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.
Results:
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.
