Bridges+Unit

Bridges

Bridges have been used throughout history as a link from one place to another. To get a better understanding of leaders, world powers, and geographical challenges that have plagued cities and countries throughout the world we are going use bridges to create a link. In this unit students will be working collaboratively with groups to study a famous bridge and the history, engineering, and usage behind it. Along with the research of the bridge students will be using skills recently covered in math on ratio and proportion to create a 2-D scale model of their selected bridge.

Day 1: Getting to know the unit activity Students will be split into groups to start to discover the many uses, types, and importance of bridges throughout the world. Stations: >> Bridges Group Rubric
 * 1) Types of Bridges:
 * Read and discuss the provided article on the different types of bridges.
 * The different bridges we will be looking at are:
 * Beam Bridges
 * Truss Bridges
 * Arch Bridges
 * Suspension Bridges
 * Cantilever Bridges
 * When you have finished looking at the diagram and reading about the different types of bridges please look at the discussion questions at your station and talk with your group about your findings.

 * Describe how buildings and their decoration reflect cultural values and ideas, providing examples such as cave paintings, pyramids, sacred cities, castles, and cathedrals.
 * Analyze information generated from a computer about a place, including statistical sources, aerial and satellite images, and three-dime
 * Identify and examine various sources of information that are used for constructing an understanding of the past, such as artifacts, documents, letters, diaries, maps, textbooks, photos, paintings, architecture, oral presentations, graphs, and charts.
 * Use a timeline to select, organize, and sequence information describing eras in history. Give examples of important contributions made by Wisconsin citizens, United States citizens, and world citizens.

Language Arts Standards:

> Introduce a topic; organize ideas, concepts, and information, using strategies such as definition, classification, comparison/contrast, and cause/effect; include formatting (e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension. > Use appropriate transitions to clarify the relationships among ideas and concepts. > Use precise language > > and domain-specific vocabulary to inform about or explain the topic. Establish and maintain a formal style. > Provide a concluding statement or section that follows from the information or explanation presented.Conduct short research projects to answer a question, drawing on several sources and refocusing the inquiry when appropriate. > Gather relevant information from multiple print and digital sources; assess the credibility of each source; and quote or paraphrase the data and conclusions of others while avoiding plagiarism and providing basic bibliographic information for sources.
 * Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information through the selection, organization, and analysis of relevant content.
 * Develop the topic with relevant facts, definitions, concrete details, quotations, or other information and examples.
 * Draw evidence from literary or informational texts to support analysis, reflection, and research.

Math standards:

> rcent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
 * Understand ratio concepts and use ratio reasoning to solve problems.
 * Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
 * Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship.
 * Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
 * Make tables of equivalent ratios relating quantities with whole number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
