The 3 experiments for children produced by light

Bringing science closer to the little ones in the house can always be a difficult task. Luckily, there are many experiments for children where light and color are the protagonists and with which we will get the little ones to have fun learning, as well as being surprised.

The interest in learning cannot disappear in children, despite the fact that we move in a world where technology, video games or television, take the greatest interest for the little ones, and we must make them enthusiastic about other things such as science or manual experiments.

The shrinking spoon

To prepare this experiment for children we only have to have a large plastic container, a spoon and water. To begin we fill the container with the water until it reaches the top. Ideally, this container has a capacity of approximately one liter.

Once we have the container full, we submerge the spoon until half of the water. The effect that it produces is that the spoon so that it shrinks that it becomes very small. This is due to the refraction of light in the water, when passing through the water, the rays of light are bent up to our eyes, which is why this particular effect occurs.

Newton’s disk

Invented by Isaac Newton himself, this round disk must be painted in sectors with the fundamental colors: red, orange, yellow, green, blue, indigo and violet.

We can do it in an old cardboard that we must cut in the shape of a circle. An old CD that we have can help us to guide this. Once cut , we will divide it into seven sectors where we will paint each one of a color.

Once like this, we turn it with force and the child will discover that when turning the circle with speed, the resulting color is white. Thanks to the range of colors used, that of the rainbow, when the human eye sees you at high speed, it ends up seeing the color white, the result of all of them.

Projected lights

This is a very simple experiment for children. We only need a few empty glass jars that we will fill with water to a little more than half.

Then, with food coloring, in each bottle we will use a different color, pouring in proportional quantities so that the color takes shape in the water.

Finally, we will turn off the light and take a flashlight . When we project the light onto a boat, the color of the one that has been painted will be projected onto the ground, creating a very significant optical effect for children.

Slaves and Disabled: Forced Medical Test Volunteers

The main problem to carry out medical research is to have willing volunteers for it. And if they come out for free, much better. This is the story of unethical behavior in medical research.
