1. $6.99 ## The Archer Fish, Geometry, and Physics The Archer Fish earns its name because it accurately sprays jets of water at insect prey, knocks them into the water, and has a quick meal. The ability to accurately do this has to overcome several geometric and physical challenges. In this module students explore these challenges in more detail. In fact there are three mathematical physics challenges that are explored: • Using they Pythagorean Theorem to find the distance the Archer Fish needs to spray its jet of water • Using the Tangent Ratios and their inverses to find the angle of the spray of water • Taking refraction into account by using Snell's Law #### Math Concepts • Problem Solving • Geometry • Equations • Algebra #### Learning Objectives • Use the Pythagorean Theorem to calculate the hypotenuse • Calculate tangent ratios and their inverses • Solve equations with trigonometric functions and their inverses #### Prerequisite Skills • Knows the basics of right triangles • Knows the basics of ratios • Understands what the inverse of a function is Common Core Standards CCSS.MATH.CONTENT.HSG.SRT.C.6, CCSS.MATH.CONTENT.HSG.SRT.C.8 20 mins 9th - 11th Grade #### Lesson Preview 2.$6.99

In this module explore the paths of fireworks and learn about quadratic functions. Students explore parabolas graphed in Quadrant I, with roots at the origin and positive x. Students will learn about quadratic function in:

• Standard form
• Vertex form
• Factored form

In fact, students learn to use parabolas to model specific fireworks trajectories, and therefore solve for the specific parameters for those functions. Try this module for fun and engaging way to learn about quadratics.

## Why Do Rivers Meander?

Rivers twist and turn as they make their way to the sea. Why does this happen and how can this be explained mathematically? In this module we look at the geometry of meandering rivers. In the process we'll discover some fascinating numerical relationships.

Students will learn some basic concepts about the geophysics of how rivers form, but they will focus their analysis on what is called the sinuousity ratio. This is the ratio of the straight-line distance of the river and its meandering distance. This ratio reveals important characteristics of the river. Then, students will develop and examine geometric models involving circular arcs and segments to get a better understanding of the ratio. These models will first involve using a compass and straight edge to model a river. This is followed by an algebraic analysis.

This module is an excellent way of tying real world concepts to geometry and algebra. The real-world application is easy to understand and yet it reveals a wealth of math concepts to be explored.

#### Math Concepts

• Ratios and Rates
• Geometry
• Geometric Constructions

#### Learning Objectives

• Define the sinuousity of a river
• Calculate the ratio the defines the sinuousity of a river

#### Prerequisite Skills

• Basic understanding of circles
• Basic understanding of ratios
• Some familiarity with the Pythagorean theorem
