. The ROCK CYCLE is a continuous cycle of forming and changing rock from one rock type to another using processes such as, weathering and erosion, heat and pressure or complete melting of rock material.
28. FOSSILS are the remains of plants or animals that have been preserved over time.  Fossils are preserved where conditions for decomposition are poor; the plant or animal is protected from scavengers and microorganisms, in a place that has very little moisture, oxygen or warmth.
29.  The necessary conditions so that plants and animals might be fossilized are: trapped in sap/amber, ice or tar; dried in sand, at the bottom of a lake or sea, covered in volcanic ash
30. Here is the type of fossilization that can occur: molds, casts, imprints, petrified, original remains, carbonaceous film, and trace.
31. The earth is made up of three main layers: CRUST, MANTLE, and CORE.  The crust is the outermost layer and is very thin in comparison to the rest of the planet.  The crust is anywhere from 5 - 35 km deep.  The oceanic crust is the thinnest part of the crust.  The mantle is middle layer.  The core is the center layer.  The core is composed of iron and nickel.  The inner core is solid and the outer core is liquid.
32. PLATE TECTONICS is the theory that Earth's crust is broken up into sections, called plates, that slowly move over the mantle
33. CONVECTION is the transfer of heat by a flow of heated material; occurs in gases or liquids (Examples are: boiling water, lava lamp, cream in coffee, etc.)
34. HEAT does NOT rise, but hot gases or liquids DO rise!  Remember that if you touch the bottom of a pan or pot, you will get burned (because heat does not rise)!  If you still believe that heat rises, then try it for yourself (Just kidding, do not try this at home!).
