: S2E7 is titled "Where Pleasant Fountains Lie".
: It introduces the basic use of lenses and prisms to manipulate light paths.
: Teachers use video sheets with multiple-choice and short-response questions to ensure students are tracking the key concepts.
: Complementary lessons often involve measuring angles of reflection and refraction using tools like the PhET Bending Light simulation or physical prisms. Alternative Media Reference
This episode is frequently used in 6th-grade science curricula to help students visualize abstract concepts. Educators often use the following resources to supplement the viewing:
: S2E7 is titled "Light and Shadows" and deals with Spock’s backstory and the "Red Angel" mystery.
: The episode illustrates how light interacts with surfaces through reflection (bouncing) and refraction (bending when passing through different materials like water or glass).
