Sixth graders create polygons. In this shapes lesson, 6th graders explore prefixes such as oct, tri, quad, pent, etc. and share their findings. Students use pattern blocks to create two different polygons and label them.

Students create their own cameras to understand how artists use light to capture an image in a photograph. For this light lesson plan, students use tape, wax paper, rubber bands, and more to create their cameras.

Students explore vision by experimenting with lenses in equipment. In this optics instructional activity, students define the different technology that enhances vision such as microscopes, telescopes and cameras. Students experiment with...

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

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

Students are introduced to the art of stone masonry. They identify the seven basic stone tools, demonstrate their use, and compile a list of their cost.

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...

Students analyze a microscope and study what they do.  In this investigative lesson students study how microscopes were first invented, and how ray diagrams are used in conjunction. 

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...

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...

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

[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.] Find the sum of the interior angles of a convex polygon.

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

Students learn two rules of reflection as it has to do with convex mirrors. These two rules will greatly simplify the task of determining the image locations for objects placed in front of convex mirrors.

Students explore three different ray diagrams for objects positioned at different locations along the principal axis in a convex mirror.

[Free Registration/Login Required] Change the focal point in this interactive convex lens to see how the focal length changes. After the activity, answer a challenge question to check for understanding.

[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.

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.

[Free Registration/Login Required] Students will move the pentagon points to explore convex polygons. Click learn more to watch a video and click challenge me to answer a practice question.

This site defines a convex polyhedron in terms of vectors and matrices. A table of examples, as well as an illustration, are given. This site has numerous links to related Math World sites.

[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.

An investigation into how lenses behave. Students explore using convex and concave lenses in various ways and record their observations. They are then are directed to another site to try activities where they can manipulate virtual lenses.
