Students explore scientific observations by examining the parts of a microscope. In this optics instructional activity, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a...

High schoolers experiment with a converging lens. They observe the image of an object through a lens. They determine the magnification of the lens.

Young scholars construct a simple refracting telescope. They calculate the magnification.

Learners 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.
