Reflection is when light bounces back when it hits an object. Refraction is when light bends while passing through one substance to another. bsorption is when light is absorbed by an object. Look at these illustrations to identify these 3 properties of light. 2 3 You learn about the properties of light. You start observing reflection, refraction, and absorption around you. nswer: 1) Reflection 2) Refraction 3) bsorption Light Source r ot nything that produces light on its own is called a light source. Some are natural and some are manmade. Look at these illustrations and circle the natural sources of light. Sun Lightning andle il Lamp arthen lamp Bulb Firefly Stick on fire Star Torchlight You learn to distinguish between the natural and artificial sources of light. Your observation skills get sharpened. nswer: atural - Sun, Lightning, Firefly, Star anmade- andle, Lamp, Bulb arthen lamp, Stick on fire, Torchlight Reflection r Refraction Reflection is when light bounces back when it hits an object. irrors, shiny surfaces, some metals, water surface, and so on reflect light. Refraction is when light bends while passing through one substance to another. Prisms, cut diamonds, soap bubbles, and so on refract light. We have put a bunch of objects. Look at them, identify and tick the ones that reflect light. Diamond oon Juice etal Surface irror Pencil agnifying glass You understand the difference between reflection and refraction. Your analytical skills improve. nswer: Reflection- irror, etal surface, oon atch The Light Terms Some terms based on lights and optics are given on one side and their definitions are all jumbled on the other side. Read and match the correct definitions. Illustrations are given for you to understand the terms better. a Focal length 1 Light bends when passing through one substance to another b 2 Dark area made when object blocks light Reflection 3 When light bounces back after it hits an object. d Refraction Shadow 4 Distance from a lens to its focus. Your observation skills are sharpened. Your science vocabulary is enhanced. nswer: a - 4, b - 3, c - 1, d - 2 hoose The Right Term ] Your friend and you are standing near a pond. She tries to sneak on you, but you see her coming. You see her in the pond because of (reflection/refraction/absorption/noise in grass) B] The bending of light is called (refraction/reflection/scattering/ultraviolet light) You choose the right answer while learning about the concepts. Your problem solving skills improve. nswer: )Reflection B)Refraction )White Light D)paque ] can be separated into a rainbow of colours. (White light/polarized light/uv light/fluorescent light) D] Light does not pass through an object that is all (opaque/transparent/shiny/translucent) nswer: )Reflection B)Refraction )White Light D)paque y Thaumatrope Thaumatrope is an optical toy that has discs with pictures on each side. When you rotate it at the correct speed, these frames combine to give you the visual of a single image. Here we have made two interesting sets of thaumatrope for you. ut them, Fold along the dotted lines, attach string on both the sides, slide them between fingers of both hands, and pull them. It s a lot of fun. You get to experience how the concept of optical illusion works. Identify e Look at these optical instruments. Read the definitions to identify them correctly. 1) ne of the earliest animation devices. strip of picture is placed around the inner surface of a spinning cylinder to create visual animation. Identify me. 2) n optical device that projects an image onto a surface or a screen. Identify me. 3) transparent solid body used to disperse light into a spectrum. Identify me. You identify the optical instruments and learn the science behind them. nswer: 1)Praxinoscope 2)Projector 3) Prism What Lens m I? Lens is an optical device that either focuses or diverges light to form an image. There are many types of lenses. Read the definition, look at the pictures, and identify the type of lens. * Plano convex lens: lens that has one side of convex lens and a flat lens (plano) on the other side. * onvex or positive lenses will converge or focus light and can form an image. * Biconvex lens are simple lenses that comprise of two convex surfaces in a spherical form, generally having the same kind of radius of curvature. * oncave or negative lenses will diverge (spread out) light rays. You gain knowledge about the different types of lenses. Your curiosity increases. nswer: onvex, oncave, Biconvex, Plano convex lens Your visual tracking skills improve. Your vocabulary relating to the concepts of light and optics is enhanced. Hidden ptical aze Hidden ptical aze There are words hidden in this word maze. Look horizontally, vertically, and look across to find them. lue: The words are all related to lights and optics.

Translucent materials let some light through, but they scatter the light in all directions and so you cannot see clearly through them. paque materials do not let any light pass through them. They block the light. Look at these objects and group them as transparent, translucent, or opaque.
