Curated OER
Cosmic Wheels
Students build a scale model of the Solar System and determine the time other planets take to travel around the Sun in comparison to the time of the Earth's revolution. The velocity of the planets are also determined in this lesson.

Was Kepler Correct?
Students are introduced to Kepler's 2nd law of Planetary Motion. The lesson reinforces the understanding of focal points. They calculate the sector area of an ellipse.Students expand understanding by modeling Kepler's 2nd Law of...

Our Solar System
The presentation starts with the scientists who made discoveries about our solar system: Ptolemy, Copernicus, Galileo, Brahe, Kepler, and Newton. It also covers the planets, inner, outer, and Pluto, satellites, and an in-depth discussion...
Curated OER
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...
Curated OER
Black Holes...V
In this black hole worksheet, students read about the black hole in the center of the Milky Way Galaxy called Sagittarius A and observe a Chandra image of the area where the black hole exists. Students solve two problems which include...
Curated OER
Meet the Neighbors: Planets Around Nearby Stars
Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...
Curated OER
Kepler's 3rd Law
Students derive the velocity in a circular orbit of any radius. They derive the Earth escape velocity and prove Kepler's 3rd law for circular orbits # A simple formula for the orbital period in a circular Earth orbit of given radius.
Curated OER
Was Kepler Correct?
Students investigate the elliptical orbit around the Sun. They use the information gathered to measure the distance to the Sun from the closest orbital point and the farthest orbital point.
Curated OER
How Does a Satellite Stay in Orbit?
Students explore placing a satellite into orbit, then about forces needed to keep an object in orbit. They examine how satellites orbit in elliptical paths and about properties of ellipses. They learn Kepler's 3rd Law of Planetary Motion
Curated OER
Kepler's Third Law
Students use Kepler's third law to derive the velocity in a circular orbit of any radius, and identify the Earth escape velocity.

Journey to Mars
Why are there launch windows when traveling to outer space? Scholars explore the trajectory of traveling from one planet to another. By adjusting the departure and destination planets, as well as the launch date, they observe the ideal...
Curated OER
Kepler's Second Law
Pupils explore orbital velocities and how they vary along each orbit, according to Kepler's Second Law.
Curated OER
Kepler's Second Law
Students gain an understanding of Kepler's 2nd law--that planets (and satellites) move fastest at their closest approach to the center of attraction, and slow down when far away. They explore the concepts of "potential energy" and...
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.
Space Awareness
The Engine of Life
There is a specific zone, or distance from a star, that a planet must be in order to have water in a liquid form. The activity demonstrates how flux density depends on its distance from the source. A photovoltaic cell gets power to drive...
Curated OER
Introduction To Orbital Mechanics
Students use NASA drawings to build a model satellite for a specific mission. They design a set of drawings for their satellite showing its subsystems as well.

Astronomy Class
In this space science worksheet, students find the words associated with the basic terms of Astronomy. The answers are located at the bottom of the page.
Curated OER
Solar System
Eighth graders identify the basic concepts of celestial bodies. They discover the difference between perihelion and aphelion and demonstrate how the universe is expanding. They also discover how gravity and centrifugal force are...
