Students examine telescope construction. In this telescope lesson, students examine the lenses used in telescopes by exploring with convex and concave lenses.

Did you know some retailers use curved mirrors in their fitting rooms to make customers look thinner? Pupils view themselves in convex and concave mirrors to understand the difference. The resource includes big ideas for multiple age...

Students learn to differentiate between different types of lenses. In this lens lesson, students discover how lenses are different and why a specific lens should be used. Students understand how to find the focal point of a lens....

Students explore vision by experimenting with lenses in equipment. In this optics lesson, students define the different technology that enhances vision such as microscopes, telescopes and cameras. Students experiment with these devices...

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...

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.

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.

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.
