Gummy Bears and Lasers (Lesson)

Gummy bears, as it turns out, are great for demonstrating the otherwise abstract concepts that describe the most basic of light-matter interactions: absorption, transmittance, and reflection.

Audience: Grades 7-12

Time: 30-45 minutes

Key Terms: Absorption, Transmittance, Reflection, LASER, Wavelength, Frequency

Optics and the Human Eye (Lesson)

The rules of optics are predictable and finite. People interact with light reflection and refraction on a regular, constant basis. Students are likely familiar with reflection and refraction concepts, but this simple demonstration can help them gain a new understanding. Using lasers, students will investigate reflection and refraction, lens and mirror properties, and optical devices.

Audience: Grades 7-12

Time: N/A (Supplemental Demonstrations for the classroom)

Key Terms: LASER, Reflection, Refraction, Lenses, Mirrors
