SLANT S-Sit up L-Listen A-Ask and answer questions N-Nod your head T-Track the speaker 1) when light passes through concave a lens it …………………… a. it refracts and diverges b. It reflects and diverges. c. It refracts and converges. d. it passes through lens without any change. 2) question : Describe the phenomenon happening in the diagram. ( Hint- use only 2 verbs) NNJR NNJR I Do We Do You Do Plenary Answers 1) Light refracts and diverges 2) Light refracts and converges.

Which part of the eye controls the amount of light entering it? A) Cornea B) Lens C) Iris D) Retina 2. What is the function of the retina in the eye? A) To control light entering the eye B) To focus light onto a single point C) To detect light and send signals to the brain D) To protect the eye from dust 3. The lens in the eye adjusts shape to focus on objects at different distances. This process is called: A) Contraction B) Accommodation C) Reflection D) Magnification 4. What is the function of optic nerve? Verbal AfL I Do Verbal AfL We Do Mini-Plenary You Do LFQ: How do cameras and eye work? ANSWERS 1. Answer: C) Iris 2. Answer: C) To detect light and send signals to the brain 3. Answer: B) Accommodation 4. It sends reflexes to brain from eye so that we sense what we see.

We Do Verbal AfL We Do Mini-Plenary You Do Plenary LFQ: How do cameras and eye work? Extended challenge. Why might it be difficult to see colors in a dark room? In low-light conditions, rod cells are more active because they are more sensitive to light, while cone cells are less active. Since cone cells are responsible for color vision, the lack of light leads to a diminished ability to distinguish colors, making everything appear in shades of gray.
