Curated OER
Lenses and Telescopes
Students examine telescope construction. In this telescope instructional activity, students examine the lenses used in telescopes by exploring with convex and concave lenses.
Curated OER
Building a Telescope
High schoolers construct a simple refracting telescope. They calculate the magnification.
Curated OER
Lenses
Students explore vision by experimenting with lenses in equipment. In this optics instructional activity, students define the different technology that enhances vision such as microscopes, telescopes and cameras. Students experiment with...
Curated OER
A Distant View
Students investigate the essential concepts of how lenses work to magnify vision, and then build simple telescopes to demonstrate their understanding. They write a description of how their telescope could be improved and how it works.
Curated OER
Light and Optics
Third graders utilize the scientific method to explain light and optics in this five lessons unit. Through experimentation and discussion, 3rd graders canvass the concepts of light traveling, reflection and refraction.
Curated OER
Microscopes and Telescopes
Young scholars analyze a microscope and study what they do. In this investigative lesson students study how microscopes were first invented, and how ray diagrams are used in conjunction.
Curated OER
Light Gathering Power
Learners compare and calculate the light gathering power of lenses. They determine the ability of various lenses and mirrors to gather light.
Curated OER
Exploration of Light
Fifth graders observe the video, Exploring Light and Color. They access a website to create their own light show. They conduct lab experiments to investigate refraction, reflection,and other light-related topics.
Curated OER
Pinhole Viewer
Students make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.
