Students observe an activity with Jell-O to learn about optics.  In this investigative lesson students fill out a handout on the activity that helps them to investigate the index of refraction and the speed of light. 

Students are introduced to the wave nature of light. In groups, they discuss Young's experiment and how diffraction and interference demonstrate the wave nature of light. Using examples, they show constructive and destructive...

Fifth graders view a Powerpoint show about reflecting light. They experiment through a reflection simulation on the internet. Students complete the activity by using mirrors and light to complete send light to a specified spot.

Students using a glass prism filled with water are able to see all of the visible colors found the sunlight.

In this radiation worksheet, students review the different types of radiation waves that come from space and the different telescopes used to detect this radiation. This worksheet has 17 true or false questions.

In this detecting disease worksheet, students will review the different tools scientists use to identify diseases including the steps of Koch's postulates. This worksheet has 14 fill in the blank and 4 short answer questions.

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

Students read about and discuss photographic principles and, under the direction of the art teacher, construct individual cameras from heavy black cardboard and thin sheet metal with a hole for the lens and black tape for the shutter.

For this identifying the weather terms activity, students read phrases about the weather and choose the term being described. Students choose 11 multiple choice answers.

Middle schoolers classify materials. In this chemistry lesson, students examine the properties of solids, liquids, and gases. Middle schoolers discover the elements, compounds, and chemical symbols.

In this weather crossword puzzle worksheet, students use the 16 clues and the word bank to fill in the blanks in this crossword puzzle.

Students build their knowledge and understanding of vocabulary related to space.  In this space instructional activity, students discuss four categories of words and phrases related to space. 

In this illustrated physics tutorial, students investigate several of the types of problems that you will have to solve, and learn the task of tracing the refracted ray if given the incident ray and the indices of refraction.

Students use this tutorial to investigate the refractive ability of converging and diverging lenses.

Students observe how different materials bend light, and how we can infer the nature of the material based on the amount it bends light rays.

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

In this interactive physics tutorial about refraction, students investigate the topic of the direction of bending of a light wave.

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.

Instructional module focusing on light. Discussion includes historical development of particle versus wave theories and the scientific studies leading to the understanding of light waves today. Site also includes an interactive practice...

This is a quiz covering reflected, refracted, shadow, and camera rays.

Through illustrated diagrams and animations, students explore the broken pencil phenomenon and light refraction.

This passage will test your knowledge on reflection and Refraction - Passage 2.

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.

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...
