## Hassan's Pictures - Linear Programming and Profit Lines

Find the feasible region in a linear programming problem, graph a family of profit lines and find the optimum point.

## Hot Dog Sales - Solving Linear Equations and Inequalities

Provides an introduction to solving equations and inequalities numerically (using a table), graphically, and algebraically.

## Latin America - Mexico: Motive to Migrate

Consider the several push-pull factors involved in the migration of Mexican workers to the Maquiladoras of Monterrey, and to the U.S. for seasonal work, then back home to north central Mexico.

## Left Hand, Right Hand - Solving Systems of Equations

Compare the speed at which you write with your left hand to the speed at which you write with your right hand In order to understand the three different types of possible solutions to a system of two equations with two unknowns.

## Life Cycles (Session 3)

Observe adult, larvae (mealworms), and pupae of the darkling beetle. Monitor over the next several days and determine the life cycle.

## Life's Not Fair

Read two books on the same theme, record questions and responses and meet with others reading the same book.

## Mathematical Modeling, Circular Movement and Transmission Ratios

Examine the difference in the number of revolutions for each of two gears in a model, in order to undertand the significance of the radii of the gears.

## Melting Point of Ice

Take readings of a thermometer in a glass of ice and then in warm water. Watch the volume of the red liquid in the thermometer expand, to develop ideas about the effect of energy on the change of state of matter.

## Miles of Tiles - The Pool Border Problem

Algebraic notation and variables are used to recognize patterns and represent situations.

## Moon's Distance from Earth

Work with models to represent the relative distance of the Moon from the Earth, then measure the angular size of the Moon with pinky fingers to check the estimate.

## North Africa / Southwest Asia - How a Country's Boundaries Are Shaped

Examine the past and present boundaries of Jerusalem and the reasons why and how these came about.

## North Africa / Southwest Asia - The Gift of the Nile: Egypt and Its River

Examine how human interaction with the environment has altered the annual flooding of the Nile River and what the implications are for the region.

## Overrun by Skeeters - Exponential Growth

This introduction to exponential functions considers the world population since 1650. In a simulation, the population grows at a random yet predictable rate.

## Persuasive Writing

Use discussions of rap music to encourage the class to develop and articulate their opinions in persuasive writing pieces.

## The Phone Bill Problem - Linear Functions

Write an equation of a linear function when given a set of data. Interpret the meaning of the slope and y-intercept and then use the equation to find other values of x and y.

## Plate Tectonics

Use interactive, computer-based inquiry to create models of plate interactions and record explanations of the models.

The class works on individual goals, preparing literature log entries in writer's notebooks and developing a literary poster and a presentation based on a novel.

## Rocks

Examine rocks that contain fossils, observe their characteristics and research to find out what kind of rock it is.

## Russia - Capitalizing on Geography

Why are cities located where they are? What geographical information can explain the location of Russian cities?

## Skeeter Populations and Exponential Growth

Exponential functions are used to represent population growth.
