Water Sphere Lens
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...

Contact Lens
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...

Magnifying Glass
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...

Curated OER
Applied Science - Technology (5A) Lab
Fifth graders explore electromagnetic waves and light. In this light lesson, 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...
Curated OER
Pinhole Viewer
Pupils make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.
Curated OER
Exploring Microscopes
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.
Curated OER
Light Gathering Power
Students compare and calculate the light gathering power of lenses. They determine the ability of various lenses and mirrors to gather light.
