The rainbow density lab
Materials:
-Scale/Balance• One 50 mL Graduated
Cylinder
- Two 150 mL Beakers
- Pipette
- A sheet of white background paper
- in this case, we used our lab worksheets - This is used by putting it behind
your completed work to see more clearly of the blended layers of the
colors
-Salt
- Food Coloring - Red, Orange, Yellow, Green
and Blue
- Water

Beaker 1:
After stirring the beaker with the salt, we got a pipette with some blue
food coloring, and slowly, one by one added three drops of the blue coloring
into our beaker. Mrs. Ogo had told us earlier to add a few more drops of food
coloring if we needed to, since the colors turned out too light. We did that and
that's why we added one more drop of blue in.
After that happened then, we began adding the blue solution into our 50 mL graduated
cylinder.

Beaker 2:
Next measured out 11.7 grams of salt. Once the measuring was done, I carefully carried the salt
over to where my partner was sitting and poured in the salt. While she was
stirring that beaker, I got my pipette and cleaned it up and got some green food coloring.
Then we added the solution to the 5o mL graduated cylinder.

Beaker 3:
Next, we did the yellow. We measured out 7.2 grams of salt. I
quickly, but gently, poured the salt into that beaker, and let my partner stir
the solution up. I went and got the yellow food coloring with my pipette and
dropped two into the beaker.
Then we added the solution to the graduated cylinder.

Beaker 4:
Next we had to do orange so we added water to our beaker .
Then we measured out 3.4 grams of salt. Then I put several drops of red food coloring and yellow
food coloring, to make orange.
then we added the solution to the 50mL graduated cylinder.

Conclusion:
To conclude this lab, we all can say that salt has a density effect (a lot really). If you add salt to a specific color with water it will have huge effect on the density. There are several layers of denser and less dense water which is why all the light colored water is on top. I don't know if its inly the salt that effects the density, maybe not maybe the color affects the density. Finally Check again if your lab did not work check your data, retry and go slower.
