Marshmallow MusclesLarry was told that a certain muscle cream was the newest, best thing on the market and claims to double a person’s muscle power when used as part of a muscle-building workout. Interested in this product, he buys the special muscle cream and recruits Patrick and SpongeBob to help him with an experiment. Larry develops a special marshmallow weight-lifting program for Patrick and SpongeBob. He meets with them once every day for a period of 2 weeks and keeps track of their results. Before each session Patrick’s arms and back are lathered in the muscle cream, while Sponge Bob’s arms and back are lathered with the regular lotion.
Which person is in the control group? What is the dependent variable? What should Larry’s conclusion be?
SpongeBob – regular lotion

Minerals“All minerals are rocks but are all rocks minerals?”** If it’s written in yellow, write it down. **Slide6
Of the almost 4000 known minerals, only about 30 are common.The most common are quartz, feldspar, mica, and calcite.Slide7
These minerals make up most of the rocks found in the Earth’s crust.Slide8
A mineral isNaturally occurring (not made by man)SolidInorganic (never alive) Specific chemical compositionCrystalline shape
(repeating pattern of atoms. Slide9
Naturally OccurringMinerals must occur naturally.Cannot be man made.Cement, bricks, steel, and glass all come from materials found in the earth, but these are made by people.Slide10
InorganicInorganic materials were never living.Coal is made from the remains of ancient plants and animals, so coal is not a mineral.Slide11
SolidDefinite shape, definite volume. The state of matter when the material is below its freezing point.Particles are fixed in place.Slide12
Crystal StructureThe particles of the material line up in a regular, repeating pattern.Has flat sides called faces, that meet at sharp edges and corners.Slide13
FORMATIONMineral are formed:When magma coolsCools Slowly = LARGER crystalsCools Quickly = smaller
crystalsWhen a mineral is dissolved in a liquidLiquid evaporates Slowly = LARGER crystals
Quickly = smaller crystalsSlide14
Definite Chemical CompositionAlways contains certain elements in the same proportion.Almost all minerals are compounds, which are two or more different elements bonded together (holding hands).Pyrite is two sulfur atoms holding hands with an atom of iron.Slide15

Non-silicate MineralsContains carbon, oxygen, fluorine, and sulfur.Slide21
Closing:Ticket Out the Door(TOD)Without talking, find two people who have the same birth month as you. Write their names down.What is your birthstone?Slide22Slide23Slide24
