Students examine the idea of "regularity" as it pertains to geometry.  In this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.

Students compare and calculate the light gathering power of lenses. They determine the ability of various lenses and mirrors to gather light.

Learners study the movement of light. In this light lesson plan, students work in groups to participate in a light and shadow walk around their neighborhood. Learners brainstorm rules for light movement and watch videos about light...

Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...

Young scholars construct a simple refracting telescope. They calculate the magnification.

In this aurora worksheet, students read a description of an aurora observed by Captain Standard in 1859. Students interpret the description with a drawing giving as much detail as possible using colored media to capture what they read.

High schoolers investigate the interior angles of a triangle. In this geometry lesson, students create the formula to calculate the angles inside a triangle. They observe the total sum of a triangles angle on the navigator.

Eighth graders describe how light behaves when it strikes a surface. In this physics lesson, 8th graders investigate how the different types of mirrors reflect light. They work with their chosen group on a task they selected.

Students make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.

[Free Registration/Login may be required to access all resource tools.] Students describe and predict image formation as a consequence of refraction through a thin convex lens.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn how to draw ray diagrams and to solve problems for concave and convex mirrors.

An in-depth discussion on reflection of light can be found here. Among the topics discussed include are the difference between specular and diffuse reflection, concave and convex mirrors, facets, total internal reflection, and much more....

This passage will test your knowledge on lenses.

A comprehensive guide for learning all about convex shapes with definitions, examples, and practice questions.

Article explaining what lenses are and how they work. At the end of the article, there are links to several hands-on activities for investigating lenses.

Illustrated diagrams in this tutorial help students understand the properties and functions of lenses.

A four-lesson tutorial on the reflection and the ray model of light. These complete tutorials include informational text, interactive activities, animations, and quick, interactive comprehension questions.

This lesson focuses on polygons; a polygon is a closed, flat shape that has only straight sides. Polygons can have any number of sides and angles, but the sides cannot be curved.

This website, although mostly for selling artwork prints by M.C. Escher, provides a good picture of Escher's famous piece lithograph, "Convex and Concave." Includes some informative text.

In this physics tutorial, we will follow a pattern of inquiry for convex mirrors: investigating how convex mirrors reflect light and produce images.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to calculate the sum of the interior angles of a polygon and the measure of one interior angle of a regular polygon.

While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and image size. To obtain this, students are introduced to the Mirror Equation and...

Learn about convex polygons with this handy reference guide. Provides a detailed definition, examples, and an interactive activity that enhances further explanation. Includes links to related topics.
