What's More Enrichment Activity 1: "Light Reflectors" (Adapted from: Science and Technology Textbook for Fourth Year, Reprint Edition) Materials: Flashlight (the one that can be dismantled), pen and Science Activity Notebook Procedure: I Get a flashlight and switch it on. What do you observe about the beam it emits? 2. Examine the part where the bulb is positioned Q1. What do you notice? 3. Remove the reflector from the flashlight's body. Describe the reflector Note: The reflector is the silver colored matenal that surrounds the bulb of the flashlight 4. Remove the bulb and connect it to a source such that it can be moved or adjusted within the concave reflector. See figure below: os off 5. Put the bulb in a position 1. Connect to the source and switch it on. Q2. What do you observe about the beam it emits? 6. Repeat step 5 with the bulb at position 2 then 3. Q3. What are the differences of the beam intensities? 7. Summarize your observations by writing: brightest, brighter, and bright for the beam intensities in the table provided below.
