EXPERIMNT

How to make a Rainbow in a tube:

Materials:

For do this experiment we need...

-4x GLASSES

-MINI TUB TEST

-SYRINGE

-4X FOOD DYE

-SUGAR

-60 ML WATER

Procediments:

First we put the sugar in the glasses, in the first glass we put a spoonful of sugar,in the second glass we put 2 spoonful of sugar and so on.After we put the 60 ml of water in every glass(we create a sugar water solution),after we have to dissolve the sugar in the water.

Then in the glass number 1 we put red food dye,in the glass number 2 we put yellow food dye,in the glass number 3 we put green food dye and in glass number 4 we put blue food dye.

And finish we take a mini test tube and we put the blue sugar solution at the bottom of the test tube with a syringe after that we put the green sugar solution on the blue sugar solution and so on with the other solutions.

Conclusions:

The sugar solutions have a different density because we put +/- spoonfuls of sugar,then we say that a solution is thicker than the other this means it has more density.
