=Summary=

===Students are tasked with answering the question “What can we do to help lower or eliminate the causes/effects of Acid Rain, Air Pollution, Water Pollution and Deforestation?” They form groups in which students take the role of a chemist, economist, biologist, or medical researcher in order to create a project that will answer some facet of this question with mathematical support from each field of study represented by the group. ===

=CCSS Alignment for Grades 6-9=


 * ===**6.RP.1 **. //Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.// Students will use ratio language to explain the relationship between deforestation, for example, and CO2 levels in the earth’s atmosphere. ===
 * ===**7.RP.3 **. //Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.// Students will express proportional relationship between air pollution and acid rain, for example, in terms of percent increase or decrease. ===
 * ===**8.SP.4. ** //Understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table. Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects. Use relative frequencies calculated for rows or columns to describe possible association between the two variables.// Students will investigate patterns of association between air and water pollution in specific geographic locations using relative frequencies to describe possible association. ===
 * ===**S-IC.5 **. //Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.// Use water treatment data, for example, from two different sites to decide if water pollution shows significant change between locations. ===
