Part A Science Research
Light is the energy that makes it possible for human beings and animals to see the world. Light originating from different sources referred to as sources of light. One's eyes are able to see variety light wavelength as different colours. Through light, technology around us is powered. Various form of how technology around is powered by light comprises of, cameras record light as it reflects off objects. Telescopes use lenses to bend light, laser beams make the DVD players and CD and printer possible ("Summary • Light energy", 2016).
There are various sources of light. They have been categorized into two: Natural sources and Artificial sources
Natural sources
The universe has many objects that emit light. Light emitted from these sources are able to reach the earth, but only some of it . (Jus, 2018).The following are the sources of natural light.
Sun is a major source of light in the world.. The sun is an enormous ball of fire, having the nuclear fusion at its centre producing immense energy. The light that is emitted by the sun is one of the main factors for the life on earth sustainability (Jus, 2018).The energy emitted by the sun come out as light and heat.
The moon is another source of light. The moon on its own is not capable of producing light. However it reflects light from the sun.
Bioluminescence is the ability of a living organism to produce light. This light is produced by the effects of a particular chemical reaction within the organism. Example of these organism comprises of, fireflies, jellyfish, and some deep sea plant.
Artificial sources
Artificial sources of light are those light that produced artificially. They are mostly known as the man-made light. These source of light can be categorized into three different sources.
Incandescent sources-the light is emitted from particular objects that have been exposed to a high-temperature heating. In the process, there is the production of both visible light and infrared light. Example include candle.
Luminescent sources-through acceleration of charges in a luminescent material, light can be produced. The most used way of producing light is through transitory current over the material. Example include electric bulb.
Gas discharge sources-light can be produced through the passing of electricity at low temperature through certain gases. Example include. Neon lamp.
Characteristic of light
Light has various characteristics and features. Some of these features include: First, light travels only in a straight line. Second light travels at a very high speed of 332 meters per second through the air as a medium of transmission. Thirdly light can be diffracted, reflected and refracted (Meena, 2016).
Shadows and eclipse
A shadow is referred to as a black region that is formed on a wall when the light hits an opaque object. Opaque objects are objects that do not permit light to pass through it. Since light cannot pass through a solid object, a black area is noted on the screen. Umbra refers to the dark area on the wall. Penumbra refers to the area surrounding the region that is dark. Depending on the source of light position and the distance that light is from the object, shadows do change correspondingly ("Summary • Light energy", 2016).
Formation of eclipse
When there is the prevention of transmission of light from the sun to the earth, eclipse is formed. Nonluminous body refers to bodies that do not produce their own energy, an example is a moon. The shape of the moon will change as it orbits the earth. During occurrences when half-moon is seen, this clearly means that only half moon is reflected by the sun. Eclipse is categorized into two, lunar and solar eclipse ("Summary • Light energy", 2016)
A solar eclipse takes place when the moon blocks out all the rays from the sun from reaching the earth. During this occurrence, some parts of the world experience partial darkness while others experience total darkness. For the solar eclipse to happen, the moon has to be between the sun and the earth ("Summary • Light energy", 2016).
The lunar eclipse-lunar eclipse occurs when the rays from the sun are blocked by from reaching the earth by the moon. During such occurrences, some of the earth region experience total darkness while other experience partly blackout ("Summary • Light energy", 2016).
Reflection of light refers to the bouncing back of the light once it strikes a surface that is smooth or polished ("Light Absorption, Reflection, and Transmission", 2016).
Terminology of reflection of light
Reflected ray -is the ray directed outwards from the surface.
Angle of incidence- is the angle between the normal ray and the incident ray
An angle of reflection -is the angle between the normal ray and the reflected ray.
The normal ray- is the ray perpendicularly to the surface that is polished or smooth.
Light refraction.
Light has the capability of traveling through various materials. The direction at which light travels can change, the bending or changing of light direction refers to the refraction of light. Refraction of light is likely to happen when there is a bend of light to an optically denser medium from a less dense medium.
Keywords
Light-light is a form of energy that is visible to human beings.
Colour –white colour can be split into light spectrum.
Reflection when the light hits an object and bounces back.
Refraction- bending of light when it passes from a higher medium to a lesser medium.
Translucent-materials that allow light to pass through but you cannot see through them clearly.
Opaque.-Materials that do not allow light to pass through it completely.
Ray – a narrow beam of light.

Part B Questions: . [approx 300 words]
Interview Date: Time:
Place (at child’s home, park etc): Child’s age: Child’s year at school: Child’s gender: Tell me about your experience at school? Tell me about your favourite teacher and the subject she teaches you? What do you recall about science subject in first grade up to third grade?
Who is your current science teacher? What is a science like for you? Do you enjoy the science class? What do you find most interesting about science? What is light and where does it come from?
Does the sun goes around the earth or the earth goes around the sun? What are some sources of light? Can the light be bend? Can light travel through a wall or dark thing?
Draw your shadow on this piece of paper. What is a shadow in your opinion? What causes a shadow? How did you come to figure out about that information regarding shadows?
If you want to make an object shadow what are the requirements that you need? You can know when it's daytime because you can see a lot of things like cars animals plant. When it's night time it’s very difficult to see these things. What do you think is the reason behind that? How does light help human being see things, how is that even possible, what is your point of view?
When you look in the mirror you will see a reflection of yourself, what causes that to happen? How does the mirror replicate your image?

Science concepts or misconceptions the child holds
How you know: quote the child, explain misconception & link to relevant academic literatureA child holds a misconception about the energy temperature and heat.A child holds a misconception about the energy temperature and heat. Like many other misconceptions of objects producing their own heat, the child said that she always feel warm after putting on a sweater or putting on warm clothes. Childs believe that cold and heat are substance as opposed to being energy. With the child experience with fridge and coolers, they believe that cold can be transferred from one object to another. In relation to heat, here are some of the misconception held by the childs: heat is a substance rather than an energy. Some of the substance, when exposed to heat, cannot heat up.
Contrary to the misconception held by the child, heat is a form of energy. Heat originates from either the artificial sources or the natural sources. The universe has many light emission objects. The list below contains all things that are able for light emission: sun moon, stars. Artificial sources of light are those light that produced artificially. They are mostly known as the man-made light. These source of light can be categorized into three different sources. Luminescent sources, gas discharge sources, and Incandescent sources.Childs have a misconception about the nature of light, the speed at which light travels image formation and behavior of light and color formationChilds have a misconception about the nature of light, the speed at which light travels image formation and behavior of light and color formation.it is a misconception that light can only be reflected from surfaces that are shiny in nature. The child believes that an object cannot absorb and reflect ligh,.it only has the capability of doing one of the two. It is true that all objects do reflects the absorbed light to various degrees. One’s ability to see an object will depend on the reflection of light. The child’s had a misconception the light received on earth comes directly from the sun. The truth is that the sun is very far from planet earth. The sun does not heat directly the earth instead, the light from the sun is reflected and absorbed by earth object. The light that is absorbed usually increases the object energy, causing the object to heat up.
