Let's get acquainted!
Light the flashlight and show the crumb a ray of light. You can use a laser pointer. Invite the baby to continue the phrase: the light is ... Help the child to conclude that light is a ray that can illuminate objects.
Stolen Sun
Read the famous poem "The Stolen Sun" by Korney Chukovsky, of course, the child will understand that it is light in the daytime, because the sun illuminates and warms the earth.Take a globe or an ordinary ball and a flashlight.Let the crumb imagine that the ball is our Earth , and the flashlight is the Sun. Shine on the ball with a flashlight and explain to the kid that one side of the Earth is turned to the Sun and is illuminated by the sun rays in the daytime.This rays allow us to see everything in the day. And why can not we see in the dark? Let the child fantasize, but in it n is important to draw a conclusion, we see that the illuminated light.
Luchik the traveler
A ray of light has a beginning (source) - everything that light gives. Ask the baby to remember and name as many light sources as possible. This is the sun, and an ordinary bulb, and even a candle. The ray of light moves very fast. To prove this, turn on and turn off the flashlight several times in a row. Shine a flashlight on different objects and tell the kid that the speed of light is the highest, you can not move at the same speed in the world. Invite the crumb to catch a ray of light.
Where is the beginning, where is the end?
Now we understand that we can not catch the light. Is it possible to stop it? An interesting experience will help answer this question. Turn on the flashlight and ask the children to find the beginning and end of the light beam. If the beginning is easy to find, then the end of the ray does not seem to exist. This is because if the beam does not meet obstacles, the tone continues until it loses its strength and dissipates.
The dog has disappeared
Explain to the kid that a ray of light always goes straight, he can not turn aside. For the kid to remember this, draw a creative drawing. Give the baby a piece with the image of the child in one part of the leaf and the dog in the other. Tell us that the baby lost a puppy and it must be found. Let's draw a flashlight with a beam of light so that it illuminates the lost dog. Remember that a ray of light always goes straight.
Trap for light
And what happens if the beam meets a barrier in its path? Prepare any figure carved from cardboard, attach it with tape to a cocktail tube or pencil. Put the figure between the wall and the light source, light the cardboard figure with a flashlight, bringing the figure closer to the wall, then to the light. We will see a shadow on the wall. The closer the figure to the lantern, the more its shadow on the wall. The farther the figure from the lantern, the smaller will be its shadow on the wall. This is because the rays from the light source fan out. If the object is far from the source, it blocks less light and vice versa.
In the theater of shadows
Invite the kid to arrange a real theater of shadows and play in it excerpts from favorite fairy tales. Take a piece of white cloth on the frame or Whatman, as well as paper figures of fairy-tale heroes. A frame with a cloth light the flashlight from the back. You can start the show! And also teach the children to show the fingers of the shadows of different animals. Playing with a child is great, is not it? Therefore, spend more time with your child and pay attention to it.
