Marshmallow Muscles Larry 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. Warm-up Monday, August 26 Which person is in the control group? What is the dependent variable? What should Larry’s conclusion be? SpongeBob – regular lotion Muscle Power It seemed to worked

Minerals “All minerals are rocks but are all rocks minerals?” ** If it’s written in yellow, write it down. **
Of the almost 4000 known minerals, only about 30 are common. The most common are quartz, feldspar, mica, and calcite.
These minerals make up most of the rocks found in the Earth’s crust.
A mineral is • Naturally occurring (not made by man) • Solid • Inorganic (never alive) • Specific chemical composition • Crystalline shape (repeating pattern of atoms.
Minerals 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. Naturally Occurring
Inorganic materials were never living. Coal is made from the remains of ancient plants and animals, so coal is not a mineral. Inorganic
Definite shape, definite volume. The state of matter when the material is below its freezing point. Particles are fixed in place. Solid
The particles of the materialline up in aregular, repeating pattern. Has flat sides called faces, that meet at sharp edges and corners. Crystal Structure
FORMATION • Mineral are formed: • When magma cools • Cools Slowly = LARGER crystals • Cools Quickly = smaller crystals • When a mineral is dissolved in a liquid • Liquid evaporates Slowly = LARGER crystals Quickly = smaller crystals
Always 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. Definite Chemical Composition
Quartz SiO2 Silicon + 2 Oxygen
Halite Cubic Crystal System NaCl Sodium Chloride
Amethyst SiO2 Iron or manganese impurities Hexagonal
Divided into two groups based on mineral composition. Silicate minerals Non-silicate minerals Two Groups of Minerals
Made of silicon and oxygen, the most common elements in the Earths crust (90%) Quartz Feldspar Mica Silicate Minerals
Non-silicate Minerals • Contains carbon, oxygen, fluorine, and sulfur.
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?
Color • Impurities can cause a mineral to come in a variety of colors • Least reliable way to identify a mineral
