Ellipses and Kepler's First Law
The class examines graphs in the form r = F(¿¿) in polar coordinates (r, ¿¿), in particular with the circle, ellipse and other conic sections. They determine the nature of an ellipse by studying the role of the semimajor axis and...

Earth Science Regents: The Ellipse
Starting with the instructions to draw an ellipse, and with great pictures, this sheet should help your pupils learn the shapes and measurements involved. Using push pins and string, your class can discover the axis and focus points...

Drawing Ellipses Lab
In this ellipse worksheet, students learn the difference between an orbit and an ellipse. They draw ellipses and calculate the distance between foci, they calculate the length of the major axis and they determine the eccentricity. They...

Ellipses
In this ellipses worksheet, students calculate the eccentricity of 5 given ellipses and show their calculations. Students then determine the percent deviation for their calculations using the accepted values of eccentricity.

Kepler’s Laws
Introduce your physics or astronomy class to Kepler's laws of planetary motion with this straightforward worksheet. It covers the basic concepts of each and has learners answer questions to demonstrate their grasp on them. You could use...
Curated OER
Ellipses
In this ellipses activity, students measure and calculate the eccentricity of each ellipse and then calculate the percent deviation. This activity has 10 problems to solve.
Curated OER
Planetary Orbit
Students compare and contrast ellipses of various eccentricities that represent the shape of planetary orbits. They make a circle with the string by trying the two ends togther. Students calculate the eccentricity of their ellipses by...
Curated OER
Ellipses And Kepler's First Law
Students explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

Orbital Motion
Why do planets orbit the sun in ellipses when moons orbit their planet in circles? Pupils control the semi-major axis, eccentricity of the orbit, and position angle. The resulting orbital appears with the related force vectors as...

Planet Paths: Studying Planetary Orbital Paths
Students define and identify planetary orbit, ellipse, parabola, and hyperbola, and simulate Kepler's Second Law. They explore interactive websites demonstrating orbital motion and complete modeling activities.

Orbital Motion
Young scholars use a formula to measure the eccentricity of an ellipse, then state Kepler's Law of Elliptical Orbits. They predict the solar energy received at different positions in a planet's orbit.

Orbits Worksheet #1
A diagram of Earth's path around the sun, including the position of the moon, is displayed at the top of the worksheet. Five multiple questions get astronomers to analyze the diagram considering what is going on in the solar system. Use...
