Understanding Light and Its Properties

The video tutorial covers lessons 2.1 and 2.2 on light waves, focusing on the composition of light and different light sources. Students engage in activities to determine if all light is the same, including a sorting tool exercise on skin cancer, a hands-on activity exploring sunlight in Australia, and a flashlight experiment. A simulation tests the claim that light is always the same, regardless of the source. The lesson concludes with a review of key concepts.
