Cassegrain Telescope
How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....
Cornell University
Beam Focusing Using Lenses
Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...
Curated OER
Spherical Mirrors
Students view images in a spherical mirror and interpret the path of light. In this physics lesson, students view a large spherical mirror demonstrated by the instructor. They use shiny serving spoons to investigate the path of...

Building a Compound Light Microscope
What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...

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
Extreme Flashlight Tag
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.
Curated OER
To See or Not to See: The Colors of Light
Seventh graders describe and conduct an experiment that identifies the physical properties of light. They explore sources of visible light and an electromagnetic spectrum. Students explain the conversion of one form of energy to another.
Curated OER
Applied Science - Physics (5B) Post Lab
Fifth graders analyze optical images. in this optical lesson, 5th graders look at how light reflects and refracts. They discuss different types of lenses and how they change the picture that is taken.
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.

Microscopes and Telescopes
Students analyze a microscope and study what they do. In this investigative instructional activity students study how microscopes were first invented, and how ray diagrams are used in conjunction.
