With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...

How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance...

How can a magnifying glass or reading glasses make things appear larger? Scholars simulate moving a lens closer or farther from an object to observe the resulting image. They also alter the lens focal length. The simulation shows the...

In this space activity, students will review different aspects of light, sound, and radio waves in space and the use of different types of telescopes. This activity has 17 fill in the blank statements.

Fifth graders explore electromagnetic waves and light. In this light activity, 5th graders draw the parts of a wave of the electromagnetic spectrum. They compare a flashlight to a laser to see how the light looks when shined through...

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

Students explore the parts of a microscope. In this microscope lesson, students examine simple and compound microscopes. Students discover how the parts of a microscope work together to generate an image.

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

[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.

This lesson explains what lenses are, the different between a converging and diverging lens, the difference between a double convex and double concave lens, and gives definitions for terms related to lenses.

[Free Registration/Login Required] Learn about the type, size, location, and orientation of the image that forms when a thin lens is used to view an object using this interactive simulation. A PDF worksheet and a video tutorial are also...

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