Learners examine the Stefan-Boltzmann Law. Students compute basic radiative "constants" of the sun-Earth-atomosphere system. They examine the wavelength of maximum radiation emission.

Students explore the nature of electromagnetic spectrum through a series of experiments. For this physics lesson, students determine how light behaves under certain circumstances. They explain how humans perceive colors.

In this figurative language worksheet, learners identify the figurative language technique being used in each of the 10 sentences. The sentences are based on Edgar Allan Poe's literary work.

High schoolers 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...

Students observe a demonstration of light refraction. They experiment with disappearing crystals to further study light refraction.

In this literature response activity, students answer 20 short essay questions about Chapter 14 of the book called Holes by Louis Sachar.

In this radiation worksheet, students calculate the distance of a satellite in orbit to determine the placement of a radiation detection device. This worksheet has 2 problems to solve.

In this math worksheet, students sketch the regions that give rise to the integrals. Then rewrite them as double integrals with the integration order reversed.

In this math activity, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students investigate the law of reflection by using mirrors. In this physics lesson, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

Explore lines and angles, and the relationship between the two.

[Free Registration/Login may be required to access all resource tools.] Understand how angles are formed and identify an angle's rays and vertex. Students can master the concept by watching a video, examining guided notes, reviewing...

Illustrated examples and interactive practice problems that introduce students to the concept of the critical angle, the angle of incidence that provides an angle of refraction of 90-degrees.

Through an illustrated tutorial and some interactive practice problems, students learn about the law of reflection of light.

In this illustrated physics tutorial, students investigate the connection between light reflection and light refraction.

The meaning and cause of refraction--as well as Snell's law of refraction--are discussed. Includes an interactive problem-solving form in which visitors relate angles of refraction to the incident angle and the indices of refraction.

Discover how light reacts when it strikes mirrors which are placed at right angles to each other.

This fourth-grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole...

In this instructional activity, students will identify and draw lines, segments, rays, angles, and points.

Explains the terms and symbols used to discuss line angles, what an angle is, and the types of angles. Includes short video lesson demonstrating how to use a protractor to measure an angle. [0:57]

In this interactive physics tutorial, students will learn about a mathematical equation relating these two angles and the indices of refraction of the two materials on each side of the boundary.

Intermath Dictionary's site defines terms relating to angles, gives examples, and offers interactive exercises.

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.

Determine which angle has a greater measure by looking at the size of the opening between the angle's rays. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
