Light Waves and Melanin Concepts

The video tutorial covers Chapter 2, focusing on light as a wave. It includes five lessons: investigating light sources, harvesting sunlight, wave properties, light's effect on genetic material, and analyzing evidence about melanin and UV light. Each lesson involves activities such as warm-ups, hands-on experiments, simulations, and article readings to explore the properties and effects of light.
