In this viewing of a cell worksheet, students will read a paragraph about how microscopes work and will use a diagram of a light microscope to complete 2 short answer questions.

A lamp, four globes, and some signs taped around the room are all you need to set up a solar system simulation for teaching how Earth's tilted axis creates the seasons. (Sticky dots are also needed, but not mentioned in the materials...

In this online interactive reflection and refraction worksheet, students respond to 7 multiple choice and fill in the blank questions regarding the information included in the provided paragraphs.

Students classify the visual opacity of various materials, what is needed to create shadows, and classify clouds by the types of shadows that they produce.

Students classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.

Site studies light refraction and provides illustrations several illustration. Contains links to Snell's Law, lenses, ray optics, light and much more.

This illustrated physics tutorial serves as a step-by-step guide to drawing ray diagrams. It includes an opportunity for students to practice and check their answers.

In this physics tutorial, students investigate the method for drawing ray diagrams for objects placed at various locations in front of a concave mirror.

Ray diagrams are useful tools for determining the location of an image as produced by a concave mirror. Of all the rays which emanate from the top of the object arrow and are incident to the mirror, there are two rays whose behavior at...

In this illustrated tutorial, students will see a specific method for constructing ray diagrams for double concave lenses.

Six complete lessons on refraction and the ray model of light. Tutorials include informational text, interactive activities, animations, and quick, interactive comprehension checks along the way.

An illustrated tutorial which takes students step-by-step through the process of drawing ray diagrams.

Using the diagram provided, calculate where a ray of light coming through a pinhole hits an image plane.

Site provides a diagram as well as a scientific explanation of light reflection. Includes links to ray optics, light and physics.

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.

In this lesson, students learn that light travels in a straight line from a light source and that ray diagrams help us understand how an image will be created by a lens. In the accompanying activity, students explore the concepts behind...

A discussion of Christian Huygens' contribution to wave optics, and particularly to our understanding of the reflection and refraction of light. Excellent diagrams and a geometric proof on why the law of reflection is mathematically...

Lesson 3 of this tutorial on refraction is on concave mirrors. Content that is covered includes the anatomy of curved mirrors, reflection of light and image formation, ray diagrams, image characteristics for concave mirrors, plus more.

A tutorial which demonstrates how ray diagrams can be used to determine what portion of a plane mirror must be used in order to view an image.

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

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...

This page is a continuation of a tutorial about light reflection and refraction. It contains a diagram and suggestions on how to derive Snell's Law, which governs the refraction of light in a medium. For background to this derivation,...

Through diagrams and illustrations, students explore how images are formed through the physics law of reflection.
