Curated OER
That Mu You Do
Learners are told that the weight of a car is equal to its mass multiplied by the acceleration due to gravity. When a car is at react on a horizontal road, there must be a normal force with which the road pushes up on the car to keep it...

Quadratics: Polynomial Form
Students determine how changes in the coefficients in a quadratic function affect its graph. They Solve a quadratic equations. Students Determine how to use the equation to determine the intercepts of a quadratic function. They...

The Corner Problem
Students explore the concept of the corner problem. In this corner problem lesson, students use the TI-NSpire to determine the maximum length a rod can be and still pass horizontally around a corner. Students use similar triangles to...
Curated OER
Parallax
High schoolers discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."
Curated OER
How Distant is the Moon?--2
Pupils examine total eclipses of the Sun and their limited regions of totality. They explain that this limited view occurs because the Moon is close enough to us for different points on Earth to view it differently.

May The Earth Be Revolving Around The Sun?
Students trace the beginning of the heliocentric theory of the solar system--the idea that the solar system revolves around the Sun--to an observation by the Greek astronomer Aristarchus, which convinced him that the Sun was much bigger...
Curated OER
May Earth be Revolving around the Sun?
Ninth graders explore how Aristarchus used the position of the half-full Moon to estimate the distance to the Sun, and how he made a great error, but still figured out that the Sun is much larger than Earth.
Curated OER
That Mu You Do
Students discussion frictional force, kinetic friction, and static friction and the role each plays in acceleration and velocity in relationship to a car and the road on which it is traveling. Students complete lesson answering review...
Curated OER
What's Your Latitude?
Students measure the height of items using an astrolabe. In this latitude lesson students construct a sextant and determine height and latitude with it.
