Light power!

science day

   Today was a cool day... a science day! 
we did science experiments on light 
  we did lots of different things with light like  Spectrum, Color, reflection. We used mirrors, Lego,  water ice, colored paper and of coarse light

 I enjoyed the ice and paper experiment  because it  was interesting to see what ice cube melted the  fasted was black. I think it was because it takes in  the heat and the second piece of ice that melted the  the piece on top on the piece of white paper but  I don't know why. I learnt who invented light his name was Thomas Edison's. The part was trying to make light bounce off mirrors around in a circle. I was surprised when the spoon reflecting worked my group worked well when we were trying to figure out the make light bounce. There is three different kinds of things in the world translucent ( means you can't see threw it ) transparent ( means you can see threw it ) and opaque ( means you can very dimly see threw it )
   









HERE ARE SOME GAMES TO DO WITH LIGHT

Making Light Bounce

Objective

To demonstrate that light travels in straight lines.

Materials

3 or mirrors

Flashlight

Book

Experiment

1. Set up a book on a table so that its’ standing. Point your light at the front side of the book. What happened to the beam of light?
2. Lean the mirror against the front of the book so that its standing. Point the light at the mirror and turn it on. What happened to the bean of light?
3. Have a friend help you use 2-3 mirrors to direct the light beam to the backside of the book through reflection. Try many different ways to do this. Draw diagrams of each path you create to reflect the light to the back of the book.

Prism Play

Objective

To demonstrate that a Isaac Newton was the first to discover that each beam of light is composed of a full range of colors.

Materials

Torches

White paper

mirror

Tub of water

Black card

Colored translucent colors (cellophane)

Experimental Procedure

Use the black paper to cover the flashlight beam, but first cut a small slit in the center of this piece of paper. Fill a small, clear, plastic tub with water and lean a mirror in the water at one end of the tub. Shine the light on the mirror. Hold up the blank white paper to catch the reflected beam of light.

Concave and Convex

Objective

To discover convex and concave objects and how they reflect light.

Materials

Spoon

Torch

Experiment

1. Hold the spoon with the bulged-curved side directly facing a flashlight around 8 cm. Turn the light on. What do you see? Fill in your sheet
2. Now flip the spoon over to the curved - inwards side and shine a light at it as you did in step one. Now what do you see?
3. Compare the difference in light reflection
