Algebra I

Students will examine data about garbage production and graphically represent it in a scatter plot. Students will use the data to make predictions of future trends. They will also develop an understanding of the environmental impact of trash accumulation and the need for a plan to deal with potential garbage problems. The activity is written for use with a graphing calculator.

Fractals are found extensively in nature, from tiny snowflakes to towering mountains. Because of this, fractal geometry has many practical applications. Geologists can model the meandering paths of rivers. Botanists can model the branching patterns of trees. In this activity, students will investigate fractals, learn how fractals can be used to determine the length of a coastline and explore the expression of mathematical principles in art.
