Kepler’s First Law of Planetary Motion

Kepler’s First Law of Planetary Motion

Mr. Steve Heck

Milford Junior High School

8th Grade Earth Science

This lesson is designed to engage students to inquire and discover the principles of Kepler's First Law of Planetary Motion.

At the completion of the lesson, students will present their visual concept of what Kepler's First Law is and how it describes the orbits of all the planets (especially Earth) in an elliptical orbit and not circular orbits around the Sun

Project Overview

Kepler’s First LAW of Planetary Motion Planets move in ellipses with the Sun at one focus.

Kepler’s First LAW of Planetary Motion Planets move in ellipses with the Sun at one focus.

The Visual Concept must include but is not limited to:(1) Title(2) KEY components of Kepler's Law(3) An example of an Elliptical orbit(4) Calculations on how the orbit was made(5) Some form of animation(6) Reference

Kepler•First to explain planetary motion in modern terms (universal, verifiable, and precise).

•Helped start what is known as the ”Scientific Revolution”

•Explained that Planets follow an elliptical pattern

•Tied both science and math together to define Laws of Nature

•Became the basis of Newton’s Laws

 Define the following terms:

Circle: a closed plane curve consisting of all points at a given distance from a point within it called the center

 

Ellipse: a figure drawn around two points called the foci such that the distance from one focus to any point on the figure back to the other focus equals a constant

 

Label the following diagram:

A: Focus or Foci B: Semimajor Axis

C: Semiminor Axis

    Calculations: Eccentricity of an Ellipse

Eccentricity = distance between foci

length of major axis
