Comparison of Images Formed by Plane, Cylindrical (concave side), and Spherical (concave side) Mirrors
Young scholars study mirrors and see how images can be reversed. For this reflection lesson students demonstrate that all mirrors reverse images and that the apparent right to left reversal in a plane mirror is a result of that reversal.

Stretching the Quads
Scholars investigate transforming parabolas. In this transforming parabolas instructional activity, they take the parent graph y=x^2 and transform it by shifting left, right, up, and down and shrinking and stretching. The class finds...
Curated OER
Exploring the Landscape
Young scholars determine the monotonicity and concavity properties of a function, then apply the First Derivative Test and draw conclusions about the first and second derivatives from these properties.
Curated OER
Lenses and Telescopes
Learners examine telescope construction. In this telescope lesson, students examine the lenses used in telescopes by exploring with convex and concave lenses.
