Curated OER
The Celestial Sphere
Pupils are introduced to the celestial sphere, describing its apparent rotation and the special role of the pole star.
Curated OER
Seasons of the Year
Students examine how the link between the tilt of the Earth's axis to the ecliptic and seasons of the year--length of day, effectiveness of sunlight, polar day and night, and seasons south and north of the equator, as well as near it.
Curated OER
Newton's 3rd Law
Students examine how the formal definition of Newton's 3rd law: forces always originate in pairs, equal in magnitude and opposite in direction. They also examine how the informal, qualitative version: Each action has an equal and...
Curated OER
Motion in a Circle
Students explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T. They examine how uniform circular motion is a type of accelerated motion.
Curated OER
Frames of Reference: The Basics
Learners learn the concept of frames of reference in physics. They examine how two frames of reference, each moving with respect to the other with a constant velocity v (constant speed, constant direction).
Curated OER
Airplane flight
Students learn the basic concepts about airplane flight. They learn the reason jetliner wings are swept back and why jet engines have replaced propellers in high-speed flight.
Curated OER
#22 Frames of Reference: The Basics
Pupils explore the concept of frames of reference in physics.
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
Graphs And Ellipses
Learners become acquainted with linear graphs, the parabola and the rectangular hyperbola. Also prepare tables of paired values as preparation for plotting a line. They study the cartesian equation of an ellipse, with a worked example.
Curated OER
The Mystery Constellation
Students decipher two teacher chosen mystery constellations a month. They listen to stories, explain what they know about constellations and name the mystery constellation.
Curated OER
Eyes on the Sky, Feet on the Ground
Fifth graders participate in online astronomy activities with hundreds of fun explorations into astronomy as a classroom tool for learning how to theorize, experiment, and analyze data.
