Optical Simulation of a Transmission Electron Microscope
Don't have an electron microscope? Have your classes build the next best thing! A hands-on instructional activity asks scholars to build a model of Transmission Electron Microscope (TEM). They then use their models to identify the...

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...

Collecting Electromagnetic Radiation
Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation. Materials...
