Geography, the word created by Eratosthenes, generally means to write about the Earth. Geography is divided amongst human and physical aspects. Human geography studies where and why human activities occur where they are. Physical geography studies where and why natural occurrences happen where they do. The book concentrates on two main topics- culture and economy. The first key issue in the first chapter is geography?s most important tool-mapping. A map is a two dimensional model of a part of the Earth or the whole Earth. During the first chapter the basic concepts of ?why? questions were introduced. Geographers study to find why each place on earth has their own unique ways.

CAMPBELL BIOLOGY, AP* 9th EDITION Chapter 26: Phylogeny and the Tree of Life Biologists trace phylogeny - evolutionary history of a species or group of species To construct phylogenies, biologists use systematics - a discipline focused on classifying organisms and determining their evolutionary relationships. 26.1 The scientific discipline of taxonomy is how organisms are named and classified Common names don?t necessarily reflect the organism they signify (ex: silverfish is a bug and jellyfish is a cnidarian). So, we use Latin scientific names. They come in binomial, or two-part, format. Part 1 - the genus (pl. genera) of the organism Part 2 - ?specific epithet?, which is unique for every species in the genus.

The Unit 7 Test Review The test will consist of 25 multiple choice questions. Scantron answer documents will be used. You will need a #2 pencil and a calculator. A periodic table will be provided. In order to be successful with this test you need to know your diatomics and polyatomic ions. Be sure you can write formulas and balance ionic charges. Please study your notes, quizzes, and practice worksheets. Be sure to complete the WebAssign. Name a hydrate Write the formula for a hydrate Calculate the percent by mass of water in a hydrate using a given formula Calculate the percent by mass of water in a hydrate using lab data Determine the formula of a hydrate using lab data (similar to the hydrate lab) Differentiate between basic state of matter symbols: (s), (l), (g), (aq)

2: Thinking Like an Economist Intro economics can be thought of as a science scientific method: ? the dispassionate development and testing of theories about how the world works: The Economist as Scientist The Scientific Method: Observation, Theory, and More Observation economist can observe whats going on around him, then make theories based on that will collect data from all over to test his theory harder for economists to make experiments, have to just use whats given to them rely strongly on examples in history The Role of Assumptions assumptions can simplify complex ideas and make them easier to understand or give you a better idea of the complex idea different assumptions for different situations short term =prices stay the same long term= prices are flexible

Ecology-A Study of Relationships Ecology means the study of the home Ecology is the study of organisms in their natural environment Biosphere is everywhere that life exists Viewing planet Earth from Space Satellites are an economical way to gather data; they have sensors, these gather data quickly from a very large region, and they last a long time Electromagnetic radiation Total ozone-mapping spectrometer Understanding environmental interactions allows us to predict the effects of human activity Biomes- Climatic Zones of Life Biome- a large geographic region determined by the climate and soil type Climate- average weather pattern over a long period of time Ecosystem- a Functional Unit Ecosystem is the Functional Unit because biome is too big to conduct research
